Community Character Map

An ancestry model for Greendale's ensemble, with a working index.

Working index, not finalNewsRadio leads the index at 94Buffy rejoins at 92New focus: Saved by the Bell and NewsRadio lineagePlanbee to Ladders, the consultant handoff

The premise

NewsRadio is the organizing premise, the hypothesis that started the project, and it holds the strongest cast-level correspondence in the current scoring. Every show is scored by the same declared method.

Every evidence row carries one of six labels. EpisodeCommentary heardProduction recordPersonnelPublished reviewInterpretation

Commentary heard directly counts as evidence under its own label, with or without a transcript online.

Saved by the Bell and NewsRadio into Greendale

The current focus is the line from Saved by the Bell and NewsRadio into Community. A commentary heard directly confirms one point of that lineage. It is recorded under Commentary heard, it is not linked, and it anchors that single point rather than the whole argument, which the rows below carry on their own evidence. Every link below is new to this project unless its row says otherwise, and each is tied to dialogue, recaps, episode records or credits that the build checks on both sides. Commentary heard

The earlier finds, including "Jessie's Song", "The Zack Tapes", "Daydream", "Copy Machine" and "Station Sale", are on the Greendale Lineage page. The Planbee handoff and the Annie line from Jessie to Frankie are on that page too.

No line of Community dialogue names either show, WNYX, Bayside or their lead characters. In Wikipedia's episode credits, Jeff Melman is the only director or writer on both a Saved by the Bell production and a Community episode, no NewsRadio director or writer is credited on Community, and seven NewsRadio guest stars plus one regular, Andy Dick, turn up at Greendale.

Shared performers and production bridges

WhoOlder showCommunity
Jeff MelmanDirected the TV movie Saved by the Bell: Wedding in Las Vegas (1994).Directed "Remedial Chaos Theory" (S3E4). Why it matters: he is the only director or writer credited on both a Saved by the Bell production and a Community episode, so the lineage runs through the crew and not only the cast, and the episode he directed is the one where Community splits its ensemble into seven timelines. The show's most formally ambitious hour was handed to the one person who had already worked on Bayside. PersonnelProduction record
Tiffani-Amber ThiessenKelly Kapowski on Saved by the Bell, then Foxy Jackson on NewsRadio, the new assistant Joe is smitten with ("Assistant", February 16, 1999).No Community role. She joins the two older shows through Joe, Troy's ancestor. Why it matters: she is the single performer who ties Saved by the Bell directly to NewsRadio, and the character she plays there is the woman Joe falls for. The connection between the two older shows therefore lands on the exact character Troy grows into, so the Bayside side of the family tree enters NewsRadio through Greendale's future repairman. PersonnelEpisodeInterpretation
Andy DickMatthew Brock on NewsRadio.The tiny pilot in Pierce's painkiller visions in season 2, credited as Helicopter Pilot/Tiny Man. Why it matters: he is the only NewsRadio series regular, rather than guest star, to appear in Community, so the strongest single casting link between the two shows runs through the actor who played Matthew, the ensemble's odd one out. He arrives at Greendale inside an older comic character's drug hallucination. Personnel
French StewartBrent, the "weird" new temp Matthew feels threatened by ("Mistake", May 14, 1997).Vinnie, the look-alike agency boss Abed owes three grand ("Contemporary Impressionists", S3E12). Why it matters: both roles put him opposite the ensemble's odd one out as a threat. On NewsRadio he is the new temp whose strangeness unsettles Matthew, and at Greendale he is the man Abed is in debt to. The same performer plays the outsider who destabilises whichever character occupies that seat. PersonnelEpisode
David CrossMr. James's nephew Theo ("Houses of the Holy", March 10, 1996) and David from Dave's college a cappella group ("Chock", January 13, 1998).Hank Hickey ("Advanced Advanced Dungeons & Dragons", S5E10). Why it matters: both shows cast him as the difficult younger male relative of an older authority figure. On NewsRadio he is Theo, the station owner's nephew, and at Greendale he is Hank, Buzz Hickey's estranged son. The role is the same family position twice, and in both cases the older man's standing in the group is what the younger man comes to test. Personnel
Patton OswaltGuy in "The Trainer" (December 19, 1996), the episode where the WNYX staff discover a secret about Dave's past. Ben Stiller guests in the same episode as Vic.Nurse Jackie in "Home Economics" (S1E8) and "The Psychology of Letting Go" (S2E3). Why it matters: the NewsRadio episode he appears in is the origin of the boss-knows-too-much material, where the staff learn something about Dave he had kept from them. That is the structure Greendale gives the Dean, who holds information about Jeff and the study group he should have no access to. Personnel
Paul F. TompkinsThe justice of the peace in "Wedding" (March 2, 1999).Robert, the fellow sci-fi fan Abed talks with in "Mixology Certification" (S2E10). Why it matters: both roles are the outside adult who briefly legitimises something the ensemble cannot settle by itself. On NewsRadio he holds the legal authority that makes a marriage real, and at Greendale he is the stranger in a bar who takes Abed's obsession seriously and treats it as worth an adult conversation. Personnel
Brian PosehnBrian in "Chock" (January 13, 1998) and a fan in "Super Karate Monkey Death Car" (November 4, 1997).Bixel in "App Development and Condiments" (S5E8). Why it matters: he is the only performer here who appears in two NewsRadio episodes that both have Community counterparts on this page. "Super Karate Monkey Death Car" is the polygraph episode paired with "Cooperative Polygraphy", and his Greendale role sits inside the MeowMeowBeenz episode paired with "Rose Bowl". His casting lands twice inside pairings the map already carries. Personnel
Michael McDonaldA guest star in "Airport" (February 19, 1997).Ronald Mohammad in "Basic Story" (S5E12). Why it matters: his Community role sits inside the episode where Greendale is to be sold and replaced by a sandwich university. That is the Community half of the institutional-sale story NewsRadio tells in "Station Sale", so he appears at the exact point where each show threatens to take the building away from its ensemble. Personnel
Wayne FedermanRandy Stark in "Freaky Friday" (April 20, 1999).The Dad in "Emotional Consequences of Broadcast Television" (S6E13). Why it matters: the NewsRadio episode he appears in is the body-swap story that Community remakes deliberately as "Basic Human Anatomy", where Troy and Abed perform a Freaky Friday switch on purpose. His Greendale role is in the series finale, so his two appearances bracket the lineage at the NewsRadio original and at Community's last episode. Personnel

NewsRadio episodes that reach Greendale

NewsRadioCommunityWhat carries over
Super Karate Monkey Death Car
November 4, 1997
"Cooperative Polygraphy" (S5E4)An outsider puts the whole ensemble through a polygraph. Andrea, the efficiency expert, tests the WNYX staff, Joe steals a copy of the test and Lisa's criminal record comes out. Pierce's will orders a private inquest, and the study group must pass a polygraph to be cleared of his murder before anyone receives a bequest. Episode
Balloon
March 25, 1998
"Cooperative Polygraphy" (S5E4) and "Geothermal Escapism" (S5E5)A rich man fakes the voyage, and the next generation is made to do it for real. Mr. James announces he will circle the world in a hot-air balloon to prove his machismo to the other billionaires, then fakes the flight from a soundstage on the tenth floor, with Joe, his flight technician, running the deception and Dave sworn to secrecy. Pierce's will sets Troy the same voyage, the test Pierce's own father set him at 23, and Pierce says outright that he cheated it, so the will assigns someone to travel with Troy to verify that he does not. Significance: the inheritance is the fraud and its correction. Both shows tie wealth to a masculinity test the patron failed in private, both hand the technical work to the practical member of the ensemble, and Community closes the loop by making the younger man perform, under supervision, the journey the older man faked. Jimmy feeds Pierce in the premise map, and Joe feeds Troy. EpisodeInterpretation
Xmas Story
December 19, 1995
"Cooperative Polygraphy" (S5E4)The rich man's gifts skip the odd one out. Mr. James buys sports cars for everyone on the staff except Matthew, who gets tapes, and Pierce's will hands Abed, Matthew's descendant, nothing beyond the sperm every member receives. EpisodeInterpretation
Bill Moves On
September 23, 1998
"Cooperative Polygraphy" (S5E4)The ensemble comes back from a funeral for a character whose actor is gone. NewsRadio's staff return from Bill's memorial service after Phil Hartman's death, and the study group returns from Pierce's funeral after Chevy Chase left the show. Bill feeds Pierce in the premise map. EpisodePersonnel
The Real Deal
May 7, 1997
"Pillows and Blankets" (S3E14)A radio host brands his show with a rhyme on his own name. Bill hosts The Real Deal with Bill McNeal on WNYX, and Neil, now a campus radio DJ, signs off as "real Neil with pipes of steel." TV Tropes reads the sign-off as a shout-out to Bill's show. EpisodeInterpretation
Planbee
September 30, 1997
"Ladders" (S6E1)A hired outsider arrives to put the place in order. Mr. James brings in Andrea, an efficiency expert, to bring order to WNYX, and the Dean brings in Frankie as an "administrative consultant" after a roof collapses. Frankie proposes cutting classes such as Ladders. Both owners leave the room right after the introduction, Jimmy on a piranha joke and the Dean on a fake phone call. Episode
Rose Bowl
February 5, 1997
"App Development and Condiments" (S5E8)Coworkers grade each other. Dave agrees to let the staff review each other, and MeowMeowBeenz turns ranking classmates into a class war. Episode
Who's the Boss?
January 20 and February 3, 1998
"Competitive Wine Tasting" (S2E20)Both shows ask who the boss is. NewsRadio's two-parter makes Bill the boss to punish him and then puts Dave and Lisa to a staff vote, and Abed's class on Who's the Boss? ends with his proof that Angela was the boss. EpisodeInterpretation
Catherine Moves On
November 25, 1997
"Horror Fiction in Seven Spooky Steps" (S3E5)An episode built from each character's version of events. The staff offer their versions of how and why Catherine quit, colored by their own perceptions, and Britta has the study group tell scary stories to see how everyone reacts. EpisodeInterpretation
Our Fiftieth Episode
April 2, 1997
"Curriculum Unavailable" (S3E19)A member of the ensemble is headed for a mental institution. An argument over a traffic ticket gets Bill committed to a mental hospital, and Abed, given the choice between therapy and jail, goes with the whole group to a psychiatrist who decides he should be committed. Episode
Twins
March 12, 1997
"Remedial Chaos Theory" (S3E4)The oddball gets a double. Matthew's "identical twin" brother Andrew visits, played by Jon Stewart, and the darkest timeline produces Evil Abed. Why it matters: each show doubles the same seat, the socially unreadable member of the ensemble, and uses the double to show what that character would be without his restraints. The Community half was directed by Jeff Melman, the one person credited on both a Saved by the Bell production and a Community episode, so the device and the crew link arrive together. EpisodeInterpretation
Noise
October 21, 1998
"Lawnmower Maintenance and Postnatal Care" (S6E2)A gadget hooks the boss. Dave and Jimmy get addicted to Joe's white noise box, and the Dean gets lost in a virtual reality system until Jeff finds its inventor, Elroy, who recombines Troy and Abed on the shadows list. EpisodeInterpretation
Hair
February 9, 1999
"Debate 109" (S1E9)Hypnotism as a cure. Joe hypnotizes Jimmy to cure his fear of hippies, and Pierce hypnotizes Britta to stop her smoking. The Greendale Lineage page ties the same scene to the hidden messages of Saved by the Bell's "The Zack Tapes", so the scene has a parent in each older show. EpisodeInterpretation
Jail
November 4, 1998
"The First Chang Dynasty" (S3E21)A usurper takes the institution once its leader is locked away. Jimmy is arrested as the hijacker D. B. Cooper and Johnny Johnson replaces him, looking to make it permanent, and Chang kidnaps the Dean and swaps in a Doppeldeaner. Episode
One Community episode gathers five of them. Five older episodes meet in "Cooperative Polygraphy" (S5E4): NewsRadio's polygraph, its around-the-world test, the gifts that skip Matthew and Bill's memorial, plus Saved by the Bell's fight over a bequest. It is also the episode that finalizes Pierce's exit after Chevy Chase left the show. InterpretationProduction record

The build confirms 146 anchor phrases behind these 35 rows, from the NewsRadio and Community dialogue, the TV Tropes recaps, the Saved by the Bell Wiki and Wikipedia's episode lists, and it fails if a row loses its evidence on either side.

Five kinds of ancestry

A Greendale character can take personality from one older show, a relationship position from another, a seasonal job from a third, and grow through several roles over the run. The show also keeps shadows of its own characters.

Personality ancestry

Who a character resembles across the whole run.

Example: Buffy to Britta

Relationship ancestry

A position held opposite one other character.

Example: Angel and Buffy to Jeff and Annie, and Dave and Lisa to the same pair

Seasonal or functional slot

A job in the story that changes hands from season to season.

Example: Buffy's rotating Big Bads to Chang

Developmental ancestry

One character moving through several older roles over time.

Example: Troy, from A.C. Slater to Joe Garrelli, and Annie, from Cordelia to Willow to Dark Willow and from Jessie Spano to Lisa Miller to Frankie Dart

Shadow

An alternate, suppressed, future or replacement version of another character.

Example: Annie Kim to Annie Edison

Troy's line

NewsRadio pairs

NewsRadioGreendaleEvidence
Dave and LisaJeff and BrittaThe concealed workplace relationship travels here. Dave and Lisa keep the affair off the record, "what if we just decided to keep this a secret," then apologize to the staff "for lying about our affair," and Community hides its own version until the reveal that "Jeff and Britta are having secret sex" [S02E21:L77]. Significance: the secrecy is the inherited machine, not the couple. It carries the same costs in both shows, a colleague who learns first, a staff that feels lied to, and a pairing that never becomes public. Lisa's own line runs to Annie through competence, achievement and rule-breaking for grades, and Dave's runs to Jeff, so one NewsRadio pair feeds three Greendale characters along two different routes. EpisodeInterpretation
Joe and MatthewTroy and AbedJoe teaches Matthew gambling until double or nothing leaves him owing $5,120, then $10,240 ("In Through the Out Door", S2E13). In "Space" (May 21, 1997) Joe triggers the self-destruct and Matthew kicks out the life-support cord, and in "The Injury" (June 5, 1997) the two compete to grab a coffee cup off a hallway light fixture until Matthew hurts his hand. Joe casts Matthew "to play the role of Alien" in a scripted show for his 24-hour break room Internet-cam ("Apartment", S5E12), trains him in Joe-jitsu ("Padded Suit", S5E19), and with Beth stages a mock job interview for him that turns into a pretend NASA interview ("Retirement", S5E21). Emily St. James's February 5, 2010 AV Club review of Community's "Romantic Expressionism" called Joe and Matthew "sort of the proto Abed and Troy", pairing the two duos without matching individuals. EpisodePublished review
Jimmy and MatthewThe Dean's cell"Freaky Friday" (S5E20, April 20, 1999) has Jimmy and Matthew switch jobs for a day, and the map's Dean cell averages Jimmy at 4 with Matthew at 3.5. EpisodeInterpretation
Catherine and JoeOpenTheir on-screen flirtation implies a Shirley and Troy counterpart, and the map doesn't place one yet. EpisodeInterpretation
Jimmy and AndreaThe Dean and FrankieThe owner brings an outside woman into a failing workplace and walks out as soon as the staff start asking questions. Jimmy exits on a piranha joke in "Planbee" (S4E2), and the Dean fakes a phone call in "Ladders" (S6E1). The row records a scene role, and the cast scores stay as declared. EpisodeInterpretation
Andrea, Lisa and MatthewFrankie, Annie and AbedAndrea fires Matthew and gives Lisa Dave's job across S4E2 to S4E5. Frankie wins Abed over and leaves after dismissing him in S6E1, and she later tells Annie to get away from Jeff in S6E12. EpisodeInterpretation
Troy as Joe and Abed as Matthew already score 5. The NewsRadio cells with room are the Dean at 3.56 and Chang at 2.13 after the reuse penalty.

Buffy, corrected

Britta is Buffy. Annie is Willow, starting as Cordelia in the rivalry with Britta, and the slow reveal is Annie as Dark Willow. Jeff starts as Angel in the forbidden romance with Annie and becomes Spike later, so those stages count in sequence. Chang holds the rotating Big Bad slot because his role changes the same way.

Community Fit comes to 4.53, and the one-to-one match is also 4.53 with no empty slots, since relationship positions don't count as a second use. Cordelia is rated 5 as Annie's first stage, the same rating as Angel and Spike for Jeff. That puts Buffy's Source Fit at 4.66 and its working index at 92, tied for third with Arrested Development.

Shadows and succession

Community keeps doubles, futures and replacements of its own characters. Late regulars count on the Greendale side as a succession layer, so NewsRadio's Max Lewis matches Hickey, who arrives in Pierce's old slot in season 5.

Annie Kim to Annie Edison

Alternate, then rival, then replacement

Introduced in "Geography of Global Conflict" (S3E2) as Annie's multicultural evil twin with the same high school GPA, back in "History 101" (S4E1), and in "Queer Studies and Advanced Waxing" (S6E4) she replaces Annie as Daniel in The Karate Kid.

Episode

Beth and Sandi to Britta, Annie and Annie Kim

Distributed rivalry

NewsRadio builds the doubling machine first. Beth says Sandi stole her high school sweetheart, "not to mention my hairstyle, my mannerisms, and my eclectic, some say daring, sense of style," calls her "a copycat" who "wants to be me," and tests it by feigning interest in Matthew to see whether Sandi follows. Community splits that machine in two. The romantic half runs between Britta and Annie, who follow each other through Vaughn and Jeff. The academic half runs between Annie and Annie Kim, the "multicultural evil twin" with the same high school GPA who eventually replaces her outright. Significance: this gives Annie Kim an older television ancestor for the exact job she performs, and it shows one older mechanism arriving in two halves rather than one character, which is the model this map argues.

EpisodeInterpretation

Pierce to Jeff

Future shadow

The ending Jeff fears if vanity, manipulation and the fear of becoming irrelevant win out.

Interpretation

Frankie to Annie

Professional endpoint

Frankie arrives as an administrative consultant in "Ladders" (S6E1) and already holds the list of problems Annie chased through season five. Andrea's arc on NewsRadio is the older model, where an efficiency review hands Lisa her boss's job. In "Basic Crisis Room Decorum" (S6E3) Frankie calls her apparent psychic streak an illusion created by being extremely prepared, and in the same scene she is told she sounds like Jeff, answers that Jeff said she sounds like Abed, and wonders whether Britta hears Chang. The Greendale Lineage page carries the full line.

EpisodeInterpretation

Hickey to Pierce's slot

Succession

Buzz Hickey arrives in season 5 after Pierce leaves and appears in 11 of its 13 episodes. On NewsRadio, Max Lewis arrives in season 5 as Bill McNeal's replacement, so Max's reverse match is Hickey, rated 5 for ensemble function, with personality closer to 2.5 to 3.

EpisodeInterpretation

Elroy to Troy and Abed

Recombination

Elroy and Jeff pull the Dean out of a 90s VR system in "Lawnmower Maintenance and Postnatal Care" (S6E2), and Elroy and Abed find a birds' nest in the router in S6E4.

EpisodeInterpretation

Chang to The series itself

Role shadow

A character whose job changes whenever Greendale needs a new one, from teacher to student, guard, ruler, actor and tolerated outsider.

The one-to-one match lets each source character fill at most one Greendale slot and each slot take one character, so it checks concentration on both sides and has no column-order effect. It uses only the names in the map, so a slot with no second candidate counts zero. On this check Arrested Development leads, Buffy is second, South Park third and NewsRadio fourth, and It's Always Sunny, Scrubs and Saved by the Bell fall furthest because their maps reuse characters.
Victorious is a chronology comparison. It premiered on March 27, 2010, after Community's pilot, so it can't explain the 2009 designs. The source ranking's figure for it is 89.5, which shows the index also picks up a later school sitcom with a similar ensemble shape. Its map isn't on this page, so that figure predates the order-free tie rule.

Casting and TV knowledge inside Greendale

Each row gives the scene, then the layer outside it: the actor's other roles, the network, the production, or a later callback.

WhereIn the sceneThe outside layer
S1E4 "Social Psychology"Abed casts Annie and himself as Chandler and Phoebe, a pair that never really had stories together.Abed reads his own friendship through Friends, NBC's biggest sitcom, and the map later sends Phoebe to Abed. EpisodeInterpretation
S1E9 "Debate 109"Pierce's hypnotherapy to stop Britta smoking uses gorilla as the wake word, and Britta turns out to be pretending.Season 6 comes back to the word through Honda's guerrilla marketing, a guerrilla spelling joke, and Britta calling herself a Level 7 Susceptible. EpisodeInterpretation
S1E12 "Comparative Religion"Jeff fights Mike, a bully played by Anthony Michael Hall.Hall played the brain in The Breakfast Club, the film the pilot uses to frame the study group, so eleven episodes later the casting flips his archetype. EpisodePersonnelInterpretation
S1E13 "Investigative Journalism"Jeff plays Hawkeye, Abed asks to be called Radar, calls it a character reboot and gives Jeff a pep talk on leadership, and Jeff turns out never to have watched M*A*S*H.The episode itself supplies two cells of the map, Hawkeye to Jeff and Radar to Abed, and both score 5. EpisodeInterpretation
S1E17 "Physical Education"Abed builds his Jeff impression from Dick Van Dyke, Sam Malone, Zach Braff and Hilary Swank, then practices seduction on Annie as Don Draper.Alison Brie was playing Trudy Campbell on Mad Men, Abed repeats the Draper impression in S3E19 with Annie visibly affected, and the Jeff recipe names two map cells, Sam Malone and J.D. EpisodePersonnelInterpretation
S2E7 "Aerodynamics of Gender"Andy Dick turns up as the little man inside Pierce's miniature spy plane.Andy Dick played Matthew on NewsRadio, and Emily St. James's AV Club review said the cameo continued her "Community is a secret remake of Newsradio" theory, which she wrote makes no sense and comforts her at night. Published reviewPersonnel
S2E8 "Cooperative Calligraphy"Abed calls the missing-pen lockdown a bottle episode and says he hates them, and Jeff cancels his date by phone because he is doing a bottle episode.The group uses a production term for a cheap one-room episode as everyday vocabulary, inside an episode built that way. EpisodeInterpretation
S2E12 "Asian Population Studies"Jeff compliments Andre's sweater, and Andre says his dad gave it to him.Malcolm-Jamal Warner played Theo Huxtable on The Cosby Show, where his TV father's sweaters were the famous costume. EpisodePersonnel
S2E16 "Intermediate Documentary Filmmaking"Britta offers LeVar Burton her $261 to change his flight so Troy gets more time with him, and LeVar calls her a very generous friend who is really stupid with her money.LeVar plays himself and asks whether he is known from Star Trek or Reading Rainbow. His read on Britta matches S1E3, where she paid for Abed's film class and Shirley praised her follow-through, a scene LeVar never saw. EpisodePersonnelInterpretation
S2E19 "Critical Film Studies"Abed tells Jeff he panicked as a background extra on the Cougar Town set, got through the take by becoming a local he named Chad, and pooped his pants when the scene ended.Danny Pudi then turns up in a real Cougar Town episode, Busy Philipps and Dan Byrd appear in Community's season 2 finale, and Bill Lawrence set it up. Lawrence created Scrubs, number two on the index. EpisodeProduction recordPersonnel
S2E20 "Competitive Wine Tasting"Garrity excuses an easy resolution by telling the class they are actors and the story matters less than their time in the spotlight, and Abed takes a class on Who's the Boss and answers its central question.Kevin Corrigan's drama teacher is back from S2E9, and his speech says out loud what a crowded episode does with its last minutes.

S2E21 "Paradigms of Human Memory"In a clip-show flashback, Abed answers Jeff's prediction that The Cape will last three weeks with six seasons and a movie.The Cape was a one-season NBC show. The line became the fan slogan, NBCUniversal tied it to the Peacock movie, and Cape regular Keith David later narrates Pillows and Blankets and joins the cast as Elroy. EpisodeProduction recordPersonnel
S2E23 "A Fistful of Paintballs"Abed reads the Black Rider as network TV good-looking.Josh Holloway was Sawyer on Lost, so Abed describes a casting category as something visible inside Greendale. EpisodePersonnelInterpretation
S3E12 "Contemporary Impressionists"Abed owes three grand to a celebrity impersonator agency, so the group takes impersonator jobs to pay it off.The agency boss is a French Stewart look-alike played by French Stewart, Harry on 3rd Rock from the Sun, another show on the index. EpisodePersonnel
S3E13 "Digital Exploration of Interior Design"A student named Subway enrolls so Subway can open in the cafeteria.Subway paid for the placement, and director Dan Eckman said they had complete freedom in how to put the brand in the story. Season 6 brings Subway back as Rick and warns Britta never to say the name without compensation. EpisodeProduction record
S3E14 "Pillows and Blankets"Keith David narrates the pillow and blanket war as a Ken Burns documentary, and Jeff asks him whether he was in The Cape.He says no. He was a Cape regular, and three seasons later he joins the cast as Elroy, in the same world that once recognized him as Keith David. EpisodePersonnelInterpretation
S3E17 "Basic Lupine Urology"The yam murder plays as Law and Order, and Professor Kane tells Jeff, "A man's gotta have a code."Kane is Michael K. Williams, whose code line echoes Omar on The Wire, and the botanist is Leslie Hendrix, Law and Order's medical examiner. EpisodePersonnel
S5E1 "Repilot"Abed explains repiloting and notes Zach Braff was in only the first six episodes of Scrubs season 9, and Troy is furious at Braff for leaving.Donald Glover leaves after five episodes that season. The same episode asks how Britta became the group's airhead, tells Troy his entire identity has been consumed by his relationship with another man, and names season 4 the gas leak year. Scrubs' Travis Schuldt and Eliza Coupe had already played Greendale roles, Subway in S3E13 and Special Agent Robin Vohlers in S2E17. EpisodePersonnelInterpretation
S5E6 and S6E4Paget Brewster plays Debra Chambers, the head of I.T., in S5E6, then Frankie, and in S6E4 Frankie complains that her emails to the IT lady bounce back in Aramaic and that calls end in a whistle that makes her nose bleed.TV Tropes reads the joke as the show acknowledging that one actress played both women, and nobody on screen names Brewster. EpisodePersonnelInterpretation
S6E6 "Basic Email Security"When Frankie and Elroy learn Chang used to teach at Greendale, Chang says he hasn't been well utilized since.The line works as a character complaint and as a verdict on how the show used Chang after his Spanish teacher start. EpisodeInterpretation
S6E7 "Advanced Safety Features"Rick, the former Subway, returns to guerrilla market Honda, the Dean is a Level 7 Susceptible, Britta calls herself one about Rick, and when Britta names what Rick is doing he says she isn't allowed to know that.The episode is itself paid Honda placement, so Rick explains to Britta what the episode is doing to its viewers, and the guerrilla spelling joke calls back to Britta's S1E9 gorilla wake word. EpisodeProduction recordInterpretation
Victorious, "Helen Back Again"Yvette Nicole Brown plays Helen in her only Victorious episode.Helen is the character Brown played on Drake and Josh, carried onto a Nickelodeon show that aired alongside Community. EpisodePersonnel
Pilot and VictoriousThe pilot has Abed comparing the study group to The Breakfast Club and Britta answering that they are in a library, and Dan Harmon's pilot script is dated January 28, 2009.Victorious aired its Breakfast Club parody, The Breakfast Bunch, on January 28, 2012, three years to the day after the script's date. EpisodeProduction record
Victorious, "April Fools' Blank" (2012)Jade speaks her own stage directions, a director hurries André to the next scene by calling his actor's real first name, Leon, and Rex freezes the frame to announce the commercial break.BuddyTV's 2012 review said the April Fools episodes of Victorious and iCarly felt more like NBC's Community than typical kids' TV.

Working notes

Transcript check, September 15, 2026

Every row labeled Episode, and every lineage row, was checked against the Community dialogue for all 110 episodes, the speaker-labeled transcripts, the TV Tropes recaps, the NewsRadio dialogue, saved wiki pages and Wikipedia's episode lists. The build confirms 270 anchor phrases in 119 files across 77 rows, and it fails if a checked row loses its anchor or a phrase stops matching its file.

PlanbeeThe Dean says "I have brought her on as an administrative consultant" in "Ladders." The CFO wording comes from TVmaze's episode summary.

Held up under the check: Annie Kim replacing Annie as Daniel, Jeff asking the narrator about The Cape, Abed's network TV line, Britta's Level 7 remark, the guerrilla spelling joke, Garrity's return from S2E9, Hickey in eleven of thirteen episodes, Matthew kicking the life-support cord, and Harmon's 30 Rock undercut.

How the working index is computed

Community Fit averages the nine Greendale slots. A cell with several approved names averages them. A source character used in more than one slot keeps its strongest use at full value, its second at 95 percent and its third at 85 percent. Tied uses share the average of their multipliers, so column order has no effect, and relationship positions don't count as a second use.

Source Fit averages each declared regular's best Greendale match on a separate reverse pass. Late Greendale regulars count through the succession layer, as Hickey does for NewsRadio's Max Lewis, and stage calls count at their stated rating, as Cordelia does for Buffy.

Working index is the harmonic mean of the two, scaled to 100 and rounded here.

Recomputing from the full map reproduces every published Community Fit score except Scrubs, which the tie rule moves from 4.62 to 4.61, and its index stays 93. Buffy's published 4.31 came from its map before the correction, which still reproduces it, and the corrected mapping replaces that row.

Each index is rounded once, from its exact harmonic mean, using Source Fit from the reverse roster where it is known. That puts Cheers at 80 from 80.47, where rounding the published 80.5 gave 81.

M*A*S*H's B.J., Mulcahy and Henry and Gilmore Girls' Luke, Sookie and Richard have no rating in the map, and South Park's four boys and How I Met Your Mother's five leads average above their published Source Fit, so those four reverse rosters stay provisional until each regular's rating is exposed.

The full map with cell math

Each cell shows names, Match strength on a five-point scale, any reuse penalty, and the value the working index uses. Match strength measures how strongly a source character fills a Greendale slot, a separate question from how well evidenced the claim is. Darker cells score higher.

Settled questions
  • Cordelia. Rated 5 as Annie's first stage, rivalling Britta, the same rating as Angel and Spike for Jeff.
  • Buffy. Back in the working index at 92, tied for third with Arrested Development, with Source Fit 4.66.
  • Relationship positions. They describe a pairing and don't count as a second use of a character, so Buffy's Community Fit is 4.53.
  • Tie rule. Tied uses of one character share the average reuse multiplier, so column order has no effect. Scrubs moves from 4.62 to 4.61 and stays at 93.
  • Max Lewis. On NewsRadio's roster through the succession match to Hickey, rated 5 for ensemble function, and NewsRadio's Source Fit stays 4.94.
  • Rounding. Each index is rounded once, from its exact value, so Cheers reads 80 from its exact 80.47 rather than rounding twice through 80.5.
  • Reverse concentration. The one-to-one match is the concentration check on both sides, since no character fills two slots and no slot takes two characters.
  • Reverse ratings. Exposed for fifteen rosters, every one the published scores pin down.
  • Documentation. The AV Club line calling Joe and Matthew the proto Abed and Troy, "The Injury", both April Fools' Blank details and the review comparing Victorious and iCarly to Community now carry sources.
  • NASA interview plot. Found in the dialogue for "Retirement" (S5E21): Joe and Beth stage a mock job interview for Matthew that turns into a pretend NASA interview.
  • Matthew's debt. The dialogue for "In Through the Out Door" has $5,120, then $10,240, which replaces the wiki's $20,000.
  • Black Rider line. The S2E23 dialogue reads network TV good-looking.
  • Episode numbering. Space and The Injury are cited by air date, since NBC held The Injury until after the season 3 finale.
  • Proto pair review. Emily St. James wrote it on February 5, 2010, and her sentence pairs the two duos without matching individuals.
Still open
  • Four shows' reverse ratings. M*A*S*H, South Park, Gilmore Girls and How I Met Your Mother still need each regular's reverse rating exposed, so those rosters stay provisional.
  • Catherine and Joe. No Shirley and Troy counterpart is placed.
