so since u guys liked that i did this with remedial chaos theory i will now also be doing this for epidemiology.
the most incredible thing about this episode is that it is in fact Not merely an homage like most concept episodes are; it actually happens. a zombie epidemic For Real takes place at greendale. it's not a gimmick or a game or a way to frame the plot. the actual conflict is derived from the fact that people are zombies and the study group need to outrun them/turn them back. how often can you say that a sitcom incorporates a storyline like this and sincerely pulls it off? never.
the emotional tension in this episode is framed around troy/abed/jeff and the dichotomy of being a nerd vs. being cool, which respectively get attributed the qualities of caring about the people around you who have turned into zombies or wanting to run and escape from the zombies without trying to help. abed and jeff's costumes are both pointed out in the beginning receiving clear denotations of 'lame' and 'too cool to care' and therefore their positions in the conflict are cemented. the episode has a push-pull with troy being the moving factor, having to decide what he thinks is most important. he gets swayed in the beginning by two girls rejecting him over his costume and jeff mentioning how expensive his suit is. he changes from his ripley costume into a 'sexy dracula'. abed spends the whole episode trying to get troy back to his side, even saying "what defines a nerd? committing to an awesome halloween costume with your best friend?" troy is eventually 'turned back' into his nerdy self (perhaps a zombie metaphor itself, keeping in tone with the theme of the episode) because jeff cares more about his suit getting dirty than surviving the herd of zombies.
a crucial part of the episode is that it is soundtracked by abba music playing from the dean's playlist. now, who would i be if i didn't investigate significant music choices connected to scenes? first up and probably the most important one: s.o.s. is used in the background of a scene where abed confronts troy about changing costumes. troy insults him and walks away. the lyrics are: 'you seemed so far away, though you were standing near. you made me feel alive, but something died, i fear. i really tried to make it up, i wish I understood. what happened to our love? it used to be so good.' next; gimme gimme gimme plays right before the scene where chang and shirley hook up. another insane choice is at the end when troy is fighting the zombies. the whole sequence has mamma mia playing in the background Faintly. then when troy eventually gets to abed and has to fight him, the music comes in much louder with the lyrics: 'here i go again, my, my, how can i resist you?', which i think fits perfectly. the ending song fernando has the lyrics 'there was something in the air that night', both referencing the thermostat changing the zombies back and the fact that it was just an incredibly weird fucking night.
troy is dressed as ellen ripley and also kind of acts as the ripley of this episode. his journey in this as being the sole survivor and the one to eventually save greendale adheres to a common science fiction model where a life-threatening force is faced against the protagonists and they fall off in degrees, resulting in one person being left to mend everything. here specifically, it seems to mirror ripley's journey in alien (1979) as it starts with a crew that eventually gets cut down leaving only her. i thought that was really cool.
more alien tidbits, but the jumping cat scene is also inspired by it. jones the cat is an imporant figure in the first alien movie. in various scenes, members of the crew will go looking for him, then get ambushed by the titular alien and subsequently killed. it is a minor homage to the movie through yet another subtle reference. the bit is also parodying jumpscares in horror movies in general, and how they are used to cheaply amplify the tension. anyways, it's quite the multilayered joke because it also really works out of context as a bizarre comedic moment.
troy and abed's scene in the basement pays homage to princess leia and han solo's scene in the empire strikes back. the conversation in the film takes place just before han is frozen alive in carbonite by darth vader. not knowing if he’ll survive, he kisses leia, only to be torn away from her by stormtroopers. she says 'i love you,' and as he descends into chamber, han replies, 'i know.' an undeniably romantic moment, maybe one of the most memorable ones ever, is applied to troy and abed who have held reign over the emotional core of the plot for the entire episode. it's pretty special that such an iconic moment is given to them, i feel like the creators of the show wouldn't just do this sparingly. it also perfectly resolves their conflict as troy makes such a vulnerable statement and abed assuring him that he already knew, validating their bond once again.
more on troy and abed, it is pretty amazing realizing the emotional implications tied to how dire the situation was. everyone in this episode was under the direct threat of Not Surviving, and still abed sacrificed himself for troy. he knew this was for real. he couldn't be sure if they were going to make it. but i think he had enough faith in troy to aid in his escape. it's very touching. further, it's incredible that troy is willing to fight all the zombies (all his friends) but when it comes time to punch abed, he refuses to do it. he's struck by the force of their friendship, mumbling 'we're friends' defeated before eventually succumbing to his bite.
troy saving the school by controlling the temperature; nicely setting up his further plot with the ac repair school.
him being the one to escape and abed saying 'be the first black man to make it to the end' subverts the common horror trope of 'black dude dies first'. a playful way of keeping up with the horror movie theme of the episode.
also ironically this episode, which features the song mamma mia by abba, sets up a plotline in season two about shirley not knowing who the father of her new baby is, which is functionally the plot of the movie mamma mia!, a musical based on abba's music. probably a coincidence but a pretty funny one.
at the end when the army arrives, they ask the dean about witnesses. when he says he is the only witness, one of the guards reaches into his jacket, suggesting that he's pulling a gun intended to kill the dean and get rid of the witness. when they notice everyone in the school is still alive, they abandon this plan and go for 'scenario b'. kind of dark but i laugh every time that scene happens.
anyways that's all i could pull from my brain crevices for now. this episode is a genuine masterpiece, it will never ever get old and will remain to be one of the most unique sitcom episodes ever created.
