Summary: The study group travels through time and space.
Comments: The group becomes the Tenth Doctor's new companions. This can only end hilariously for all.
Seconded by Doctor Nemesis: It's beautifully done, everyone's perfectly in character and it's one of those genius ideas you can't believe no one else has had yet. And without wanting to spoil anything, it even fits in paintball! Paintball!
Comments: Not only are the characters perfectly written, but the dream sequences play with the group dynamics (and genders) hilariously. It's worth reading for the Black Rider as Zoe in the Firefly pastiche alone.
Summary: Abed discovers the reason he's always been different. Plus: fish stick jenga, innappropriate Pierceness, zombiehood and giant cookies!
Comments: This is insanely perfect for all lovers of Abed. All the characters read EXACTLY like they do on the show, and there are subtle crossovers with "Firefly" and other shows. There is angst involving mental health issues but also a wealth of quick, charm, and sweetness.
Summary: In which Troy decides what he wants to be when he grows up, battles the ice cube of sadness, bakes some cookies, and figures some things out about feelings.
Comments: This is such a sweet, funny, good-natured, and overall delightful (in that very Community-like way) read that I can't help but urge everyone to give it a look whether they ship Troy/Abed or not. Though Troy and Abed are obviously the main features, the entire study group is present in some form throughout the story, and written so true to character that you can hear their voices as you read. Lots of funny little one-liners, and a seamless integration of deeper ideas about adulthood and responsibility into the developing relationship.
Summary: Abed gets his shoulder dislocated and has to walk Troy through first-aid procedures. Shameless fluff!
Comments: This is a fanfic I wrote. It contains Troy/Abed. No sex scenes, but a very cute kiss. I'm rather impressed with it myself. Although I've checked it over a couple million times, it never gets old!
Summary: Britta's apartment gets rats; she and Jeff end up as roommates.
Comments: This is overall wonderful. The author has a good grasp on every single character. When the rest of the study group appears, they're written well and add to the story, but it's truly the characterization of Jeff and Britta that not only stays true to how they are on the show, but adds depth. The writing is funny , and the chemistry between them is written perfectly.
Seconded by Cettin. This is absolutely brilliant. The characterization is spot-fucking-on, and the chemistry's wonderful.
Summary: Jeff and Britta's reactions to the events of 'Modern Warfare'... as recorded by Professor Ian Duncan.
Comments: Having Professor Duncan narrate a what-if scenario is one of the best ideas I've seen played out in Community fic, and the story itself is hysterical. It also helps that Prof. Duncan's characterization is spot-on.
Summary: Wherein metaphors need to be changed, Abed has trouble thinking right when Troy is touching him, Abed takes a punch, and there are references to Spiderman.
Comments: There are some bits of characterization that don't quite ring true to me, but over all I think it's characterization is very solid. Best of all is how the author maps out Abed's thought processes in a way that seemed completely believable to me, showing Abed as not slow or one dimensional as usually happens to CloudCuckooLanders in fic, but just...really weird. The fic also strikes a lovely balance between Troy's geekiness and normal-guy-ness.
Pairing(s): Troy/Abed, with a side of Jeff/Annie and Britta/Subway
Summary: In which Troy has a revelation, the Toyota Agony gets a lot of mileage, drama is resolved, Evil Troy makes an appearance, the Air Conditioning cult gets excited, and Annie's Boobs are immortalized on a pinball machine.
Comments: Picks up a few months after the end of Season 3, with pretty spectacular reference to all the canon. Beautifully in-character, and so cute it melted my brain.
