Best FF in Which We Learn That Even Wizards Can't Resist Choosing the Bad Boy Instead of the Good Boy: Waterworld, by rhoddlet. Harry Potter, Harry/Ron and Harry/Draco. It's sort of sad to see Harry Potter doing something so regularly discussed in Cosmopolitan, but at the same time it proves that magic is no protection against human frailty. Or stupidity. The greatest thing about this story, though, is the way it's told. In FF, a relationship is usually seen through the eyes of one or both of the participants; Rhoddlet does a fantastic job of showing us everything we need to know (or want to know, in my case) through an uninvolved, though far from disinterested, party.
Best FF in Which We Learn That All Women Know Exactly How to Run a Threesome: Shameless, by penknife. Teen Titans, Dick/Donna/Kory. They're just ordinary teen-agers. With superpowers. Having a threesome. And issues. Which, provided you're willing to count world-beating moodiness as a superpower, really pretty much sums up adolescence, now that I think about it. The surprising thing about this story is that it's the guy who's hesitant about having a threesome with two girls. Although, really, given that the guy in question is Dick, maybe I'm not so surprised after all.
Best FF Featuring a Prison Setting That Does Not Involve Hot Male/Male Prisoner Sex: In Dreams, by Elizabeth*. X-Men movies, Rogue, Xavier/Magneto. This is almost gen, which is the only way I could handle this unusual threesome; I mean, I don't want to read explicit Xavier/Magneto!Rogue. Ew. But I do love stories that look at what it must be like for the movie Rogue to be Xavier's student and have Magneto's memories. 'Cause, lordy, that's the perfect way to work up a real head full of crazy, having a supervillain's memories of happy times with your headmaster and parental figure. And it's not like Rogue needs more craziness in that stripy head of hers.
Best FF That Could Inspire a Whole New Edition of "Everything I Needed to Know I Learned In Kindergarten": Six to Eight Months, by cherryice. Ocean's 11, Tess/Rusty, Tess/Danny, Danny/Rusty. Look, I didn't care for Tess much either. And I needed a lot of persuading, not to mention fortitude, to buy Tess/Rusty. But you know what? Cherry Ice sold me on it; it totally works. Oh, and the things you learned in kindergarten that are crucial in this story? Well, let's start with "sharing is good." Also important: "some things come in pairs, and it just doesn't work have one without the other" and "love me, love my friends." No, wait, sorry. That last one isn't something you learn in kindergarten; it's something you learn in Richard Curtis movies. Still, this is FF that incorporates a lot of moral lessons. But somehow I don't think it's going to make Robert Fulgham proud.
