Thanks for offering to write in one or more of my requested fandoms! If you want a better idea of what I like, you can check out my general fic kinks and squicks post. Particular to Purim Gifts, I've listed my favorite pairings in the fandom details below, but all three of these fandoms are ones in which I'm very happy to receive gen fic about any of my favorite characters. And do have fun with whatever you decide to write; I'm sure I'll love it!

Inception RPF
So, when I say I want Inception RPF, what I really mean is I want Joseph Gordon-Levitt fic. I do prefer his being written as gay (Tom Hardy/JGL is particularly nice), but you should also feel free to write gen in which his sexuality isn't mentioned if that's your preference. And if you offered this fandom in the hopes of writing one of the Inception actresses, then Ellen Page gen or femslash is a more than acceptable alternative.

Suits
I love Jessica and Donna best, though Rachel and Scotty are also awesome, and I wouldn't say no to a story or two about the mysterious Vanessa. My favorite pairings, etc., are Jessica/Mike, Jessica/Mike/Harvey, Donna/Rachel, Jessica/Donna/Harvey, and Jessica/Donna. Just, please, no Trevor, Jenny, or Louis, and no Mike/Harvey (except as part of a Jessica/Mike/Harvey threesome, if you're going that route).

X-Men: First Class
My favorite eligible characters are Erik, Angel, and Moira. If you're interested in writing shipfic, I'd love any of: Erik/Charles/Angel, Erik/Moira, Angel/Raven, Alex/Darwin/Angel. This fandom is one where I really don't mind if you break my heart--angst; heavy depictions of racism, homophobia, sexism, and/or anti-Semitism; and ambiguous or downright unhappy endings are all fine by me. Which isn't to say that you have to write angsty or serious fic; happy or romantic fluff is equally welcome! Just, the option is there if you want it.
