You didn’t specify a fandom, so I’ll just choose randomly based on what I’m thinking about! (which right now likely means angsting about OUAT and Mass Effect, just as a warning…)
C - A pairing you have never liked and probably never will
Captain Swan (Hook and Emma Swan), from OUAT. He’s too slimy and deceptive to be likable. Pitiable, yes, but not likable.
D - A pairing you wish you liked but just can’t
Red Beauty (Ruby/Red and Belle), also from OUAT. At this point, anything I’d’ve liked about them being friends has been crushed, CRUSHED I TELL YOU. Especially when Ruby outright lied to her and then sat by and let that horrible orderly drug Belle again instead of stopping her from hurting her friend—okay I have to stop before I rant for 20 minutes. XD
I - Has Tumblr caused you to stop liking any fandoms; if so, which and why?
Yeah, kinda…the MLP fandom is what I’m thinking about with this one. Mostly because people are more free with their emotions (and therefore with bigotry) on the internet, and because Tumblr lets a person meet/hear about many more people than in-person groups do. As a result, a few douchebags (and many of their supporters) have made me want to avoid the MLP fandom in general. But I still follow many fans of the show, because they are sweet and awesome peeps. c:
L - Your favorite fanartist/author gives you one request, what do you ask for?
This may sound self-centered, but…probably a portrait of me and/or my friends, like this one! I just really love seeing what other people think we’d look like in their style. (If it’s not a commission, I’m more likely to ask for a picture of an OTP or fandom-related thing, because then the artist can share their work with a wider audience. :D)
N - Your favorite fanfiction or fanauthor
THAT’S NOT FAIR— Okay, I’ll just pick some random ones because I can’t choose between all my lovelies, so please don’t be offended if you’re not on this list. My brain is not the best at remembering. XD So. Here’s a random list (rearranged to be alphabetical since I can’t choose just one fave): conquerorwurm, Dal Niente, Dani Kin, Hunger4righteousness, Memlu (The Croc Shop), MomoOfficial, Nym, quondam, rufeepeach, servantofclio, Scarlet-Frost, tarysande, Vaniterra, wafflestories, writetherest…(+ lots more)
R - A pairing you ship that you don’t think anyone else ships
Samantha Traynor and Tali, from Mass Effect. They’d be so cute and shy and nerdy with each other, plus they both have cute accents. What’s not to love???
X - 3 OTPs from 3 different fandoms
These aren’t exclusive; I’m a huge multi-shipper!
OUAT: Swan Queen (Regina/Emma; tied with Rumbelle, Rumpel/Belle, and Sleeping Warrior, Mulan/Aurora).
Mass Effect: Shakarian (Shepard/Garrus)
Adventure Time: Bubbline (Princess Bubblegum/Marceline)
