Maim/murder/death: 95% of the time I'll be up for plotting involving all three of these. Just check with me first!
Kissing: She probably won't react well unless she's very close to the character trying, or she's on a downward spiral/feeling particularly emotionally vulnerable. Romantic kisses are actually less likely to get an angry or confused response than purely platonic ones are, though it's possible she still won't reciprocate.
Hugging: Again, unless she's close to someone or in an vulnerable enough state, she'll avoid touch. If she is close enough to someone that she's willing to be affectionate with, though, she'll be willing to do it quite a bit.
Badtouch: She will eat your soul. Seriously though, sex isn't something that she values very highly-- she isn't a virgin (having had sex with a girl before; she's never had sex with a guy), but while she isn't asexual and she doesn't hate sex, it doesn't factor highly onto her list of things that she likes to do. She's capable of enjoying it and she does think it feels good, but ultimately, she finds it awkward and embarrassing. While you have my full OOC permission to go for it if it's IC for your character, Azula may be quick to label your character as a horrible pervert unless there's a lot development-- and even if there is, she won't necessarily reciprocate.
Threadhopping: Sure, I'm completely fine with it as long as you don't hop into a locked conversation or log (unless your character would logically stumble upon the scene or you ask permission first).
Fourthwalling: Go for it. She already knows it all. Anyone who tries to tell her that she's actually a fictional character (as opposed to someone who just happens to be considered fictional on some worlds, that is) will get a long lecture on her understanding of the multiverse, though.
Backdating: I'll continue any old conversation/thread/log, no matter how long its been since the last comment (in other words, if you dropped a thread two months ago and now want to continue it, go ahead and I'll reply!). The same goes for replying to old entries- though obviously, I'll backdate any responses. The only exception to this would be if you replied to an entry from before your character was in the game, because it wouldn't be following continuity.
