No real meat to it, but it's there. ^-^ Left you room for leaving or continuing the conversation, time-skip or no. Up to youuuu. I'm about to edit something though, so I can use it later for smalltalk between them. Heh.
So I actually ended up adding like two paragraphs. XD I've decided something, and decided to hint at it with that last post there. I think I'm going to have Praxis develop dissociative identity disorder, but like...a 'minor' case, if that makes sense. DID, or multiple personality disorder, often develops to cope with certain parts of your life, e.g. Praxis losing his family, his mom stabbing him in the hand, then him having to kill her, and now meeting this girl that's changing his life. it sounds really uninspired and trite to want to develop this cliche disorder, but hear me out, 'cause I've got some really good reasons and ways to use it. But before the reasons, you should know I don't mean in a way that is so bad he is all messed up all the time, just in a way that supports his Primal State ability, which is part of the reason I want to have him develop it. The main reason, though, is 'cause of the Mom thing, and when he meets Aruna his life is changing so to cope he wants to be more normal and less primal, creating kind of two people. It won't be like he switches back and forth, but that'll be why he talks to himself in his head. Also, it makes sense for him to develop a disorder like that since he spends a lot of time in other people's brains. Part of him wants to be with Aruna and be a normal person to interact with her, and part of him is used to being a primal Wolfen. That part was shunned, and he's not good at being the other part, making it hard for him to define a personality. Without the moon to turn to like a normal person in the Rakatsuki religion, he'd kinda go crazy-ish. That could also be part of it, inspired by the whole "Full moon" on wolves thing: if the spirit of the moon is now evil/being impersonated/all fucked up (I can't remember if we decided), then that would be hard on him, which is also why he can't sleep.
Anyway, point being, I want to give him a form of DID that's kind of just him being a very defined two-sided coin, making it hard for him to make decisions and stuff because he argues with himself. It won't really change how I play him or anything, just help me make more sense out of his character, plus give me some RPing filler and some reasons for him to be unstable when it comes to Aruna, as he already is. if she has any background in medical things (you mentioned once she might know how to use healing magic, so I don't know if you decided or no) then she could diagnose him with that sometime in the future, and if not someone else will or he'll just figure it out since he already uses his mind so much. If he figures it out, he'll figure it out soon.
This is your game too so I wanted to run it by you and make sure it's okay. Minor DID/specific bipolar disorder okay? Does it make sense or is it too much?
