Kaidan strikes me as one of those people that you would not expect to listen to metal but he started listening to it as a therapy tool like a coping mechanism outlet for anger and it mellows him out so much that he uses it like white noise to fall asleep to and you can't change my mind on this.

being frankenstein-ed back to life against their will had to fuck Shepard up a little bit but the game just glosses over it and jokes about it except for like that one part in the cerberus headquarters at the end of me3

I honestly can't separate Dmitri from Kaidan to even try to think about what he might be like with another character. Any alternate universe I've put him in I've always pictured Kaidan being there with him. Dmitri is in my brain putting his foot down about loving Kaidan and only Kaidan and he won't even let me consider other options.
