i can see that ha! no, i don't believe he was, at least not in my time. but i am intrigued! rafe is missed, but no. i usually prefer to focus on one character at a time because i'm just horrible with time management that way.
hope you don't mind a little c/p: peter is an introvert through and through, and legend has it that he once was an indefatigable optimist before life browbeat him into the husk of a curmudgeon that he is. he's pretty gruff on the surface, copes with the things he sees on the job with the kind of black humour that's totally fucked up in any other context, has zero tolerance for liars, has pretty thick skin and doesn't mind treating people shabbily to get at the truth. but he actually does care a lot more than he lets on with a very strong sense of justice. prone to lacking compassion in words but compensates in action. so a bit less morose but unexpectedly darker character than rafe.
