Callahan is a character who is still discovering himself, because 16 chapters in I'm still kinda figuring him out too lol. Main characters are way harder to figure out for me than the side ones. Of the trio he's my least favorite to write, not in the "I hate him" way but in the "Hm... would he say this?" He's definitely the reluctant hero arch type, but he's not particularly good at anything. He's pretty lucky with his aim, though that's not a story arc thing, I just found it funny that he managed to get a couple head shots with his goofy weapon. I think the trio works pretty well together, and Cal and his brother I think are fun together, but I did rewrite chapter 2 because I couldn't for the life of me figure out how to get Cal from one place to another without somebody pushing his buttons. I have an idea of where I want him to be in the future, and I think he's pretty okay as he is now, at least to my standards anyway which are... uh. I dunno probably not very good. But yeah, I still love him, and his brother and his little fairy.
I am not good at advertising or selling my self/characters. but I do like talking about them when I get the chance every so often.
