Billy can be an asshole, obviously, we're here for fun (and he can be when he's like that) but is there a thought process you have for scenes where acts out? Do you have to play those over in your mind first?
I mull over the different 'routes' he could take, and usually go for the more emotionally charged one - especially if it's something that's angering or challenging him, he's going to rise to the bait see interaction with kavinsky earlier this year >>;
Sometimes it's really easy to come to the decision of what he's going to do, sometimes I really gotta think on it, and see how far he's come in his growth and what not first before I can reply
