The thing said to Lucas on the Owls stream that seemed to piss him off as much as the 'bitch' comment was when I told him he really doesn't mean anything to me; that I don't think about him nearly as often as he thinks I do, that nobody is really worth the time, effort, and energy of hating and I just find him pathetically funny, and that it takes very minimal effort on my art to copy paste his shit into a video and upload it directly from the editing app.
Could tell that he was so sure I was a centerpiece in his life and, like any narcissist, to find out he wasn't, gave a flash of a look like I'd just stabbed him in the throat. He covered it up well, they always do, but that one pissed him off.
