I like Chad too. He's funny, honest, and good looking at least. But his short fuse and the lack of a filter around Jojo are not doing him any favors. It's one thing to try and come off as the alpha male when in the house around the guys, but no girl is going to appreciate that.
Evan being a tattle to the host is annoying, and then Derek feeling like he needed to change rooms because it wasn't safe to sleep next to Chad is asinine too. I tend to agree with Chad when he says he's not the one starting the drama, it's the other guys. He seems pretty quiet, but when provoked, that's when he takes off. The other guys are too concerned about him working out and eating, which are pretty harmless activities!
