I mean I know you're pissed off b/c you thought you were in the clear but you treat Jessie and Ronnie like they are the scum of the Earth.
Jessie did what he thought was best for him and he needs Ronnie to keep the numbers on his side. If Casey doesn't understand this, then he is the moron he ended up being.
Instead of going out with some class, some dignity, he not only sounds like a fool in his final speech but he continued on Jessie after he was voted out.
What's talking down to Jessie going to accomplish? He's one of those people who needs to get the last word in or else he feels unimportant.
Good riddance. His true colors showed and nothing pleasant about it.
