I wrote about this already in the Survivor pool thread.
I think Sue made a big deal out of nothing. I think she knew she wasn't going to win and wanted out. I don't know what her relationship is like with her husband, but I think when he watched what happened with Richard, he knew it wasn't her fault. It's not as if she was flirting with him and said, "Oh, Richard, please slime your little (well, maybe it's not little, I've only seen it blurred) penis on me."
As for Boston Rob, didn't like him before and really hate him now.
