Well I think a lot of the conflicting opinions come from the fact that Catherine really will react any way she likes. Marg herself said she thinks that Catherine will be supportive and that she already kind of has the feeling that something is going on, but it's really more up to the writers. And, truthfully, who Catherine approaches about it. It's entirely possible that it'll be Sara, in which case who knows how that conversationw ill go? I do like the Hank flashback. lol.
