Also -- good point about how the male characters seem to be getting the roughest deal on this show. I don't think that (if Hotch were indeed sexually assaulted) that would be redundant to Morgan's story because the context is entirely different. Morgan was abused when he was a kid by a figure of authority, and maybe that made him want to go into law enforcement to catch bad guys (?). But Hotch suffered the abuse on the job, as an adult. I think the dynamics are entirely different and while there are similarities (such as hiding what happened) it won't be too much alike to feel like a redux.

I do believe it would easier for the writers to do a decent job at dealing with PTSD for non-physical/psychological rape than it would be for actual sexual assault, especially given the constraints of procedurals and their poor track record of continuity.

After some mulling I do have a couple of other theories about what happened -- maybe a sign that I should get back into writing CM fic, which has always been a great way of filling in the canon blanks :)
