The thing is, they didn't really show much - but they implied it all in the squeakiest way possible. I love that device CM uses quite often, as much as I hate the squick.

Derek has been the sensitive one before - and I think that worked for me. But I think reid should have also been there as he might have found a way to communicate better/faster with the poor guy.

I doubt JJ is having and affair though. Something is going on, but not that.
