I don't think Myka was in any doubt about what they needed to talk about, he'd already expressed that in the previous episode when he said she didn't talk to him about leaving. I think it was more that she hadn't realised it was sat on top of these previous losses. Although he'd just been dumped by Kelly prior to her going which was a bit of a clue. (Sometimes the convenience of the plot makes our charaters a little clueless which is always annoying when they're presented as intelligent people.) I doubt she was instigating therapy when she talked to boy Pete, I think she unwittingly touched a raw nerve and tried to comfort him by talking through what upset him. Anyway, it was a very nice scene with an insight into Pete's past. I think boy Pete was sweet. I have to say that sometimes Pete is very attractive then he opens his mouth and let's you see his breakfast ...then not so much.

He's still funny though.
