I agree that it is pretty clear this wasn't the first affair, but as much as I hate to give Tori any credit I was glad she admitted why she hadn't asked him-- because she would have felt like she needed to leave him and wasn't ready for that answer. Not standing up for her, but I was surprised she admitted she hadn't asked and why. I think there were several internet articles that referred to previous affairs (not necessarily from great sources), but I think that it alluded to multiple affairs. Plus since he admitted he cheated because he could, I doubt this was his first one.
I was also glad that Brooke at least asked many of the questions that people have brought up. We know Tori and Dean's answers will never be satisfying, but at least Brooke did ask many of them. I like Brooke, though, and I think she does a decent job of not alienating those she interviews and does try to ask the difficult questions. I was very annoyed that they acted all private about their love life all of the sudden, but honestly I was more annoyed that Tori has been "intimate" with him already...such a short time has passed and it was clear she still felt very uncomfortable with everything. I personally would respect her more if she held out longer, but this is the Tori that "did things they had never done before" just to try to make him happy.
I was glad that Wolf explained his role with Liam...since we had never seen him on any other show I didn't realize he had actually been a family friend for a decent amount of time, but it was clear that he does spend time with Liam, and they are close, so at least that made more sense to me.
I was relieved that all we saw from Dean was a tattoo and a song...I was ready to cringe at him giving her that Neil Lane ring we have heard about.
They have a lot of work to do...they can pretend all is well, but they are clearly all f***ed up individually and as a couple. Time will tell, I guess.
