There's only one thing I can think of that Dylan might say that would upset him enough to actually hurt him, and that is that Mike is a better father than he could ever be and he's glad they're going to be a family. I just don't believe he'd say it, but anything is possible.
I personally don't see the controlling behavior in him, though, so maybe I am just totally missing things. What I saw on DP was DP asking him a question, MR starting to answer and one of the other people interrupting him to yell and/or insult him, accuse him of lying, or whatever. He usually shut up until the rant was over, tried to defend himself, and DP would more or less tell him to shut up - which he did. His exes were both strong, intelligent women, and I find it hard to think of them as being easily controlled/manipulated by someone who seems so inept at it. I'm not saying either woman has lied about what happened, but I wonder if the reasons for his actions were what everybody thinks they are. (No offense intended to either ex. I see nothing wrong with being strong, intelligent and not easily controlled!) MOO
