in response to your saying he looks like he doen't want to be there: I think he doesn't know where he wants to be, right now. He hasn't figured it out. He's painted himself into a corner and dug himself into a hole there.
It's tragic, really, in terms of his life's effects on other people, to watch Brady piss away so much of what really matters at the expense of what really doesn't.
I hope, for what he can salvage of fatherhood for the benefit of his children,(already damaged) that he does figure it out.
The downfall of the tragic hero draweth nigh.
Poor Tommy Dimplechin.
