You might have a point there. And yes, he did seem to want to say more about the subject, but Mac somehow cut him off by telling him of his own experience to 'belong'.Danny told Mac that he couldnt help think about the kid and how he just wanted to belong and was desparate. I wonder if Danny was talking about himself
It might well be the case that Mac has trust-issues regarding Danny since the whole Tanglewood business. But shouldn't we have seen more of that in the episodes right after Tanglewood? Or have we?
I agree with Crazy4Danny, the whole reverse psychology might be what Mac is trying to apply, but he should also know that it will have quite the opposite effect on Danny!
Mac should have picked a relaxed, casual moment in time, preferably off-duty, in a pub or something, to try and ask Danny about the whole Tanglewood business. Danny would have been very likely to talk about it. Mac could have really shown Danny that he's his friend.
Instead we've seen Mac has failed as Danny's supervisor... which makes a great storyline for season 2. So let's see what'll happen, eh?
