I know what you mean. I think he's spent so long shutting off his emotions that when they surface like this, they overpower him; so he shuts them down even more. Not only that, but this reunion with his brother is bringing back some really deep wounds... I think the only way he'll get over it is by confronting him himself.

I already told him I'd be there for him if he wanted to discuss anything, but it's so hard for him to take initiative that... well, I don't know if it'll do much good. I'm doing what I can for him; I hope he realizes that there are others who worry about him.
