He gets it. This whole reaction, this jump to anger because it's easier, he gets it. He's been there, he's been that guy, he is that guy more often than he likes to admit. He isn't intimidated by it, he doesn't even seem particularly affronted or ruffled. He's just... steady, that same older brother steadiness he developed for Sam, the same steadiness he employs for Steve now, or for Clarisse, or for when Cas is taking his turn having a crisis, or when John got pissed.

Weathering the brunt of someone else's emotional reaction over something unrelated to himself is old hat. He doesn't mind it.

"Yeah," he returns, a mild but not insincere agreement. "It's over."

That matters. It's not all that matters, but sure.

He doesn't know Michael well enough to push any further than this, they don't have the necessary rapport for him to try any harder now to knock down walls looking for something more honest. He'll leave it be.

But they both know Dean knows there's more here, and Michael's anger doesn't do a damn thing to discourage the notion.
