[If he knows it's going to get him worked up, why is he doing it? That's the question Bruce would ask if he weren't oblivious to the machinations going on under his nose.

He notices a strange quirk of a reaction for half a second, but before he can identify it it's gone, and Tony's launching into another explanatory ramble. Bruce raises an eyebrow at him, but listens, storing the information away neatly in his mind.] I've met Loki, [he contributes, tone even.] He was here for a while. We didn't get along either.

[It has the ring of a vast understatement to it.]

I'll have to get the full story sometime, but right now we need to, go over everything. With the timelines and the... doubles. You're still hung up about it, aren't you? [That's Bruce's version of being comforting and saying that he's open to working it out if he wants. But he can tell from that evasion and awkwardness around talking about it that Tony's seemingly innocent question earlier about whether he knows he's not the same guy is at all over.]
