It is exactly the right thing to say. Bruce relaxes under Tony's hands with those words and lets out a breath of relief. It gives him enough courage to lean in and actually press his lips to Tony's collarbone, remembering how it felt to touch Betty and feel taut, warm skin under his lips of someone he cared about. Tony might have been trying not to think of Pepper while they lay here like this, but Bruce is the opposite. It isn't tainting a memory, it isn't guilt; it's only adding to something he holds close in his heart.

Bruce still doesn't fully understand why Tony chose to do what he did for Pepper. No, not that he doesn't understand that Tony loves her enough to do it... but he doesn't understand how Pepper can't see that Iron Man is as much a part of Tony as is the need to breathe. There is something lesser about him, in how he carries himself.

He thinks Tony misses it.
