Anthony Edward Stark

The show is everything he'd been after when he'd taken them well beyond a bit of making out. He watches Tony with an intense need to commit every second to memory. It isn't often anyone gets to shut Tony up.

When Tony collapses, he takes his hand away and wraps both arms around him to hold him while he catches his breath.

It's interesting to note that without Tony's urgency to compound his own, he can relax a little, start to think a little more clearly. What had been building between them had been greater than the sum of its parts, some synergy that has released Bruce to breathe, given him room to wonder whether Tony would disappear if Bruce got up to finish himself off in the shower.
