Steve's aware this would be a great opportunity for Clint to shake him, but he's also pretty sure Clint won't. He's not sure why, except somehow ending up on the floor together and a lot of that talk felt more... solid and real than anything has in a while.

He doesn't rush back. He picks up his backpack with his stuff, and does what he said he was going to. He takes the long way back, getting some idea of a place that will work for privacy for an intense sparring session without getting authorities or spectators involved, and makes it back within that half hour.

He hesitates outside the door for about half second, then raps on it with the backs of his knuckles. It's pretty quiet, but if Clint's expecting him it should be audible enough.
