It's that anger he saw in Tony's expression earlier that stops Steve from pushing when he normally would have insisted they go to Medical. Broken ribs can take a month or two to heal, but Steve is willing to bet that Medical could take care of something like this in 20 minutes. He doesn't know that for sure, but given the other Medical marvels he's seen here, he wouldn't be surprised.

But still, whatever just happened, he can tell that Tony's going through something more than just the physical pain, so yeah, okay. He won't insist today.

"Alright." He slips the gun out of Tony's hand then, and puts it back into his holster. "Come on. I've got ice back in my apartment."

He also knows that Tony's going to ache in the morning once all the adrenaline truly wears off. If Steve can get Tony to go back to his place, then at least Tony can sleep in a bed all by himself and not have anyone disturbing him. And in the morning, Steve will cook him something piping hot to help warm him up.

And yeah, technically speaking, they were also supposed to have their first real date tonight. But given everything, Steve's pushed that to the back of his head. Now that the fighting's over, and he sees the other Specials in the room taking care of each other, his focus is completely on making sure that Tony's gets everything he needs to heal.
