[Out of everyone that's been with Tony for years and years (and that list is very small), Happy might be the most attuned to what the end of a long boy's night out looks like. Or what cleanup may or may not be involved. At least right now he has Steve as his wingman to help with that. Even if Thor's a bit more than he usually bargains for.

Tony, meanwhile, is feeling the world still crawl by him in a bit of a disorienting manner because everything is moving and now he's moving and it doesn't feel great. So he's glad to have Steve to hold onto, one arm around his shoulders as he's being carried, face tucked into the side of Steve's neck.

There's still more drunken murmuring, because Tony never shuts up on a good day, but especially when there's absolutely no filter.]

Gonna carry me like this- over the threshold- when we get married? Then maybe I'll put on the suit. And I'll carry you.

[The sound of the elevator doors opening and closing and then opening again as they reach the Penthouse completely goes by his notice. All that matters is that Steve's got him. And, because he brought it to his own attention, he presses a smile into the side of Steve's neck next and can't seem to delightedly and drunkenly help say-]

We're getting married.

[Which of course, yes, he's still very excited about.]
