Typically, Clint wouldn't let himself get sloppy in new places, with new people, in unfamiliar terrain. Typically, Clint wouldn't drink much on the whole, far too aware of the slippery slope it led to and the numerous more fuck ups that could involve. He'd had a talk with Stark about it once, in the old days when they hadn't died a couple times fighting for the world or lost best friends and lovers to the madness that this lifestyle brought. It was easy to use a crutch for coping, easy to excuse the need, look for an out. But they both knew bad coping habits and had a strong desire to not be like their fathers. After Carol's issues, Clint was sure Tony was trying to look out for the punk ass kid he'd brought into the shit show that was the Avengers.
But all that became moot when it was Natasha.
Because Natasha had his back, she always had. Natasha wasn't about to let him fall into a bottle, she never would. Natasha probably wouldn't let him sleep in his own vomit, they had no basis for that yet, but Clint's sure it wouldn't be an issue.
Somewhere through the night, he lost the jacket he was wearing, and the tie he'd found was somehow caught on something and missing the bottom end, his pants had a rip in the pocket and Clint wasn't sure if these were even his shoes. Sometimes, these things just happened. Letting Natasha guide him wherever she wanted him to go let him at least shut down his very tipsy brain, allowed him to keep his mouth shut too -he was sure he'd commented on her dress more times than he needed to.
Leaning on the island counter, propping his head on his hand and watching those dancer motions as Natasha walked was soothingly normal, even if he and Nat hadn't really been in that zone for a while. They probably hadn't played house since before Carol and Tony's little spat. "You know, that's a very Natasha thing to say." At least he wasn't slurring too much.
The multiverse seemed to be rather new to her, which put them on an odd playing field, Clint knowing more about something than Natasha. "We've gotten a little better at recognising the hoaxes. Some people just can't be faked." Competent Clint worried him after all.
