Tony & Darcy
"I'd be a hypocrite if I did. You're old enough to make your own decisions. You did turn out awesome, after all." He winced a little. "One thing. Can you try to maybe not bang aliens anymore? Asking too much, because hey, if you like it freaky...I can't really say no. I know past you and other Loki were a thing, and he's not that bad anymore...."
Tony still wasn't aware that Loki was a lady at this party either.
"...ok nope," he stopped before he went too much further, "I'm probably projecting my mass phobia about space onto this. Gonna back that up. We'll talk later, not on New Years. You do you tonight, and anyone else you want to do. Wanna hug it out? Maybe revisit this whenever you want to drop in and talk? Literally any time. Don't care when. Or how often."
He opened up his arms, raising his eyebrows a little.
