[ Jace nods cheerfully while he drinks. Yes, he knows you just cleaned that. Yes, he's drinking from it anyway. Yes, he's definitely at least a little tipsy by now and has likely left empty shot glasses scattered around the place without a care. This is exactly what does help, though, since if he didn't make a mess, Alec wouldn't get any joy out of cleaning one up. ]

Better me than someone else. Here, you should have one.

[ And he fills a second, before offering it to Alec with an expectant look. ]

Go on. You're officially off duty, it's allowed.

[ Not that anyone has anything like official duty here, anyway. Jace leans back again. ]

You know I didn't know Magnus could do that with his powers. His runes look pretty solid, too.
