Loki would not have texted Alastor to invite him, honestly, even if he had contact information for him. In general, he feels the more the merrier, but he's just wary enough that he wouldn't want to expose his alternate to this individual. He's sure that he is very, very dangerous to a human. Whether he's powerful enough to be a danger to a god, he can't tell yet.

So sue him, he's a little protective of his poor, doomed twin. Harley, too, although really they can both handle themselves.

But there's no harm in having a milkshake. He'll just be keeping a close eye on Alastor for the duration. In fact, when he sees him approach, he stands and beams like he was expecting him. "Hello, yourself," he says. "It's an informal celebration; no assigned seats. By all means."

He resettles in his previous place. His milkshake cup is long since empty, but he's got coffee he's nursing, now, and a pile of broken cherry stems, one of which is in a very bent-up approximation of a knot.
