LOKI
Once Loki was finished in the kitchen with Elsa he changed into something nicer. He had promised Natasha in New York that the next time there was a party he'd wear a tuxedo, but his mother was in town. So he went all out fancy Asgardian style. Very traditional robe-like attire. Ceremonial in appearance. Black, green, and gold of course. He was his mother's date for the evening and definitely made a point to introduce her to anyone he considered a friend. He didn't try to sit by anyone in particular, aside from Frigga, and welcomed anyone (within reason — sorry, Matt, not you) to join them. He did not drink any alcohol during dinner because he promised Elsa he wouldn't indulge in spirits until after the talent show. (Even though he was fairly certain he could still hit the mark with his knives while he was inebriated. But, you know, probably not a good idea to kill another queen...) He enjoyed the salad and the risotto. He stayed away from anything that was dripping in cheese, deep fried, or looked like it was sold on a back alley in Brooklyn.
