Peter & Loki (multiples welcome)
Loki wasn't sure what graduations were all about, other than it might be some right of passage when a Midgardian reached their age of majority. He was used to feasts with food and music, and he enjoyed those very much. His wife was still finding her footing as far as socializing went. He was fairly certain that she would be dubbed a 'workaholic'...which was a word that he heard Stark say a few times, while breezing past underlings pestering him with incessant questions.
At least this event coincided with his stay in the Tower, so he was able to attend.
He held a drink in his hand, a soda with some oddly peppy name. It was a sickly sweet dark brown concoction, with bubbles that tickled his nose. While the sweet was cloying, he loved champagne. Alfheim had entire rivers of the stuff. There were plenty of games to look at, including video games that he was fascinated by. At least that was the case until he spied Peter, and he closed the distance with a impish grin.
"Hi," he said as he approached. "I wish to extend my congratulations on your graduation. Did you slay something in particular as a means to prove your worth? Or did you face off against an opponent in armed combat before your peers?"
