"Yeah, it's one of those episodes. Phoenix Academy and Eclipse Academy are, for the first time ever, holding a joint prom. As far as you're concerned, supervillains, their nefarious schemes, and the end of the world can wait - prom is the most important thing that's ever happened to you, ever. And nothing is going to ruin your perfect night. Absolutely nothing... right?"

Since it's a joint prom she's attending with her brother who is a student at Phoenix Academy, but she doesn't have a date date. Her brother is going with his boyfriend (https://www.westmarches.games/communities/eclipse-academy/characters/cmrpvqpqd001904jo1pjlpup5) but he is also chaperoning Medea to make sure she's socializing and not just bailing and going back to her room.
