Atreus came after Fight Club, in lady-form, red hair up in warrior braids, gold dress that was a surprise for Lance. They were with team Voltron and would've brought Angrboda along too if she wanted to come! Atreus is all about the food and drinks and is not an especially good dancer but they try~ Atreus would've hung out with friends and chatted and been in a pretty good/buzzed mood most of the evening. Winked at Noct for beating them in FC ;)
Ignis came after fight club, in a sparkly suit, with eyeliner + black/gold flower crown. He loves fancy things and swanky affairs and dressing up so he's super into this. He always makes way for the food tables just to sample things and quietly judge (sorrynotsorry) but he also dragged each of his boyfriends out for a fancy dance or two~
Laudna lives her life like everyday is a goth prom so not much changed there. She loves dancing! and vibing! And having a good time! She's there with Imogen and Dorian for sure and probably some other Bells Hells members! Just floating around as you do~
The rest of mine depended on their SOs/friends! Evie wasn't there for sure but Jayce, Caleb, and/or Syd could've been dragged along with minimal effort if their people wanted to go!
