MEGHAN! Gladio: came with his fiancees. He wore black and purple as well (though the shirt was solid black. He is here for a good time, will do all the dancing and eating/drinking. Will sing at one point, sappy love songs to Ignis/Noct/Prom, enjoy!
Lance: was there with Atreus. He has this fun jacket with dark blue pants. Is heavy on the PDA he's not sorry. He'll have a few drinks - one that will turn his hair into seaweed - but isn't getting too crazy because this is technically a work event for him lol. Will man the info booth corner for a shift or two and is very good at "encouraging" people to hit up the donation table. Will dance with all his people and just generally having a good time.
Talcott: came with Matthew. It's not a a date! See his suit doesn't even have a tie so it's not a date. Will be dancing when someone talks him into it, eating the food. IDK who else from that group came but will be hanging around whoever does! Isn't a huge drinker but enjoys a fancy cocktail or two and ends up with bubbles coming out of his mouth. The important thing is he is not here on a date.
IDK, I may have forgotten someone and might come back.
