Melissa's Part 1 Jacob: He came with Serefin in something slightly old-fashioned but still COOL until you get to the shoes which were the furry green golf shoes he wore in his promposal. He danced some with Serefin and any of his friends (even you diego come on you knob). He had a fair number of drinks, including a shot that made him lose his voice and only be able to sing. He's actually got a great voice for this but he's an idiot, so please assume that 15 minutes was annoying anyway. Eventually he snuck off with Serefin to snoop as per tradition.
Ronan: He came with Adam and his friends in a black suit but with a pale blue blazer so he'd look good next to his husband. He ate a lot and danced more than expected (including a showdown of bad dance moves with Blue). He avoided the shots but got himself a colorful non-alcoholic concoction to nurse. He's not really a PROM guy but he's loosened up a lot since HS and really loves his nerdy little family so he made an effort to not be a party pooper.
Lila: She came with Diego and her adorable baby. She wore this slinky number which isn't really meant for dancing but she freaking did it anyway. She loves a party and she's not shy so if you wanted to dance, she was in.
Noct: He was there with his fiances. He stuck to his black suit vibes, but wore a purple tie to go with Ignis and Gladio. He's my biggest wallflower so the guys had to drag him out to the dance floor but once he was there, he was soft and enjoyed himself. He drank a bit to loosen up and ended up an otter for his trouble. It's fine. He can take a little otter power nap.
Rocket: Baby Groot heard there was dancing so Rocket snuck them in and stole a bunch of food with his little grabby raccoon hands while Groot danced with anyone willing. Also he took a shot and end up looking like a drowned rat. Eventually he spotted one of the otter people and had to grab Groot and run. Did you notice he was teary-eyed eyed as he fled? NO YOU FREAKING DIDN'T. BUZZ OFF.
