Teddy TEDDY was there with Billy! He wore this suit and paired it with a tie designed like this but matching whatever color Billy was wearing! All done in the hopes that he was enough on theme to fit in with a blue suit and holographic fish scale tie. I want to say that he was his normal self, so green! Overall, looking snazzy.
He stuck at Billy's side and would have danced the night away, tried food from literally ever table because it's FREE so of course he did. Mostly, though, he just really relished in having the ~prom~ experience with Billy like this and was just utterly charmed the whole time by his boyfriendhusband. He would have also been chatty with folks he's met and is friendly with, too!
Teddy probably just had, like, one drink before switching to soda, so he was a sober dude to make sure his people got home, as needed.
