Porthos - Is a priest and hammed it up. Kneel if you'd like to be ~blessed~.
Peter Kavinsky - came as a romance cover cowboy. He's not much of a drinker but he had a cupcake so congrats Covey, his playacting got extra corny and real. ALSO he did the thriller dance and treated it like a country line dance.
Hawke - dressed as a mermaid because he's fucking ridiculous. I'm sorry. He's is prettier than this at least. He'd drag Fenris along if Kate's down, otherwise he'd hang out with Isabela . He had the milkshake shots so feel free tell him to do stupid things that he'd probably have done after a few normal drinks anyway. He has next to zero shame.
Ezio Auditore - channeled his Breck self who had some serious fireman envy. He made goofy heart eyes at Leo a lot and made sure Leo didn't fall down in his crazy shoes. ALSO he had a ghost strawberry. Luckily, he's vain as hell and is totally fine with giving even a silhouette show.
Penny - did not wear a costume, but he DID do this face paint on himself and it goes all the way down his as always exposed chest. He had the jello shots, but LOL following ghost advice yeah right. He'll just be annoyed and yelling at them to fuck off. HE will do the thriller dance though. Happily even.
(I have candy corn bark to make for a party tomorrow but I'm going to come back to this in a bit and reply to other people!)
