Emily will probably be hanging out with Kat and texting Ollie in between being social.
Claire will be rushing around making sure the bonfire goes according the plan and Andrei doesn't RUIN it! She probably will need to drink a bit to calm her nerves.
Adina will probably want to spend time with Dana as much as she can. Besides that she will be going around to the different houses and participate in events in her sexy Elsa costume.
Jasper doesn't have a costume so is basically going in his normal clothes. He's all about enjoying the different houses events as last year he thought it was stupid and stayed in his room. He's very interested to check out the girls in the sexy Sailor Scout outfits.
Dallas is on guard. He's super focused on protecting the kids and his wife. So he will probably be migrating between his wife and patrolling the wood with a sword...and a fireball in the other hand. Nothing is going to hurt his kids or his wife on his watch.
