Gavin and/or Garrett
The Ogletree twins arrive in identical black suits with identical gold accessories and identical-but-inverted sun and moon masks...which makes them relatively simple to identify regardless of the charm as long as they're together. This doesn't bother Gavin, though, who's acting the way he always acts during parties: confident, charming, outgoing, and upbeat. He'll talk to anyone, try anything (that won't instantly get him into trouble), and dance with everyone. He wants to be included and he wants his brother to be included and he doesn't want to miss out. While he intends to stay with Garrett for most of the night, he would like to get some one-on-one dancing in with a few cute mystery girls or mystery boys and scans the crowd from time to time.
