[Scott had someone to fetch before he makes it to Lydia's party. Spur of the moment decision, here, as he showed up at Billy's door, told him he needed to get semi-dressed up because they were going to a friend's party and 'no' wasn't a proper answer. He's sure Allison willy probably be here too, but distracting Billy from his worries came first. Scott will spend the night not thinking about his missing friend while making sure Billy spends the night not worrying about his missing boyfriend.

Into the ball room they go after much convincing from Scott.]

Lydia's one of my friends from back home. She'll be the amazing redhead in probably the most expensive-looking dress in the room. If we were back home, it'd be her birthday soon. And she's known for throwing the best parties in Beacon Hills though, so yeah.
