Lydia & Sam
Sam still vaguely remembered the first Lydia who had been in town. They'd been friends. He didn't really know this one, but that didn't stop him from saying hello, when she turned his way and made eye contact.
"This is a great party," he said with a nod. He'd seen her adjusting decorations, and knew she had arranged a few other parties in town. It wasn't a hard stretch to assume she had something to do with planning this one.
