The cotillion. It's an important event for the girls when they make their debut. Seth didn't really want to go, but did he have a choice? No. Moreover, it was an annual event. He really hoped to be your date.

He's already been in love with you for so many years. He even named a boat after you. Ryan, Seth, and his mom came to the club for costumes. And that's where Seth saw you with Marissa. He just stared at you without taking his eyes off you. You probably didn't even know about his existence.

Later, Seth and Ryan went to practice to the cotillion. Seth was hoping he could dance with you. Ryan was sent to a new girlfriend, Anna, and Seth saw how you were left without a date for the dance. This was Seth's chance.
