Some male students at a basketball game are shirtless and have the letters spelling out the team's nickname written on their chests. Some students briefly drive down the wrong side of the street next to Chase and Nicole.

Students make out at a party.

He tells her that nobody's going to know about it, but she still doesn't want to fool around with him. She later tells him that she's upset with him about his distance. Nicole and Chase's plan to act like they're dating each other to make those they're interested in jealous.
