Noah was putting Jess's suitcases inside the trunk of her SUV. They are using her car because Noah's sports car doesn't have the space for her luggage.
While Noah was putting her suitcase in the trunk, Jess and Luke were saying goodbye to each other like they weren't going to see each other for years instead of a few weeks.
Luke was being overly dramatic with their goodbye.
"Stop acting like you're going to miss me," Jess rolled her eyes. "You have my black card, my car, and my apartment."
"Still, it's not bad to act like I'll miss seeing your pretty face, but I'm sure..." he nodded his head in Noah's direction, "he's going to miss you badly."
They're a bit far from where Noah was and Luke lowered his voice when he said it, hence, Noah had no idea they were talking about him.
"Don't be silly," she tried to not show how much she likes the idea of Noah missing her badly. He doesn't want to give Luke more reason to tease her.
