He is bugging her

Ethan is trying to get all his teasing in before he leaves for 2 years for his mission.  He was doing his best to bother Courtney as much as he could.  It was hilarious to watch.  He will lay on her, sit in the seat she was sitting on, lean on her, read over her shoulder (which she does to him just to bug him), etc.  She doesn't know what to do with him.
