Plus, this is the last time he will see her. Likely ever. Its not like he can blow her off this time to "teach her a lesson" then go meet her in a couple days and try again. She is leaving. I bet marten wusses out and goes down there, only to see her making out with big guy. Her justification? "You didnt want to be here, and I wanted to blow off some stress before I go." More drama ensues. Mostly marten scowling to himself and his friends as she will be gone the next day.
