Barry finds strength from Lena. He stands up to the brothers and mattress man. He brings the piano to lena's door and she forgives him. We then see her asking Barry (who is fluently playing the piano) if he is ready to go on their trip. The two outsiders had found love through each other.

Lena: Oh... I'm sorry... was that like a secret pudding?
Trivia: In the movie Barry buys lots of Healthy Choice pudding to get the frequent flier miles. In real life Healthy Choice had this actual promotion and there was a news story about a man who bought a lot of the pudding and got enough free miles to fly his family on quite a few trips to other countries.
