Exactly what happened to Trip Fontaine as an adult
After his narration of his relationship with Lux we see a woman, probably a nurse, to come into the room and tell him his group meeting is about to start.
He's not happy about his decision to leave Lux after having sex in the field and apparently something went wrong with his life, he doesn't seem the irresistible and arrogant youngman he was when we first meet him.
Any ideas?
