After that, he fell down some stairs and got sent to St. Joseph's Medical Center, where he was treated. Mandy had paid for his medical treatment.
Later on, he started treatment for his drug addiction and alcohol addiction, even going to Alcohol Anonymous. He also was arrested for crimes and put on probation, so he was not able to leave the state. Georgie visits him asking to give money back, for the medical treatment in NYC. He welcomes him in and talks to him, and says part of healing is to resolve issues. As a result, he writes a check and gives it to Georgie.
