Carter's last day at County General is marked by the "surprise" party being thrown for him. Ray takes charge when a balcony collapses at a party that he's attending. With all of the attendings at Carter's party, he talks Abby into taking 4 trauma pat... (more)ients while the hospital is closed to trauma. Pratt briefly visits his dad. Alex doesn't know his dad is in jail and is upset when Sam won't let him visit him, so he steals her credit cards and hitches a ride out of town.
