How did the date with Cathy end?

Bryon takes Mark to the hospital, where he gets stitches. Cathy and Ponyboy take Charlie’s car to the hospital, with Ponyboy hotwiring the car after learning from Mark. Bryon realizes that Ponyboy is actually really nice and there is no need to hate him. He takes Cathy home, debates whether or not to kiss her, and doesn’t. Back home, Bryon and Mark talk in the moonlight, and Mark says that Bryon is his only real family left.
