Bryon and Mark go to the bar/pool hall owned by Charlie a friend of Bryon's and try to hustle some people at pool but find no one to hustle. They meet up with M&M and go to the bowling alley it's a long way so Mark offers to hot wire a car, but Bryon says no because Mark is still on probation for the last car he stole. M&M decided to leave the bowling alley before the others. M&M noticed that 3 guys are following him and it was Curly Shepherd and his friends. They begin to try to start a fight then Mark and Bryon jump in and beat up the three boys. Mark takes money from one of the boys to pay their bill at Charlie's. The next day they hitched a ride to the hospital were Bryon's mother was recuperating from major surgery.
While there his mom asked them to go see Mike, a kid across the hall who had been beaten up and had no visitors. Mark went but Bryon went to the snack shop where he was waited on by Cathy who was M&M's sister. Cathy reconized Bryon but Bryon didn't recognize her until after they had talked for awhile.
Bryon left the shop and went upstairs to Mikes room, Mike told him that Mark had left but had said for him to wait for him. While they waited Mike told Bryon why he had gotten beaten up. He had rescued a black girl and had taken her home, she was crying when they arrived and her friends thought he had hurt her, they drug him out of the car and beat him after she said to. Mike told Bryon he was not mad at her or her friends, he understood why. Mark arrived and he and Bryon left, Mark told Bryon he though Mike was stupid. Bryon tried to get a job with Charlie at the bar but Charlie said that things were to tight to hire anyone, but Charlie did let him borrow his car to take Cathy to the dance. Mark went along with themwhen they got there he sat with all the other boys without dates. He sat down next to a young man named Ponyboy Curtis. Angela, Bryon's old girlfriend tried to get Ponyboy to dance with her but he would not. This made her mad so she told a friend to beat up Ponyboy. Mark tried to stop the other boy, but got beaten up and had to be taken to the hospital. Bryon visits Mark and he tells him why his parents killed each other over the fact that Mark's father was not his natural father. Bryon visits his mother again and sees Cathy while he is at the hospital.
