Johnny killed Bob for drowning Ponyboy and they ran to Dally to get some money and gun.
Come on Johnny let's run away!
Oh no! Socs!!!
What are they doing here?
We hate you hoods!!!
Ponyboy tells Johnny they're going to run away because Darry slapped him. However, they decided to walk a while to cool off before doing something crazy.
While Johnny and Ponyboy are walking, a blue Mustang stops. Right after, a group of Socs comes out.
I had to do it Pony!
Two of the Socs are Bob and Randy, who were Cherry and Marcia's, boyfriends. They were angry with them for picking up their girlfriends. Then, they start fighting.
Thank you Dally!!!
There you go guys, $50 and a gun.
Go hide in the abandoned church.
They keep fighting. Suddenly, Bob tries to drown Ponyboy in a water fountain. Ponyboy can't breathe and passes out.
When Ponyboy wakes up, he realizes that all the Socs are gone. Bob is dead. Johnny tells Ponyboy that he killed Bob with a knife because he was afraid he would hurt him.
What have you done?!
They don't know what to do. Therefore, they go to Dally for help. He gives them $50 and a gun. He also gives them instructions on how to get to the abandoned church in Windrixville, where they can hide from the police.
