They were at Dairy Queen eating lots of food since they haven't eaten food other than salami in a long time. When Dally informed Johnny and Ponyboy that there was a spy and they were surprised that is was Cherry.
While they were still eating Johnny tells Dally that they are turning themselves in and Dally wasn't too thrilled about it. Dally knew that the two boys caused trouble for the greasers already and he could just imagine what would happen when Johnny and Ponyboy go back into town.
While they were in the car Dally raised his voice the slightest to Johnny and since Johnny is quite sensitive he got sad. Dally didn't mean to hurt his feelings in any way he just didn't want him to go to jail and get hurt.
They have been driving for a while when the come across the church that they were staying at caught on fire with a small group of kids inside because there was a school group that went up there.
Everyone there was so shocked and nervous and didn't know what to do but Ponyboy risked his life and went into the burning church with Johnny following right behind him. The teacher tried to follow them but since they went through the window the teacher couldn't.
Ponyboy had fire on his back to Dally slapped him and Johnny blacked out. He woke up in an ambulance with the teacher. There was no sight of Johnny or Dally so he asked where they were and found out they were in a separate vehicle.
