After a few days of staying in the church, Dally comes back and takes them to get some food. They didn't expect to come back to a ball of fire. The church was on fire and their were kids inside. Johnny was severely injured and left paraplegic.
Since forever, there's always been conflict between Soc's and Greasers. The Soc's were described as "White trash with Mustangs and Madras", while greasers are "White trash with long hair."
One day after a movie, two greasers, Johnny and Ponyboy, ran away and got themselves into some trouble.... they ended up killing a soc. However, the soc was trying to drown ponyboy.
Shortly afterwards though, Johnny died whispering the quote, "Stay gold," to Ponyboy. Johnny's death made Dally want to rob a store, just so he'd get shot by aiming a gun full of blanks at a police officer.
Scared, the two boys go to their other greaser friend, Dally, who gives them the address of an abandoned church to go to to get away from the fuzz.
The same night, there was a "rumble" or a fight for territory between the socs and greasers. The greasers fought hard and ended up winning.
