The movie comes to an end and the group decides to walk over to Two-Bit's house to get his car to take the girls home. Two-Bit and Marcia continue to get along, and as they walk Ponyboy and Cherry amaze themselves as they divulge insights as confidants.
Cherry shares her philosophy on what separates the two gangs — not only money but passion as well. The Socs lack strong emotions; they are cool almost to the point of not feeling. Ponyboy is amazed, though, at how similar the two gangs really are; they share a "basic sameness." However, Ponyboy does concede that the two groups' emotional responses to life are different: "It's not money, it's feeling — you don't feel anything and we feel too violently."
As the new friends — Pony, Johnny, Two-Bit, Cherry, and Marcia — walk, a blue Mustang passes, a car that the girls identify as belonging to their boyfriends, Randy and Bob.
After a moment of tension, the car continues on its way and the group continues their walk. Ponyboy and Cherry resume talking and Cherry asks Ponyboy about Darry. He explodes and complains bitterly about Darry and concludes that he knows that Darry does not like him. Two-Bit and Johnny are stunned. They defend Darry, which only infuriates Ponyboy, so he verbally attacks Johnny about his own terrible home life.
The blue Mustang returns and this time it stops. Two Socs get out, and Ponyboy notices that one of them is wearing three heavy rings. Ponyboy puts the blue Mustang together with the rings and realizes that this is the group that attacked Johnny. Johnny stands terrified. A fight is threatened, but Cherry puts a stop to it, and the girls leave with the Socs.
Two-Bit heads off to hunt up a poker game and maybe to get drunk, and Johnny and Ponyboy decide to lay down in an empty lot and watch the stars. After a rambling fantasy of Ponyboy's — in which he visualizes the perfect life in the country, free of gangs and with his parents still alive — the boys drift off to sleep.
Johnny awakens and sends Ponyboy home, whereupon Ponyboy discovers that it is 2 a.m. Darry has been waiting up for him and is furious. Darry slaps Ponyboy and instantly regrets it. Ponyboy now knows for sure that Darry doesn't want him and runs out the door followed by Darry's cries of regret.
Pony heads back to the vacant lot, wakes Johnny, and announces that it is time for them to run away. Johnny tries to calm Ponyboy. Johnny points out that Ponyboy is lucky to have family who cares about him, and that the gang members never really take the place of family in Johnny's life. They walk to the park, and Ponyboy decides to return home after cooling off a bit.
