How does Dally's decision to leave the Nightly Double change the setting of chapter 2 of The Outsiders?

1) It makes the setting less interactive because Ponyboy and Johnny are too shy to talk to the girls.

2) It makes the scene at the drive-in less threatening to the Soc girls, and they can talk more freely.

3) It makes the setting more stressful because Dally will bring back other greasers who will start a fight.

4) It makes the scene at the drive-in less safe with only Ponyboy and Johnny around to protect the girls.
