Answer:
What if Darry never slapped Pony?
In this alternate version of The Outsiders, Darry never loses his temper and slaps Pony. Without this incident, Pony doesn't run away and spend the night with Johnny and Dally at the church. Without the conflict between Darry and Pony, the story takes a different turn.
Without the added stress and tension between Darry and Pony, the three boys may not have ended up at the church that night. They may have all stayed at home, or perhaps Darry and Pony would have found a way to resolve their issues without resorting to violence.
Without the events at the church, Johnny may not have stabbed Bob and the Socs may not have come looking for revenge. This could have prevented the tragic ending of the novel, as Johnny and Dally may not have been caught in the crossfire and died.
Without the violence and tragedy, The Outsiders may have had a more positive ending, with the characters finding a way to resolve their conflicts and move forward in a more peaceful manner. However, it is also possible that the absence of the conflict between Darry and Pony could have led to other conflicts and challenges for the characters, resulting in a different but equally compelling story.
