Darry had one action that affected a lot of the story when he slaps Pony. When Pony yelled at Darry, Darry wheeled around and slapped him, causing Pony to run away. If Darry only yelled at him, Pony wouldn't have run away, and he and Johnny would not have met up with Bob's gang. The result of Darry's slap and how it affected Pony can be seen in his shocked thought when he expresses, "Nobody in my family had ever hit me" Darry was angry at Pony and Soda (50).
When looking at the church Pony and Johnny had run off to, they notice it is on fire. They find out there are kids in there and go in to rescue them, but doing so, Johnny gets critically burned and is rushed to the hospital. The fire resulted in Pony going to the hospital, too. His brothers meet him there and Pony says "Suddenly I realized, horrified, that Darry was crying" (98). Darry doesn't say anything but Pony knows he is sorry. The church fire is a significant part in this novel because without it, Pony wouldn't meet back up with Darry.
After the church fire and the rumble, Pony and Dally rush over to the hospital to see Johnny, dying. Johnny tells Pony in his last words "Stay gold, Ponyboy. Stay Gold" (148). Johnny's death caused Dally to rob a grocery store, and get shot by police, basically committing suicide. Ponyboy gets sick after seeing to of his friends die and ends up staying in bed. He then picks up a book called Gone With the Wind. He sees a note from Johnny and thinks about how people think that they hate the world, but there is still good in it.
