What are The Outsiders incidents that reveal a change in plot or character?nope
One major reversal in character occurs in Chapter Twelve when the three Socs approach Ponyboy, Steve, and Two-Bit at the grocery store. Ponyboy reacts completely different to the Socs from his first interaction in chapter one; in this scene, Ponyboy busts the end off his bottle and warns the other boys, "You get back into your car or you'll get split" (171). Ponyboy describes feeling completely vacant--not "scared, mad, or anything. Just zero" (179). This is a huge change in his character from the beginning when Ponyboy feels truly afraid of the Socs; he fears getting jumped or having to fight them. His tough reaction shocks both Two-Bit and Steve, who worries aloud that Ponyboy has become like the rest of the gang, bitter and tough.
When Ponyboy sees Johnny and Dally both die all close to the same time, it makes him go a little crazy and he starts thinking that they aren't dead, he gets depressed and starts acting different. This is a change of character for him. Also, Dally goes and robs a convience store after figuring out that the only person he loves has died and doesn't see a reason to live anymore. This is a change of character for him.
