What four major changes and/or accomplishments do you predict for Randy's future in The Outsiders by S.E. Hinton?

Randy is different from the other Socs because he is willing to talk to Ponyboy, a greaser, and because he decides to stop fighting. He will likely not participate in any more gang activities and will go on to be a respectable citizen. Compared to other Socs, he will probably not drink as much and will be more accepting of greasers.

Randy is one of the Socs who attacks Johnny and Pony in the park. He makes a pretty dramatic turnaround after Johnny kills Bob. He asks to talk to Pony before the big rumble. He is impressed by Pony, Johnny, and Dally’s efforts to save the children at the church.

Randy tries to help Johnny and Pony by telling the police that Bob is the one who provoked the attack in the park.

Cherry Valance, and she said Bob had been drunk and that the boys had been looking for a fight when they took her home. Bob had told her he'd fix us for picking up his girl. His buddy Randy Adderson, who had helped lump us, also said it was their fault and that we'd only fought back in self-defense (Chapter 7). 

When Randy first wants to talk to Pony, he doesn’t want to talk to “the tall guy that had almost drowned” him. He listens to Randy, though, because he seems sincere. 

I'm sick of all this. Sick and tired. Bob was a good guy. He was the best buddy a guy ever had. I mean, he was a good fighter and tuff and everything, but he was a real person too. You dig (Chapter 7)? 

Randy feels terrible about what happened to Bob. He likely will not get drunk as often as he used to. He says what Bob did was wrong, but his parents were overindulgent.  This leads me to infer Randy will stop engaging in the behaviors he blames Bob’s parents for accepting, such as drinking too much, staying out late, and fighting.
