Both Ponyboy and Cherry appear to epitomize the gangs to which they are affiliated: Pony's haircut, stance and closeness to his brothers contrasts with Cherry the cheerleader riding in cars with boozed up Soc's. However, each of them have hidden depths. Cherry chooses to discuss the sunsets they both share and Pony discusses his love of reading. They are able to open up to each other in a unique way.
A fourteen year old boy would be expected to have a crush on a beautiful seventeen year old who is prepared to talk to him, yet Pony seems more captivated by her honesty than any lustful desires. Similarly Cherry unexpectedly comments on how much Pony looks as handsome as his older brother, Soda.
Both Pony and Cherry can see that there is something beyond gang loyalty - sincerity, integrity and respect. These values can -and do - transcend gang loyalty for both of these characters.
