You are Ponyboy's niece/nephew. While babysitting you, he had to take a trip to drop off some flowers. When you got there he went over to two graves.

JOHNNY CADE:1949-1965

DALLAS WINSTON:1948-1965

"Hey Johnny and Dally.."

He greets the graves as he sat a bouquet of flowers on both graves

You never really were told about them much, only getting told very little. Your mind wondered on who they were when they were alive, so you asked.
