Tell what these quotes mean: ( What are they talking about and why?)

Over the next four or five days, Ponyboy and Johnny kill time by playing cards and reading Gone with the Wind. Johnny becomes interested in the idea of gallant southern gentlemen, and says he thinks that Dally is most like them. Ponyboy is shocked, but realizes for the first time "the extent of Johnny's hero-worship for Dally Winston." They stay in the back of the church so they won't be seen by the rare passers-by.
