Steve, who was one of the first on scene, running to beat the life out of the socs who jumped Ponyboy, breaking his nose in the process.
Steve, who wants to keep Ponyboy from trouble, as he and Sodapop do reckless things & doesn't want to bring the youngest, vulnerable, and impressionable kid with them to do something like drag racing.
Steve, who is there as soon as Ponyboy comes home.
Steve, despite breaking 3 ribs, immediately looking to the door upon Ponyboy's return.
Steve, who watched in horror as Ponyboy broke that bottle and handled a group of socs on his own because he was scared of Ponyboy, the sweetest greaser, being like him.
Steve never hated Ponyboy, he just couldn't show Ponyboy that he cared. — Steve's character is one that I hold dear, as though his anger speaks volumes his actions speak miles. And though he doesn't have a role in the movie, his role in the book allows Ponyboy to sympathize with Randy.
Sodapop and Steve's friendship is a parallel to Randy and Bob, and without that relationship in the book, Ponyboy wouldn't have related to Randy's perspective.
People glance at Steve's character and only see him as a flat dynamic, however his character has more depth and personality than that, it's just we as the reader are in the same perspective as Pony. His depiction in both the movie and musical, though playing small roles, lets us observe the dynamic between Ponyboy and Steve throughout the book, and we observe Steve genuinely caring for the others in the story in his own way.
Steve Randle cared for Ponyboy just as much as he cared for Sodapop and the rest of the Curtis gang. I would go so far to say that they behave like the typical brothers you'd expect to see.
