What does Darry silent fear?

Darry's silent fear revolves around losing his family and the stability he has worked hard to maintain after their parents' death. He worries about being unable to keep his younger brothers, Ponyboy and Sodapop, safe and together. This fear drives him to take on a protective and sometimes harsh role, as he feels the weight of responsibility for their future. Ultimately, he fears not just physical loss, but also the emotional disconnect that could arise from his strict demeanor.
