How does ponys realtionship change with Darry in the hospital?

In Chapter 5, when Soda and Darry come to the hospital, Ponyboy has a revelation. He sees his oldest brother cry for the first time in years - he didn't even cry at their parents' funeral - and realizes that "Darry did care about me, maybe as much as he cared about Soda, and because he cared he was trying too hard to make something of me." He understands that Darry is terrified of losing another person he loves, and wonders "how I could ever have thought him hard and unfeeling."
