Allie Caulfied

Allie is a supporting character who isn't physically in the book: his "inner desires" are not explored. Allie Caulfield is Holden's younger brother, Allie died from leukemia. Holden often reminisces about Allie, particularly about his baseball mitt, which Holden uses as the subject for Stradlater's essay. Holden adored Allie, but when Allie died, Holden lost his capacity to truly love without fear. The idea of putting his heart on the line for someone who might disappear has become Holden's crucible--and the consequences of shutting down have left him numb.
