Hey. I have a question about "The Catcher in the Rye"?

I feel he was already the catcher. I feel the hat represents the catcher in the rye. Who posessed it was the catcher. After he gave Phoebe the hat he kept feeling like he was going to fall when he came to each block and he was asking his dead brother Allie to prevent him from falling putting his dead brother in the position of the catcher, but there was no real danger of him falling he was just being crazy for lack of a better term so there was no need for a catcher. The real problem he faced with falling was falling into obscurity like Mr. Antolini had talked to him about. When Phoebe had the hat she rescued Holden from running away to the west and then he decided to stay (caught him from falling into obscurity), at that point she gave the hat back to Holden as she went to ride the carousel at which point he was watching her and decided he would stick around to protect her. Becoming again the catcher in the rye because his concern was to make sure to protect his little sister. I feel this goes well with Berraks theory because he was caught by Phoebe, and decided to stay and then and then ended up in the institution where he was helped further. That leads me to disagree with Krypton, it doesnt mention any medicines or anything but it mentions the psychoysts which makes me think its more of a talk through his problems situation and it talks about where he will be going to school in the fall so he wont be having a stay longer than a year there. So I feel he will continue to be a catcher in the rye because he had been off and on through out the story.
