It was Leslie who had taken him from the cow pasture into Terabithia and turned him into a king. He had thought that was it. Wasn't king the best you could be? Now it occurred to him that perhaps Terabithia was like a castle where you came to be knighted. After you stayed for a while and grew strong you had to move on. For hadn't Leslie, even in Terabithia, tried to push back the walls of his mind and make him see beyond to the shining world-huge and terrible and beautiful and very fragile? {Handle with care-everything-even the predators.} Now it was time for him to move out. She wasn't there, so he must go for both of them. It was up to him to pay back to the world in beauty and caring what Leslie had loaned him in vision and strength.
As for the terrors ahead-for he did not fool himself that they were all behind him-well, you just have to stand up to your fear and not let it squeeze you white. Right, Leslie?
Right.
