“Even the mystery of the silver doe, which the other two insisted on discussing, seemed less important to Harry now, a vaguely interesting sideshow. The only other thing that mattered to him was that his scar had begun to prickle again, although he did all he could to hide this fact from the other two. He sought solitude whenever it happened, but was disappointed by what he saw. The visions he and Voldemort were sharing had changed in quality; they had become blurred, shifting as though they were moving in and out of focus. Harry was just able to make out the indistinct features of an object that looked like a skull, and something like a mountain that was more shadow than substance. Used to images sharp as reality, Harry was disconcerted by the change. He was worried that the connection between himself and Voldemort had been damaged, a connection that he both feared and, whatever he had told Hermione, prized. Somehow Harry connected these unsatisfying, vague images with the destruction of his wand, as if it was the blackthorn wand’s fault that he could no longer see into Voldemort’s mind as well as before.”
