What does Harry see when his connection with Voldemort is opened in the novel, Harry Potter and the Deathly Hallows?

Harry's scar starts to hurt, and he sees that Voldemort is angry. He is yelling at Ollivander. Ollivander is a wand maker who had told Voldemort to use another wizard's wand to overcome the connection between Harry and Voldemort's wand. Harry sees Voldemort magically torturing Ollivander, and then the connection is over. Hermione chides Harry because Dumbledore had told him to close the connection between their minds.
