Voldemort watched with great interest as Ollivander pulled down the first wand. Holly. 10 1/4". Dragon Heart String core. He didn't even bother touching it, instead He knocked it to the floor. He resisted the urge to torture Ollivander for such incompetent choice. He needed Ollivander at full wits to deliver the best wand.
Over the course of the next several minutes, the wand choices increasingly improved. He tried holding them all, but none of them responded the way His old wand did. So He ordered Ollivander continue.
It was becoming a difficult needle to thread. On the one hand, He didn't want to leave without the best possible wand. On the other, the longer He stayed the more likely He would be disturbed. And this mission had to succeed. He had already heard two people exclaim bewilderment at why they couldn't access the shop.
