Continuing with Deathly Hollows

Harry potter stayed at the barrow for a while and he then went somewhere else, I am not going to ruin it for you guys but he had to go. Any way they had to go to grimauld place because that was the only place they could stay. Luckily there wasn't any death eaters and they where able to stay. Kreacher told them something that got their quest for the Horcruxes going.

In the book they keep saying that Voldemort is capturing wand makers.it keeps showing up again and again. I don't know why he would do that. I know about the twin core thing but he already has Olivander. I don't get it, I hope they talk about it later on in the book. I wonder if he is looking for a wand. I wonder if he is trying to get rid of the core and switch it.
