User blog:Abranon/When Harry and Dumbeldore went to the Cave, Was Dumbledore hoping to destroy the Horcrux, or bring it back to Hogwarts and destroy it there?

Dumbledore says that he and Harry are going out to destroy the horcrux, although once they have obtained what they think is the horcrux, why doesn't Dumbledore order Harry to destroy it with . Did he even bring the sword with him? And before Dumbledore drinks the potion, he does not tell Harry, what to do once they have drunken the potion. As they did not know what the affects were going to be on Dumbledore, if Dumbledore was paralysed, or forget about horcruxes or some other affect, Harry would not have known what to do with Dumbledore, what to do with the horcrux (he doesn't even know how to destroy them yet.) So what were their plans? This also makes me think about Regulus and his horcrux hunt, he presumably did not tell Kreacher, or even find out how to destroy them. It just seems like a plothole that they weren't prepared in both cases. What do you think?
