I will fight someone in public over the time turner thing. No it's not a closed loop, yes they could've used it to kill Voldemort.
It's not a closed loop? It's been quite some time since I read the Prisoner of Azkaban but I was under the impression that was one of the limits.
It's supposed to be, according to the book, but what I mean is it doesn't make sense. The supposed explanation for why they didn't use it to kill Voldemort is "because they didn't."
Man, I was thinking about the gay Dumbledore thing, and the trans thing of course (JKR has very different conceptions of her characters than some of her readers do). Those are like national newspaper debates.
But not as interesting as the origin of the race of orcs and whether it’s okay to use a Qenya word in Quenya.
