Questioner
I never understood why Vin couldn't hold the Ruin Shard.
Brandon Sanderson
I could see a world where Vin maybe could have done it. But the trajectory she was on was opposed to it. Vin could have understood and become it. But what are the things that are keeping her? Vin, I don't think accepts, number one, that decay has to happen. She's experienced it a lot. But there's that piece inside her that doesn't want that to happen, doesn't want things to change, does not want people to leave her. I think that would be--if you read through, that's the soul, sort of, center event is, "Don't leave me, don't go away, don't change." And this is diametrically opposed to Ruin. People focus on the fact that she's good at killing and she is. But that heart, that soul...Ruin is more about things changing and decaying, than even about destroying.

And I guess that's the reason why she can hold Preservation very easily?
Brandon Sanderson
Yes.
