Vision: It's starting to look as if Twilight isn't especially interested in curing herself of her case of being a horrifying abomination. Also, I'd be kinda worried about Colgate in case this is contagious or something.

Originality: It's good to see certain elements of the "Always Connected" story line in this one; even if it isn't connected to that story, it's similar enough that we know what to expect.

Technique: Showing us what Twilight is thinking during the chapter helps us see that she's starting to turn into something pretty much monstrous and starting to not question it.

Impact: I really am kind of worried about Twilight right about now. She might not want to solve this after all.
