This isn't in response to anybody here but I'm totally happy with characters who weren't in the books. I'm serious.
Why couldn't one of the Carrows have had twin daughters? Huh?
They needed some slytherin characters for a scene. So they created some based off of one who is in the books. And. They. Had. Every. Right. This isn't even our first look at these two, so why are some people complaining now?
I don't understand the haters.
