Patrick Ness has said that his Doctor Who spin-off “Class” will not rely on bringing back old favourites.

“I want to show the world new stuff,” Ness told EW. “I want to have new things that maybe we haven’t seen before. That’s my goal. That’s what I’m aiming for — shock you with something new. Something like the Weeping Angels, which I think are great, are brand new. Steven Moffat invented them a couple seasons ago. There’s not going to be any Weeping Angels on Class, but I’m just saying that they’re something new to the Doctor Who universe that are just awesome, and I would like to do that.”

Speaking more generally about the show: “The idea is to take everything that I love about YA, which is the great breadth of it and the great depth of it and its fearlessness about the emotional stuff and its fearlessness about emotional truth, and the way that it takes teenage characters seriously as complex human beings, and just put that on television in the Doctor Who universe, and that sounded very, very exciting to me”

On who the show is aimed at: “It’s extremely important for teenagers, and that’s who it should be for first, but the best YA reaches beyond that,” he says. “The best of anything reaches beyond its boundaries.”
