Peter Capaldi recently gave some more spoilers about the Doctor Who 2016 Christmas Special. He says it will be “nostalgic” and will call back to when superheroes were “ironic and witty and clever.”

Spoilers reveal that Doctor Who’s “The Return of Doctor Mysterio” will begin with a child meeting the Doctor. Because of this experience, he’ll grow up to become the superhero The Ghost. He will also have a relationship with the journalist Lucy.

Matt Lucas will also be back as Nardole on Doctor Who. He, of course, had his head removed the last time we saw him. But predictions say that the Christmas Special will reveal what happened to him.

“I’m just a little bit calmer and a bit less shouty,” Lucas said of his Doctor Who character. “He’s often the one asking the question because he doesn’t really understand things, and I think kids might be doing the same thing. But then very occasionally when you’re least expecting it, he says something really clever. He’s different than me in that regard.”

Nardole will also appear on Season 10 of Doctor Who. And that's when we'll finally meet the Doctor’s new companion, Pearl Mackie’s Bill. We may see Missy or Clara again, as well.

Capaldi also said that there will be “Romans” in Season 10. So there are rumors that the Doctor will reunite with Amy and Rory, or the famed emperor Nero. He could even encounter Caecilius, the Roman man who was portrayed by Capaldi back in Season 4.
