Depending when you boarded the TARDIS, Doctor Who fans are always accustomed to the comings and goings of creative talent, most recently losing a fan-favorite companion, while Steven Moffat himself has waffled on remaining. Now, get ready to crank up the Peter Capaldi rumors, as the actor himself questions his future with the franchise.

Ahead of the coming Christmas special “The Husbands of River Song,” Capaldi spoke with The Telegraph of his iconic role, seemingly uncertain if he’d return beyond the coming tenth season:

This could be my final year – it’s terrifying. I love Doctor Who but it can be quite an insular world and I do want to do other things. There will come a time when this is over. But I knew that when I started. I was thinking about my regeneration scene from the outset. That’s my terrible melancholic nature. When you accept the job you know there’ll come a day, inevitably, when you’ll be saying goodbye.

The article also drew attention to a recent knee injury Capaldi suffered, alluding to his status as one of the elder actors to play The Doctor at 57, though Capaldi himself noted that Matt Smith suffered the same in shooting action sequences.

We’ll still have Capaldi back for Season 10 next year, presumably introducing a new companion after Jenna Coleman’s exit as Clara, but could The Doctor already be facing another regeneration? If and when it comes to it, what should the next Doctor be like?
