The latest trailer for Doctor Who shows us more than just a teaser. Just a little.
It tells us a lot more. That voice is familiar. No spoilers. Watch if you want; you’ll know who it is. You’ll also hear that the speaker likes the darkness they think they can see in the Doctor.
We know that darkness is there. Remember the episode with the Dream Lord? That was before the Doctor spent years at war and had to watch loved ones die.
