His new companion Bill Potts asked the question on many viewers’ lips after the Doctor first spoke about the promise which has kept him on Earth for so many years.

In the second episode of the series, titled Smile, the Doctor said to Bill: “A long time ago, a thing happened.

“As a result of the thing, I made a promise. As a result of the promise, I have to stay on Earth. So.”

Bill pointed out: “Well  you’re not guarding the vault right now.”

The Doctor said: ” Yes I am. I have a time machine, I can be back before we left.”

When Bill asked: “But what if you get lost, or stuck or something?”

The Doctor paused and replied: “I’ve thought about that… Well, it would be a worry, so best not to dwell on it.”
