Doctor Who Series 10: 13 Easter Eggs & References You Might've Missed In 'The Pilot'
3. Friend From The Future
The scene where the Doctor and Bill are hiding from the Daleks in futuristic corridors should definitely ring a bell. It's the same scenario and setting as that from the specially-filmed clip, known as Friend From The Future, that introduced Pearl Mackie as Bill to the world. It was first released last April during the half-time break for the FA Cup semi-final.
Even better for us obsessive fans is that the scene very neatly slots into this episode. Things begin to play out the same way here as Bill starts questioning the Doctor on the Daleks. We then jump cut to the end of the scene, as the pair run through another corridor.
Writer Steven Moffat explained to the Doctor Who Youtube channel that the episode originally contained the whole scene but, within the context of the rest of the story, it presented Bill as "too new" so it was cut.
