The Promise

Blu-ray Trailer

Released: 3 September 2019

Like “24 Carat,” this is a trailer for the Season 26 Blu-Ray set. It shows a much older Ace in her role as CEO of A Charitable Earth, which has been mentioned in several other sources, reminiscing about the events of Season 26. At the end, the Doctor appears at the door and calls for her, although we only see his shadow. It doesn’t quite fit with "Dark Universe", but Ace is roughly the same age in both.
