Like Jo Grant Returns before it, this was a narrative trailer, set around the present day, featuring a companion from the season, here Ace as played by Sophie Aldred, who has now long since departed the Doctor's company.
Ace thinks about what happened thirty years ago. How she was just a kid who thought she knew it all when she met him and he showed her the universe full of adventures: monsters, demons, friends, enemies, fights, justice and so much more...
The Doctor and Ace... teammates.
When suddenly, he let her go to make the world a better place. She says she loves what she does for a living now. But that she some times still look for him from her office-window because he left her with a promise that he would return one day.
Ace grabs onto her trademark jacket and heads out the door of her office.
