Is Millie Gibson Leaving Doctor Who? RTD Reveals Ruby Sunday’s Fate (Spoilers)

The Series 14 finale of Doctor Who, “Empire of Death,” saw the departure of Millie Gibson as companion Ruby Sunday. Finally reunited with her biological mother, Ruby decided to depart the TARDIS and stay back on Earth.

However, this is not the end of the character. As some may recall, it was previously announced that Ruby will return sometime in Series 15.

Russell T Davies has now additionally explained that this marks a “pause” for the character. Varadu Sethu (previously seen in Doctor Who as Mundy in “Boom”) will join the TARDIS next year as the 15th Doctor’s newest companion.

Speaking to Doctor Who Unleashed, Davies said: “So that’s goodbye to Millie Gibson, except it’s not! You’d have to be mad to say goodbye to talent and a character like that!”

He added: “This is a pause. I genuinely felt Ruby’s story paused there. She couldn’t get all that information about her family, all that emotional overload, and run off in the TARDIS. It pauses there. She’s coming back.

“A new companion is coming in, but you’ll see the three of them together. Three people in this TARDIS fighting evil. There’s good stuff to come. There are really crucial stories for Ruby to come, and her family – the story of that family hasn’t finished yet – that will all make sense when you see it. So more to come.”
