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.”
It’s gratifying to see how much the fandom — however split people are about this season — has embraced Mille Gibson, because she’s truly phenomenal.
I was worried when people ran with the “she’s being replaced” story (which they thankfully clarified) and started to go with a classic sexist “she’s hard to work with” story (which turned out to be that she got tired on night shoots, being basically an actual child when they started filming) that the fandom would pile on her, and I’m glad that people are recognizing her talent. However the character turned out, she was pretty flawless in the role. Delivering a performance like 73 Yards on your first week at a new job when you’re eighteen years old is pretty impressive.
