Millie Gibson hints at her appearance in Doctor Who season 14.
Speaking with RadioTimes, Gibson implies that she will be involved in Doctor Who season 15 in some way. In her interview, Gibson references “Ruby’s season two look.” Check out the full quote from Gibson below:
I think the sixties episode will blow people away. I think that’s my favourite personally. It’s a really cool episode with cool costumes. Any of the era episodes are always pretty iconic, aren’t they? It’s good because it’s usually only the companions that get new costumes but that season, the Doctor changes his outfit as well. I’m always blown away by the make-up team and the costume team, they’re so good. I love Ruby’s season two look as well. I’m so lucky.
Making Sense of Millie Gibson’s Doctor Who Season 15 Comments
The exact reason for her departure is unclear, but many former companions have had relatively short stints in the past.
Gibson’s commentary is somewhat confounding. It was previously announced that Gibson would be leaving Doctor Who after just one season. Along with this announcement, it was revealed that the actress would be replaced with Varada Sethu. The exact reason for her departure is unclear, but many former companions have had relatively short stints in the past.
Gibson’s Doctor Who exit seemed all the more final when production photos for Doctor Who season 15 were revealed. Said photos showed Gatwa with Sethu, Gibson’s replacement, running through the streets of a period set. These images did not include Gibson, and further confirmed Sethu’s active involvement in the series.

The news of Millie Gibson's departure from Doctor Who so soon after her debut has come as a surprise to many, but they shouldn't be surprised.
The commentary from the actress, however, indicates that Ruby Sunday will still somehow be involved in Doctor Who season 15. Perhaps, she could even be a part of the episode for which Sethu has been photographed. Time will tell how prominently Ruby will feature in Doctor Who season 15 after she departs as the primary companion.
