Millie Gibson's character to be written out of Doctor Who?

Millie Gibson reportedly won't return for a second season of 'Doctor Who'.

The 19-year-old former 'Coronation Street' actress joined the show as Ruby Sunday, a companion to Ncuti Gatwa's Doctor, last year.

She made her first appearance in the 2023 Christmas special and will star in Ncuti's upcoming eight-episode season, which will begin airing in May.

However, it has been reported that Millie won't return for a second series and her character has been written out.

A source told The Mirror: "Millie Gibson has all but left now and there's a brand new companion, which is really exciting. [Showrunner] Russell T Davies is keeping things moving and isn't letting the grass grow, that's for sure."

Millie has been replaced by actress Varada Seethu, 32, who has already started filming in Cardiff.

A BBC source said: “Varada is a real gem, Russell was just blown away by her talent. The cast and crew have really warmed to her and he’s sure the fans will too.”

Speaking after landing the role, Millie said: "I will do everything to try and fill the boots the fellow companions have travelled in before me.”

Ncuti said: “Millie is full of talent, strength, she has a cheeky sparkle in her eye and is sharp as a razor. This adventure is going to be so wild and so fun, I cannot wait to sail the universe with Millie.”

And Russell commented: “It’s the great honour of my job to find the next generation of talent. As a 'Coronation Street' fan, I’ve seen Millie survive chases, guns and sieges, but that’s nothing compared to what lies ahead for Ruby Sunday.”
