What is in store for Belinda Chandra?

Despite her previous appearance as Munday Flynn, Sethu is set to take on a new role in the Doctor Who Universe. We’ve not been told everything about nurse Belinda Chandra so far, but what we do know is that she will make her debut in the first episode of series two of the rebooted series.

The Robot Revolution will introduce Belinda as she crosses path with The Doctor after a group of robots kidnap her, mistaking her for their queen. And trying to get Belinda back to earth will lead the pair on adventures throughout the series.

Showrunner Russell T Davies told the BBC: "They are flung into outer space, and for all sorts of mysterious reasons that will be revealed as the series goes on, he can't get her home. He's got a time machine that can travel anywhere. But the one place he can't land is that day in May in 2025 when Belinda left the Earth, and that's going to be the ongoing struggle of the entire series – get Belinda home."

As well as trying to get Belinda home, former companion Ruby Sunday won’t be a stranger for The Doctor, with Millie Gibson set to reprise her role in a smaller capacity in the new series.

Doctor Who series two premieres at 6.50pm on Saturday, April 12 on BBC One. The episode will be added to BBC iPlayer from 8am, with the series airing internationally on Disney+.
