Warning: Spoilers for The Robot Revolution ahead.
Ncuti Gatwa is back for his second season of Doctor Who, which has kicked off with a bang in The Robot Revolution, which viewers can now watch early on BBC iPlayer!
The episode introduced Varada Sethu's Belinda Chandra, the Doctor's new companion for season 15, who just wants to get home, but has to go the long way round when the TARDIS is unable to land there.
There may be a new TARDIS team in town, but that doesn't mean there won't be returning characters this season – in fact, the Doctor's previous companion, Ruby Sunday (Millie Gibson), is expected to show up later in the season.
Meanwhile, in this episode we're already seeing the return of the mysterious Mrs Flood (Anita Dobson) – but what is she up to?
There are also a host of new guest characters appearing in the episode, so read on for everything you need to know about the cast of The Robot Revolution.
