Yes, that is Doctor Who’s new season 2 companion in Boom – but the mystery cameo leaves us with more questions than answers

Some spoilers for Doctor Who episode 3 follow. You have been warned. 

‘Boom’ was an instant classic: a nerve-shredding, landmine-stepping trip to a planet caught in the middle of a never-ending war.

Doctor Who itself didn’t address it in the episode, save for a cute day-of-the-week quip from Ncuti Gatwa’s Doctor that she should marry Ruby Sunday (Millie Gibson) so they can be Mundy Sunday. 

There does appear to be a connection between the two companions present and future, though given the show hasn’t fully addressed the mystery behind Ruby and her snowy memories yet, there’s seemingly plenty of ground to cover before we bump into Varada Sethu again.

Moving forward, there’s probably going to be one of two outcomes: A) Varada Sethu returns as Mundy for reasons unknown as joins the TARDIS crew or B) Doctor Who pulls a ‘Clara’. 

The ‘impossible girl’ companion, played by Jenna Coleman, appeared twice as different iterations of the same character before joining the show full-time in 2013 – though her early appearance was part of a wider seasons-long narrative. 

Perhaps it’s the same again here. We’ll just have to be patient – the perplexing arrival of Mundy, it seems, is a story for another day.
