Langford recently opened up to RadioTimes.com about Mel's role in the finale, saying: "Mel now has been basically spying in another job to gain information about an organisation that UNIT is quite worried about. And then the Doctor arrives because, you know, he's heard about things as well.
"And it all then literally cranks up very quickly. So Mel is able to, having infiltrated this area, offer up all that information and support and basically takes the Doctor on a Vespa. I know (laughs), it’s camp as hell – it is brilliant!
"And, and so basically she then is locked into this whole story of how to resolve what seems to be this mystery of stuff that's going on. Mel will go to the end of the Earth for the Doctor. She knows his history and also his love for the planet, the universe and everything involved is so genuine – it's so authentic – and she's just thrilled to be beside him again."
Where have I seen Bonnie Langford before? Aside from Doctor Who, Langford is known as a theatre icon, and starred as Carmel Kazemi in EastEnders from 2015 to 2018.

Explaining the switch, showrunner Russell T Davies said: "Lenny Rush was one of the voices of the space babies, and he’d been so good as a space baby voice that at that read through we kind of sat there and went 'It’s a shame. It’s a shame he’s just a voice and we’re not going to actually see Lenny.'
"So this chance came along to cast a new scientific adviser and I was like, 'Oh my God, let’s get Lenny'."
