Viewers discovered the true identity of River Song earlier this year in the mid-series finale, ‘A Good Man Goes To War’.

Speaking to CultBox recently, Darvill teased: “I think a lot of questions get answered in [‘Let’s Kill Hitler’]. You kinda find out how people are dealing with that revelation. I think it can only bring them closer together.”

He continued: “The fact that Rory is River’s dad gives him a certain authority which I don’t think he had before. It makes things far more complicated for them and far more complicated for Rory. He’s now been completely plunged into the world of it. As much as he wants a quiet life, I don’t think he can step back from it.”

Series 6 Part 2 kicks off with Steven Moffat’s ‘Let’s Kill Hitler’ at 7.10pm this Saturday on BBC One.
