Doctor Who showrunner Russell T Davies says season 2 is ending with the introduction of a brand new villain - to round out the Unholy Trinity.
"NEXT WEEK: Wish World. Enemies old and new unite as the Doctor faces the Unholy Trinity. This is only two thirds of the Trinity, the two Ranis count as one, cos I say so," Davies wrote on Instagram. "The third is lying in wait, exactly 160 years away. So stand by! This is the big one! First of a two-part finale! The Pantheon is stirring. Old friends are helpless. And the whole of reality is in danger as we hurtle towards May 24, in the Ranis' most terrifying experiment yet."
