When Charles and Camilla visit the Middletons, the simmering tensions threaten to turn violent. Fergie and the girls go to Glastonbury. And Meghan catches Harry in a compromising position with Pippa.

Charles vows to prove he's not a crank. Wills wants his Duke of Edinburgh award. And Meghan realises Kate's been replaced by a robot - but who is the real duchess?

Charles officiates at the Church of Satan. Wills is tricked by his builder. Chalet girl Beatrice catches the eye of an eligible bachelor. And Harry does a deal with his doppelganger.

Kate worries she's boring. Beatrice and Eugenie are offered millions to be the face of a perfume... if they cut ties with Fergie. Anne invites David Beckham for a sleepover. And Meghan's had enough.

Donald Trump asks Charles and Camilla to be King and Queen of America, but Wills thinks something fishy is going on. Harry hires Pippa as a nanny. Meanwhile, who will walk Beatrice down the aisle?
