Ser Davros, who took the throne and opened his eyes for the first time. He cried, but it was because he was cutting onions. He is the onion knight after all

Meanwhile, Mayor Me is over the narrow sea having an existential crisis as well.

Meanwhile, Jorah had enough of Dany rejecting his advances and went to marry River Song. Gendry finally stopped rowing when he ended up on a planet of clone people. Walder Frey went into hiding and purchased a ship full of dinosaurs. In the season finale, Grand Maester Pycelle will finally reveal his true colours as the last of the Jagaroth.

They were always going to return, outside of a few of the Doctors the Daleks probably sell the most merchandise.

Yes, i'm that cynical

Not to mention the head of the iron bank got bored and wanted a career change... got into genetics and became Professor Lazarus.

And Jaqen H'ghar/Sexy Jesus was so devastated when he lost 'a girl' that he went and joined the Third Reich and appeared in The Sarah Jane Adventures.

And that Maester Luwin faked his death and went and became President Rassilon of Gallifrey. He's still actually Maester Luwin... he's just pretending to be Rassilon and everyone buys it because all he has to say is that he regenerated. Buys a round for everyone at the Citadel Tavern, tells a funny little ice-breaker about how he always gets mistaken for that bloke Donald Sumpter, and people just love the guy!

Actually that'd be quite an interesting story idea come to think of it Someone who pretends to be a particular Timelord or other and hides their real identity by simply claiming that they regenerated.

I didn't actually know about the Jaqen H'ghar one. It's very interesting seeing the abundance of actors that are shared between Doctor Who, Game of Thrones and Harry Potter. :P

Meanwhile, conflict is rife between Amy and Rory since they went their seperate ways to join Marvel and DC, respectively.

Looks like someone's finally invented the MK1 travel machine:

Of its three principle features, I think we can all guess what the "two fingered gripper" will be replaced by for the MK2. I suspect the sucker cup and eye stalk will remain, however...
