Well as I said last week, Doctor Who tends to introduce a new companion (and even new Doctors, come to think of it) with a specific trio of episodes, and although a couple of companions (Martha and Donna) got their historical episode before they went into space, Bill follows the majority by getting her trip to the past in her third episode. And unlike the space episodes, "Thin Ice" has some generally decent ones to follow. Fortunately it's the third hit in a row in Steven Moffat and Peter Capaldi's final series.

"Thin Ice" by Sarah Dollard, directed by Bill Anderson. Spoilers after the cut.

Raven? See, moan.

So after Doctor Who Series 9's only single-part story we go into a concluding three-parter, but a stealth one, a bit like "Utopia" was a stealth way to reintroduce the Master. In this case it's the Time Lords who are reintroduced, and they're grumpy about... something, because the Time Lords are always grumpy about something.

"Face the Raven" / "Heaven Sent" / "Hell Bent" by Sarah Dollard and Steven Moffat, directed by Justin Molotnikov and Rachel Talalay. Spoilers after the cut.
