Wherein Stephen Moffat takes our favorite companion in a generation and ZuZu's Petals her. But first we talk about the beautiful Picts vs Romans story, "Eaters of Light." Bill finds the 9th Legion and the Doctor finds an alien menace. And then they travel with Nardole and Missy toward a distress signal (the Doctor's theme tune) which winds up with Bill making a sacrifice and/or the Doctor failing to save his friends. It's a cliffhanger and we need a serious therapy session about it.

A New Doctor, a new Show Runner. The Moffat and Matt Smith eras begin. A crack in the wall has a little girl very scared, so scared that a Mad Man in a box doesn't rattle her at all.

The Monks Trilogy wraps up on a moody, atmospheric note with "The Lie of the Land," and Mark Gatiss wraps up his time as contributor to the show (Say it ain't so!) with the retro-Ice Warriors/Zulu tribute, "Empress of Mars." 

For the first time, many New Who fans experienced a Regeneration when the Ninth Doctor gave way to his Tenth incarnation, played by David Tennant. Rose returns home with a strange looking man who insists he is the Doctor, before he passes out.  Now the Earth is under attack by an alien race, and the Doctor can't be roused. Prime Minister Harriet Jones and UNIT try to handle the menace on their own, and Rose even gives it a go, but the Doctor wakes up just in time to play the role of Earth's Champion, even as he tries to figure out who he is this go-round.

Can you imagine the Pope arriving and spoiling a first date? This is Bill's life with the Doctor in it. Or is it real life? Or is it Moffat messing with us? Again? We react to Extremis, Missy's return, Nardole saving the day, Nardole with permission to dole out punishment, a pyramid that shows up out of nowhere, bacteria running amok and Bill doing what needs done to save the Doctor. And that's just the first 2 of a 3 parter!
