Last Christmas scores Christmas number one, beating Sam Ryder and Mariah Carey:
"Wham!'s Last Christmas has been crowned this year's Christmas number one, 39 years after it was first released."
Prose The TARDIS Wiki page for Simon Guerrier's story is quite the thing, explaining as it does the background of the Kantian philosophy which underpins events, whether the murder of a baby who will go on to destroy a planet is justifiable, basically should be kill Hitler? Told mostly from Sarah Jane's point of view, we see all of the Doctor's incarnation up until that point attend the child's funeral, each on a mission to knife the thing in its crib with the Fourth Doctor brooding in the corner, biding his time. As ever it's the Eighth Doctor who does the heavy lifting. We know that the Time Lord can't do it, it's not in his nature, so it's a question of what he can do to nudge history in a different direction. Big Finish's Short Trips anthologies were often, quite, quite weird.
Placement: Charley's here, so the gap between the first two seasons.
Prose Does the Doctor have a celestial Google Calendar which pings him through the incarnations to return to certain places and catch up with whoever's there? The Glass Princess offers another example of this cross (re)generational story, as an event which happens during the Hartnell years, the poisoning of a young princess, becomes a mission as he returns throughout his life so he can wake her up now and then, for a few hours, so that her parents can spend time with her until she's the only one left of her civilisation. It's a similar effort to A Christmas Carol, with birthdays in for the 25th December and a group effort rather than just Eleventh.
The Eighth Doctor appears in the final scene, leading the girl towards her final moments. It is, as you might expect, horrendously sad and it's through his words the writer, Paul Leonard, articulates another element of the Moffat era, seven years earlier, that it's just a fairy tale, an articulation of Sleeping Beauty with the Time Lord in the role of the Prince. But honestly the section which really punched me in the gut is the moment when the Seventh Doctor gifts her a small blue badge in the shape of a boat which has been passed on by Ace who says she doesn't need it any more: "She said to tell you that you had deserved it. It's a badge really, not a brooch. It's only given to people who are very special. Very brave."
Placement: Outrageously, I think I'm going to retcon this in the Time War era, in the period when he's dealing with unfinished business.
Placement: During the EDAs perhaps? The Radio Times gap?
Audio Klein's Story dates from the period in the late 00s when Big Finish's monthly range, in an effort to make them feel snappier like the TV series, were split between a single episode story followed by a three-parter and this fills in the blanks on a narrative I've not otherwise heard related to an alternative timeline were, it seems, the Seventh Doctor and Ace accidentally caused the Third Reich to win World War II. It's rather like a companion chronicle or Short Trip with the (former?) Nazi relating how she managed to get her hands on a TARDIS.
In the course of events she meets that timeline's Eighth Doctor who's using the alias Johann Schmidt after having regenerated from Seventh who was gunned down whilst evading capture, his TARDIS already confiscated. In his dialogue, Paul McGann affects an ever so slight German accent but he's still the man he'd become in the main timeline, albeit following the plans set in motion by his previous self to rectify the cause of events which he (spoiler warning!) succeeds in doing whilst simultaneous helping political prisoners evade the Nazis. The Doctor hates fascists, no matter the timeline.
Placement: The newly renamed "Alternative Eighth Doctors".
