'Tis almost the season to be jolly, and Doctor Who fans have real reason to be jolly this festive season. The Christmas Special is almost upon us. Mysteriously titled Last Christmas, the episode is the first full-length appearance of Peter Capaldis Twelfth Doctor in a seasonal episode. Quite how his bleaker tones will work with the festive narrative remains to be seen, but after his sensational debut series he will no doubt nail Last Christmas. Despite parting ways when last we saw them, Capaldis Doctor is joined by Jenna Colemans Clara Oswald. Is this the beginning of the end, or just the start of a new chapter for this dynamic duo entirely? This is perhaps the most burning question many fans are wondering about, with many worries that Clara will indeed be departing for good. Well, you have less than a month to await the answer now. In anticipation of the upcoming special, here are you ten things you need to know about Last Christmas. This list will explore concrete information gleaned from official announcements, along with some pure speculation - just for fun. Steven Moffat has thus far failed to deliver a straightforward Christmas Special so you can probably expect this one to follow suit.
