Doctor Who: Every Multi-Doctor Story Ranked Worst To Best

Well, it's safe to say that nobody saw that coming. Unless you saw the leaks. But hopefully you didn't!

Upon facing the Toymaker atop UNIT Tower in the final 60th anniversary special, the Fourteenth Doctor is shot and presumably killed by his accent-changing foe.

Just when everybody was teary-eyed, getting ready to say goodbye to David Tennant all over again, RTD played the ultimate bait-and-switch by having Fourteen "bigenerate" into Fifteen.

This means that, in the words of Nute Gunray, "This is getting out of hand! Now there are two of them!"

Fourteen and Fifteen stand side-by-side, wardrobe split neatly in half, ready to take on the Toymaker in one final game. Though they're only together for a short time, these two Time Lords break new ground for Doctor Who, and their interactions are perfect – Gatwa playing the older mentor role to Tennant's tired soldier.

Elsewhere, there's a brilliantly bonkers turn from Neil Patrick Harris, several thrilling set pieces, a killer musical number, and a satisfying ending that puts a neat bow on the past 60 years, with both eyes firmly on the future.

Will having two Doctors running around cause massive headaches further down the line? Maybe. But for now, let's all just bask in the utter madness of The Giggle, and be thankful that we didn't have to cry like it was 2010 all over again.
