There was a surprise ending to the third episode of BBC's Doctor Who 60th Anniversary specials. Ncuti Gatwa's Fifteenth Doctor is pulled from the future.
David Tennant's Fourteenth Doctor and Gatwa's Doctor are split up in a rare case of splicing called "bi-generation."
People say that the episode's happy finish for Tennant's Doctor and Donna Noble was great. Tennant's Doctor can finally take a break while the next Doctor saves the world.
Fans would have expected the third part of BBC's Doctor Who 60th Anniversary shows to end in the way they did. Neil Patrick Harris's evil Toymaker killed David Tennant's Fourteenth Doctor,
who then came back to life as Ncuti Gatwa's Fifteenth Doctor. But... it wasn't that easy. Just like last year, when Jodie Whittaker's Thirteenth
Doctor turned into Tennant instead of Gatwa as fans thought, there was another surprise and twist.
Gatwa's Fifteenth Doctor was pulled in from the future wearing only a white shirt and underwear, which was a first for the long-running science-fiction show.
He was then split from Tennant's Fourteenth Doctor in a strange and unusual splicing event. There are now two Doctors, which is what the term "bi-generation" means.
