It is the end of an era in more ways than one. Doctor Who is preparing to go into yet another phase (one that we truly believe is the Bad Wolf era) with another “clean slate.” Fans are bidding a sad farewell to the Thirteenth Doctor, Yaz, Dan, and showrunner Chris Chibnall in “The Power of the Doctor,” which will air on October 23. This story has been pretty hush-hush since its announcement until “The Power of the Doctor” trailer hit us all with those complex regeneration feels as Thirteen gets ready for her last episode. 

Of course, it is exciting to see the return of Sacha Dhawan’s very hot Master, along with Vinder and Kate. And we get an extra treat for Thirteen’s sendoff with Classic era companions Ace and Tegan! In The Power of the Doctor clip, we hear the Master (who looks a bit scraggly) tell the Doctor that her life is coming to an end. She teams up with Kate to go searching for missing seismologists, which brings her back across the path of Ace once again.

One thing is for sure…this Doctor is very different from the one that Ace was with decades ago. Oh yes, and there is a Dalek incursion happening because there’s always some mess with the Daleks. Those guys will outlive us all. The Doctor Who trailer ends with that dreaded moment of regeneration energy surging from a very scared Doctor’s face. It is always hard to say goodbye, but we are all very curious to (presumably) get our first glimpse of Ncuti Gatwa as the Fourteenth Doctor. Seeing him in Thirteen’s delightfully colorful outfit will surely spark a lot of joy.

“The Power of the Doctor” certainly gave us a hype Doctor Who trailer full of questions, fire, and what could turn out to be yet another heartbreaking swan song for our beloved time traveler. Let’s see how it all goes down and prepare ourselves for the big feels as Thirteen’s last episode hits our screens.
