Doctor Who: The Power of the Doctor aired last night, and the episode concluded with Jodie Whittaker's 13th iteration of the iconic Time Lord regenerating into... David Tennant!?
Fans were wondering how Tennant's Doctor would factor into next year's new series, with many speculating that some sort of time-displacement or alternate reality adventure would allow him to return. Now, it's been confirmed that the Jessica Jones actor will be back for three new episodes as the 14th Doctor.
"What a lovely, lovely thing to get to revisit something that was such a wonderful, happy, significant time in my life," Tennant told BBC.com.
This means that Tennant's Doctor will eventually regenerate into Ncuti Gatwa's take on the character, who will officially be known as the 15th Doctor!
We also have a brief teaser for the new season, which gives us a first look at the Sex Education actor in the role.
Check out the promo below, along with the The Power of the Doctor's final scene and new stills featuring Tennant, Catherine Tate as the returning Donna Noble, and Neil Patrick Harris as the new series' mysterious villain.
