In December 2022 I wrote about the surprising return of David Tennant to Doctor Who, and made a prediction about the theme RTD wanted to explore:
It is my expectation that this return to the role of Doctor is explicitly intended as a continuation of this thread: RTD will frame this as the Doctor’s own psyche giving himself a chance to resolve his resentment and frustration, come to terms with the end of his time as Doctor, and to accept his final regeneration with positivity (just as the 13th Doctor managed to do).
So I think we will see the marvellous Bernard Cribbins (RIP) again, as it was his life Tennant’s Doctor died to save beforehand. And I think his Doctor’s final line will be a satisfying rejoinder to the words that ended his previous incumbency:
“I’m ready to go.”
What we got in November 2023 was:
Close enough!
