After six episodes of the new Ncuti doctor and terrible ratings, they will have Tennant team up episodes, maybe even entire Tennant episodes to rescue a locked up 15th.
It’s all about ratings and however much money Disney paid BBC for their joint venture.
Charlotte Moore, BBC’s Chief Content Officer says: “We are thrilled to announce this exciting global partnership with Disney who are the perfect partners to bring this very British show to the rest of the world. Russell T Davies’ vision for Doctor Who has always been out of this world and we are committed to ensuring that audiences across the globe get the opportunity to enjoy the Doctor’s epic adventures with the scale and ambition that they deserve. Joining forces with Disney will elevate the show to even greater heights and reach new audiences so it’s an extremely exciting time for fans in the UK and across the world.”
Pure conjecture. Nothing in the quote substantiates your claim about Tennant returning. On the contrary, Davies has gone on record saying it’s not happening.
They are already prepping season 2 without any notion of future ratings, so your argument is completely unmoored from reality.
In fairness, RTD is well known to blatantly lie about what will happen in the future of the show.
“Blatantly lying” is … a strong term for RTD dropping teasers and red herrings without spoiling the show ahead of time. It does however describe OP’s claims pretty well.
