The Doctor's granddaughter has been teased on screen throughout this recent season, fan theories abound and original actor Carole Ann Ford has stated she'd be happy to reappear on the show.
Let's assume that there is a reunion with Susan coming up; that would be exciting in itself, but narratively, how do you think it will be set up? Does the Doctor seek her out or will Susan find her grandfather first?
More to the point, "the Doctor finally sees Susan again" is just a story beat โ how do you imagine the larger science fantasy story context surrounding it? Feel free to fanfic an entire episode plot or season arc if you want ๐
As much as they've been talking up the possibility that the Doc would actively go searching for her, I just don't think that's his style. Or maybe it's not the show's style - IIRC, we were told he went looking for Gallifrey, but we were not shown.
I'll leave the storytelling to the pros, but I imagine he'll either stumble upon her by accident, or she'll find him (likely in the nick of time).
And it would seem downright criminal not to hire Carol Ann Ford to play her.
I think the scene in Empire of death where the Doctor and Ruby debate her reconnecting with her mum is a template for his inner dilemma re Susan.
He says straight out to Ruby that her birth mother never reached out for "7000 days" so maybe she's not interested? That to me shows his own apprehension of not getting back in touch with Susan all those millennia (more than 7000 years in his timeline), but Ruby's instinctive decision to go meet Louise could show him that there is still time for him, too.
I mean, that's what I hope! And I completely agree, any reunion with Susan that doesn't include Carole Ann Ford would just not ring true.
