As I said before, things have gotten complicated with The Doctor and love, which is to say they could once again complicate further should Jodie Whittaker’s Doctor develop romantic feelings for Yaz.
While The Doctor was married to River in a complicated “timey-wimey” way, there’s an ongoing debate in the Doctor Who fandom regarding whether he had romantic feelings for Clara Oswald.
Whether that will actually happen in Season 13 or before Whittaker is done with the show, I cannot say, and even Mandip Gill hasn’t said one way or the other.
