it’ll be both amazing (because I love Maisie and I love River so i’d love it) but I also really adore Alex as River so i’d be kinda sad it wasn’t her.
Exactly this. But I think, in the end, she can either be River/Jenny (the Doctor’s daughter), or a new character who has met the Doctor earlier in the episode. I doubt it’s a Classic Who character like I’ve seen other theorising.
