Steven Moffat has left the idea doubtful but open - but at New Orleans Comic Con recently, Matt Smith stated that he doesn't want River to return alongside Capaldi.
Smith said to fans at a panel at the convention:
"I'm really possessive about Alex [Kingston]. I said this to Steven, I was like, 'Listen, just don't. Just not Alex. Anyone else, but don't give him River' - but Peter is the Doctor now so hey, what can I do? I think that Steven will be planning things that are going to unfold over years. I think he'll reinvent the folklore, and it will become Peter's folklore.
What do you think? Do you want River to return alongside Capaldi's Doctor, or do you want her appearance last year to be her final one? Leave a comment below!
Series 8 airs later this year on BBC One.
