The Cersei pregnancy bombshell was a shock, but there's another character whose pregnancy would be even more world-changing. Daenerys is certain that she cannot have any more children after the witch Mirri Maz Duur turned her unborn child into a monster (and her husband Drogo into a vegetable) back in season one. She emphasizes this multiple times in season seven, specifically to Jon Snow, who seems a little sceptical about the word of a witch. Fans theorize that not only is the idea that Dany is barren false, but that she will get pregnant . . . with Jon's child.
After what we learn about Jon's claim to the throne at the end of season seven, a child he has with Daenerys could cement a whole new Targaryen dynasty. If Dany does get pregnant, would that affect her reaction to Jon's true lineage? Would the fact that they have a child together keep her from going against him? And vice versa — if Jon decides he wants the throne, would he be able to go up against the mother of his child?
