What would upset the newly pregnant Queen Cersei more than a younger and more beautiful woman coming to take her throne? A younger, more beautiful, and also pregnant woman coming to take her throne, which could be the direction Game of Thrones is headed if fans have their way. So after her long-anticipated boat romp with Jon Snow, can Daenerys get pregnant on Game of Thrones? At the end of Season 1, the idea of Daenerys ever having a successor to the Iron Throne seemed like a total impossibility.
After one of Khal Drogo’s men attacked him, the blood magic practitioner Mirri Maz Duur offered her services to help him recover. Unfortunately, she had ulterior motives on account of the fact that Drogo’s men had invaded her village to rape the women and steal their goods (you know, just Dothraki things), so her magic came with unexpected consequences for Dany. Yes, she technically saved Drogo from death, but the spell put him into a vegetative state. At the time, Daenerys had been pregnant with their son Rhaego, but her attempt at saving her husband resulted in her losing the child since it requited a blood sacrifice. "Only death pays for life," the witch explained.
In the end, Daenerys was forced to put Drogo out of his misery and was left with three dragon babies instead of the husband and soon-to-be son she’d had before. Mirri Maz Duur told Daenerys that she would have Drogo back "when the sun rises in the west and sets in the east. When the seas go dry and mountains blow in the wind like leaves."
In the books, Mirri Maz Duur added one final line, stating: "When your womb quickens again, and you bear a living child. Then he will return, and not before." All of this is the reason why Daenerys has believed herself to be unable to get pregnant again all these years. After all, when someone says something is going to happen when the sun rises in the west, it's only logical to assume that means it's never going to happen.
But, as Jon told Daenerys during Season 7’s finale Sunday night, maybe trusting a magic healer with a grudge wasn’t the best idea. And as she gave a little smile at that, the possibility of Daenerys getting pregnant on Game of Thrones increased ten-fold.
Even though Daenerys has believed herself to be unable to have children all these years, there are a number of things that might contribute to this miracle baby she and Jon may have conceived during their monumental boat sex. Since Jon is also a Targaryen, their shared bloodline might be the thing to break the witch’s prophecy. Or, since Viserion died, that could be a way that blood has paid for blood, thereby allowing new life to begin again in Daenerys’ womb.
If Daenerys get’s pregnant, it will give both her and Jon the heir they need to allow the Targaryens to live on. And now that viewers know for sure, beyond any shadow of a doubt, that Jon is a true born and legitimate Targaryen, the need for that heir Jorah alluded to in Episode 6 makes a lot more sense. In Season 7 Episode 6, Jorah advised Jon to keep Longclaw, the sword gifted to him by Jorah’s father before he died as Lord Commander of the Night’s Watch. He told Jon that he’ll need it himself and that (wink wink) his children after him will need it too.
Jon seemed to have an "ah-ha" moment as if he’d never really considered the idea of himself as a father anytime before that. Later in the episode, Tyrion urged Daenerys to consider what kind of successor she’d want to leave behind in the event of her death since, as she claimed, she can’t have children. A point she reiterated to Jon when he woke up on the boat and they shared that hand holding session felt around the world.
Take all of those cleverly placed mentions of Daenerys having children on Game of Thrones — and add in the fact that Daenerys and Jon had sex during Bran’s creepy voiceover while he discussed Rhaegar and Lyanna falling in love and conceiving Jon — and it’s clear that this is the goal.
Now, I don’t think Westeros in its current state is any place for a baby, but if Jon (ahem, Aegon Targaryen) and Daenerys had sex, it’s bound to produce an heir to allow their family name to live on.
