Don’t get us wrong—the latest development between Daenerys Targaryen and Jon Snow was pretty wonderful (aside from that whole she's-his-aunt, and he's-her-nephew thing). But what if the first love of Dany’s life, Khal Drogo, were to make a comeback?
It may sound crazy, but actually, this theory isn’t as out-there as you think. (Hey, we know from Jon’s own experience that resurrections are totally possible.)
Here’s the deal: Remember back in season one, when the witch Mirri Maz Duur seriously messed up Khal Drogo and left him in a vegetative state? Daenerys tries to bring her “sun and stars” back to life and asks Mirri when, if ever, Drogo will be as he was. Mirri responds, “When the sun rises in the west and sets in the east. When the seas go dry, and the mountains blow in the wind like leaves. When your womb quickens again, and you bear a living child. Then he will return, and not before.” Translation? Drogo is never coming back. Or, seven seasons later, is he?
Fast-forward to season seven's finale, and Daenerys and Jon are busy...getting busy. Dany goes on about her infertility over the last few episodes (her dragons are the only children she’ll ever have, yada yada), but what if that’s not what Mirri meant? What if she’s now pregnant with Jon Snow’s child? If that’s the case, then Drogo may well come back (because you know, Daenerys will "bear a living child").
