It finally happened. After weeks of exchanging significant glances and longing looks, Daenerys Targaryen and Jon Snow threw caution to the wind and hooked up on the high seas in the Season 7 Game of Thrones finale, "The Dragon and the Wolf." Everyone and their uncle might have seen it coming (and in case you didn't, the show made sure to remind you by having both Davos and Tyrion remark on Jon and Dany's visible thirst), but people are still freaking out over Jon Snow and Daenerys having sex on Game of Thrones. And really, who can blame them?
Jon and Dany's hookup comes as absolutely no surprise since they've been swooning over each other ever since he first sailed up to Dragonstone. They may have disagreed at the beginning, but they quickly came around to the same side once Jon bonded with Drogon and again when Dany got a glimpse of the White Walker army. They understood the threats at hand and they understood where the other was coming from, even if it left them ever so slightly at odds. There's also narrative significance to their relationship, because they each serve as representatives of the show's fire and ice theme. Their first meeting was seven seasons in the making, and it was only a matter of time until they took things to the next level.
Fans have been looking forward to seeing Jon and Dany on screen together for a long time, so it's understandable that viewers would totally lose it once Jon and Dany let passion overtake them. This relationship is a big deal for the series, even if some members of the fandom (cough cough, me) aren't feeling it quite as much as others.
With Jon and Dany together, everything falls into place. The south and north are reunited once again if the rightful heiress to the Iron Throne gets together with the King in the North. They can now form a united front when they take on whatever new threat comes their way, whether it's someone else after the throne or a White Walker looking for trouble.
That doesn't mean that there won't be any trouble for Jon and Dany, however. Just because they slept together doesn't mean they'll immediately be taking a walk down the aisle. Dany has always been careful when it comes to considering what makes the most political sense for her, like when she left Daario behind in Meereen so that she could keep her options open in Westeros. She may decide Jon isn't the best idea, even if she does want to be with him.
And the truth about Jon's parentage could present a problem for them, too. Isn't it such a downer when you realize the hottie you just hooked up with is actually your nephew? Jon is the child of Dany's older brother Rhaegar, which could be tricky for two reasons. Dany might be down with incest as a Targaryen, but Jon's Stark sensibilities could mean he might not share that opinion.
Jon also has a better claim to throne than Dany does. In Westeros, the throne passes down through the eldest male children of the family; Rhaegar was next in line after Aerys and Jon would be next in line after Rhaegar. Children take precedence over siblings in this case. Marrying Jon would neutralize that conflict, but killing him would do that too. Decisions, decisions.
But Jon and Dany can cross those bridges when they come to them. In the interim, fans of the couple can rejoice.
