Inside the Explosive Season 7 Finale

Jon Snow and Daenerys Targaryen's hot hookup was the talk of Twitter on Sunday night, after the Season 7 "Game of Thrones" finale ended with one steamy sex scene ... between an aunt and her nephew.

While the two still don't know they're related, fans at home finally got official confirmation as Bran and Sam reunited to reveal Jon's true parentage. Bran confirmed Rhaegar Targaryen (Dany's older brother) and Lyanna Stark (Ned's sister) were his parents, while Sam added the two were married before having Jon. It was also revealed that Jon's true name is Aegon Targaryen.

Executive producers David Benioff and D.B. Weiss talked about the show's latest incestuous tryst in a video HBO posted after the show, and what it means going forward.

"Just as we're seeing these two people come together, we're hearing the information that will inevitably, if not tear them apart, at least cause real problems in their relationship and she's his aunt," Weiss explained.

"It complicates everything on a political level, on a personal level and makes everything that could have been so neat and perfect for Dany, really muddies the waters," Benioff added.

Making the waters even muddier: there's a pretty good chance Dany's going to get pregnant from this bedroom romp, right?

Social media was ablaze with hilarious reactions as soon as the two hopped into bed with each other. See the best tweets below:
