If you haven't gotten a chance to watch the Game of Thrones Season 7 finale yet, there will be plenty of SPOILERS below, so be sure to read on at your own risk. As is typically the case in any Game of Thrones season, the latest finale included some rather shocking revelations, including one scene that was quite controversial, and one that many other fans had been wanting to see all year. The two stars involved recently shed some light on what it was like to film this scene, but be warned, this is your last chance to avoid SPOILERS, so if you haven't watched the Season 7 finale, read on at your own risk.

Ever since production started on Game of Thrones Season 7, set photos had teased that the beloved characters Jon Snow (Kit Harington) and Daenerys Targaryen (Emilia Clarke) would finally meet for the first time. After returning to her ancestral home of Dragonstone, Dany summoned Jon Snow to meet with her, and throughout the season, as Jon remained in Dragonstone to mine the dragon glass needed to kill the white walkers, there was some sexual tension that developed between both Dany and Jon, and while fans know that Dany is really Jon's aunt, these characters don't know that yet, which lead to a steamy scene towards the end of the finale where Dany and Jon made love. HBO YouTube released a special behind-the-scenes commentary video with both Emilia Clarke and Kit Harington, where they both opened up about that scene, and what it could mean for the final season. We also get to see some of the disgusted reactions from the cast. Here's what Kit Harington had to say about this incestuous relationship below.

"I think its an inevitability from about halfway through the season that Jon and Daenerys will fall into bed together. I think they both know it's wrong. I think they both know it's going to cause problems. But it's that thing, when you suddenly feel that deeply about someone and you go through these events together, it's like a runaway train. You can't stop it from happening."

Emilia Clarke added that as actors filming a scene like that, "it's just weird," saying that they both might gag when finding out that they're actually aunt and nephew. Aside from the incestuous nature of their newfound relationship, these characters finding out the truth about Jon Snow's true heritage in Game of Thrones Season 8 will also be troubling in other ways, particularly for Daenerys. While Daenerys certainly does have a strong claim to the Iron Throne, Jon Snow is now the true heir, since he is the only male Targaryen left alive and the Iron Throne is passed down to the sons of the family. How this will affect Jon and Dany's new romantic relationship remains to be seen. People also caught up with Isaac Hempstead-Wright, who noted that Robert's Rebellion, which ousted the Targaryen family from power after more than 300 years, was all based on a lie.

"This whole thing that started off {Game of Thrones, the King's Rebellion, was a total lie. It's kind of like, mad, and what's going to be interesting is for Bran, it's like, 'What am I going to do with this?' because just as everything was coming together, everyone is coming together to fight, inevitably Game of Thrones will tear us apart."

The King's Rebellion, a.k.a. Robert's Rebellion, started when Robert Baratheon (Mark Addy) believed that King Aerys Targaryen's son, Rhaegar Targaryen, "kidnapped" the woman who was bethroned to him, Lyanna Stark, the sister of Ned Stark (Sean Bean). In the Season 6 finale, a long-held fan theory was proven true, when it was revealed that Jon Snow is actually the son of both Rhaegar and Lyanna, but this season gave us an extra added twist. While studying at the Citadel in Oldtown, Samwell Tarly (John Bradley) and Gilly (Hannah Murray) discovered an old maester's journal, where he revealed that he annulled Rhaegar Targaryen's first marriage, so that he could marry Lyanna in a secret ceremony in Dorne. While both Rhaegar and Lyanna ultimately died, they were both married, meaning Jon Snow was never a bastard after all, and since Rhaegar's first son was killed by The Mountain, Jon Snow is the one true heir to the Iron Throne. Hopefully we'll find out more about Game of Thrones Season 8 as we continue the countdown to the final six episodes, but until then take a look at this new video below with the stars reacting to this pivotal scene.
