'Game of Thrones' showrunner teases Jon Snow's Season 8 journey

A lot of shit is scheduled to hit the fan when Game of Thrones Season 8 premieres in April, including revelations that Jon Snow and Daenerys Targaryen – military allies and newly-minted lovers! – are aunt and nephew.

The actors discussed the weight of this information with TV Guide, as did showrunner D.B. Weiss.

"From a dramatic standpoint, it makes things interesting, because the story is no longer about who Jon’s parents are,” Weiss said in the interview. “It’s about what happens when Jon finds out.”

As fans have suspected for years, the Season 7 finale confirmed that Jon Snow is the son of Rhaegar Targaryen and Lyanna Stark – a son called Aegon.

“Jon is someone who plays by the book. He cannot lie,” Harington said (a fact we've seen demonstrated and weaponized by the Night's Watch). “Finding out about Dany would be very hard for him.”

Not to mention that Daenerys has built quite a lot of her reputation on being the last living Targaryen – a direct successor to the throne in whose veins flows the blood of dragons.

“Daenerys’s lifelong dream has been to avenge her family and claim her rightful seat on the Iron Throne,” Clarke said. “She truly loves Jon. Were she to find out about his title, it would cut deep.”

This sounds highly foreboding for Westeros' new incestuous power couple (sorry, Jaime and Cersei!). But will it destabilize their relationship before or after the Army of the Dead destabilize all life? Will it somehow remain a secret? Worst yet...will Cersei get to the news before they do?

We'll find out when Game of Thrones returns in April.
