WARNING: Game of Thrones spoilers ahead.

When Daenerys Targaryen learns of Jon Snow's true identity on this week's Game of Thrones, her reaction is dramatic—but not for the reason we expected. Yes, Jon does reveal to Dany that he's the son of her older brother Rhaegar Targaryen (and Lyanna Stark), thus making him her nephew; but she's less interested about the fact that they committed incest and more concerned that he now has a stronger claim to the Iron Throne that she does.

"If it were true, it would make you the last male heir of House Targaryen. You'd have a claim to the Iron Throne," she tells Jon tensely before they're interrupted by the Army of the Dead's arrival.

To be fair, this reaction makes sense for Dany. Ever since her first appearance in Season 1, she's been working her way back to Westeros, acquiring allies and armies to win back the Iron Throne that's been in her family line for generations. Jon, on the other hand, just found out he's a Targaryen in the last episode.

"There’s so much she’s seen and witnessed and been through and lost and suffered and hurt to get here… and Jon doesn’t even want it!" actress Emilia Clarke told Entertainment Weekly.

Dany finds out Jon’s parentage in Game of Thrones Season 8, Episode 2.

"The related thing, to her, is so normal," Clarke added to Entertainment Weekly, brushing off concerns that Dany has been sleeping with her own nephew. "She could have easily married her brother. It’s not a thing."

Clarke continued, "The main thing is we’re up for the same promotion and I’ve been working for it for my entire existence."

Meanwhile, Jon's reaction to that fact that he's in love with his aunt is a little more relatable. He didn't mention his relationship with Dany when Samwell Tarly hit him with the big reveal in the last episode, but it's still on his mind.

"What really upsets Jon is that he’s a blood relative to the woman he’s in love with," GoT screenwriter Brian Cogman told EW. "Jon is taken aback when essentially the first thing she says is acknowledging that he has a claim to the Iron Throne."

The Targaryen family has a history for incestuous relationships, but that doesn't mean it's a widely accepted notion in Westeros. Our O.G. brother-sister couple, Cersei and Jaime Lannister, have kept their relationship secret for years (although some nosy people in their circle know). Jaime even pushed a young boy out of a tower when he saw them together. (Hi, Bran Stark.) To top it off, their father, Tywin Lannister, was in denial when Cersei broke the news to him.

It's unclear how the information of Jon and Dany's kinship will affect their romance, but things don't seem to look so good for the pair going forward. The teaser for next week's episode shows them amidst a lover's quarrel as the Army of the Dead attacks Winterfell. "The dead are already here," Dany tells Jon frankly. Looks like their dragon-flying honeymoon phase is over.

Game of Thrones returns Sunday on HBO at 9 P.M. ET.
