Warning: Spoilers ahead for the "Game of Thrones" season seven finale, "The Dragon and the Wolf."

One of the biggest head-scratching moments from the "Game of Thrones" season seven finale was when Tyrion stood, looking disgruntled, outside of Daenerys' ship cabin. He was presumably hearing Jon and Daenerys have sex for the first time, and clearly this displeased him.

But why? People (myself included) speculated that Tyrion was simply wary of the possible conflict the romantic union of Jon and Daenerys might trigger. During INSIDER's interview with the episode's director, Jeremy Podeswa, he expanded on Tyrion's mindset in this scene.

"I think it's a combination of things," Podeswa told INSIDER. "Jealousy is too simple, in a way. I think what's really going on here for me is that Tyrion is a strategist. He's somebody who thinks to the future and what the consequences of things are. For him, the union of Dany and Jon is a bit of a monkey wrench in terms of the plan for how they're going to move forward in a united front against the army of the dead."

Jon and Daenerys should definitely be allies, but should they be lovers? HBO

"I think as long as Jon and Dany are part of this alliance, things are very simple. They have a common goal, they're in this together with other people," Podeswa said. "But now that there's a special bond between these two, nobody really knows how that's going to play out or what kind of decisions they'll make based on the fact that they're now connected to each other in a much more intimate way."

Looking back at season seven, you can see how Tyrion was often chastised by Daenerys for his failed plans, especially after they lost Dorne and Highgarden as allies. She began turning to Jon Snow for advice more and more frequently.

"So for Tyrion this creates a potential problem," Podeswa said. "Whatever sway he might have had over Dany might not be there anymore, cause Jon may become more important to her than him. The choices she will make may be influenced by this event. So for him the concern going forward is just how is this all going to play out, and what it might foreshadow."
