A single line of cut dialogue from the Game of Thrones Season 8 premiere offers further evidence of Jon Snow’s intimate connection with the dragon Rhaegal — one that could radically change how we perceive dragons and their connection to the Targaryens.

During the final version of the episode that aired on HBO, after Daenerys Targaryen and Jon Snow go on an intimate dragon ride, Jon says, “You’ve completely ruined horses for me.” After a long pause, Daenerys says, “We could stay a thousand years” (likely another bad omen referencing Jon’s last serious relationship).

But in an 18-minute behind-the-scenes video released on the official Game of Thrones YouTube channel on Monday, we get an additional line of dialogue from Jon Snow as part of a funny little blooper.

“You’ve completely ruined horses for me,” Jon says. “It almost seemed like he knew where I wanted to go.” Then actor Kit Harington slips on the ice and snow and curses.

This single line of cut dialogue explains how Dany is able to control the dragons, and it should also be a huge sign to both her and Jon that he’s also a Targaryen. Dragons forge an intimate psychic connection to Targaryens, and they’re able to respond to the will of the humans they’re bonded to.

“Only Targaryens can ride dragons, and that should be a sign for Jon,” series co-creator David Benioff says in the post-Episode 1 mini-doc. “It’s a major thing for her when she sees they have some kind of connection to him. They allow him to be around them.”

Now that the dragons have forged this connection with Jon, he can presumably ride either of the dragons whenever he wants.

“Seeing Jon and Dany on the dragons together — it’s a Jon and Dany moment,” the other co-creator D.B. Weiss said, “but it also seeds in the idea that these creatures will accept Jon Snow as one of their riders.”

Weiss’ comment here additionally implies that Jon doesn’t just have an exclusive connection to Rhaegal, either, whom we’ve theorized is the reincarnation of his father. Jon might even one day ride Drogon.

We have no idea how the rest of Game of Thrones Season 8 could play out, but if Daenerys is killed somehow, then it sure sounds like Jon Snow could become the Father of Dragons and gain control over them.

Game of Thrones Season 8 continues Sundays on HBO at 9 p.m. Eastern.
