Whoa, Does the ‘Game of Thrones’ Episode 5 Trailer Hint at the Existence of a Fourth Dragon?!

*Warning: Spoilers ahead*

Get ready, Game of Thrones fans. The great Battle of King's Landing is coming, and we can say that for sure thanks to the newest trailer from HBO.

The streaming service debuted episode five's preview on Sunday after the absolute chaos that was episode four, "The Last of the Starks." But we also got a glimpse of an important character's reaction, and it feels super spoiler-y. Here's why.

The 35-second trailer starts out with a shot of Tyrion in the war room of Dragonstone, seemingly pondering his doubts over Daenerys's claim to the throne. We next see his sister Cersei looking out over King's Landing and smiling, as the sound of a ticking clock begins in the background. Jon, Davos and Tyrion have arrived at the gates of the city with what's left of the Stark-garyen forces…and another big battle is imminent. 

We next see Euron on his ships, with his men setting up more Scorpion crossbow weapons for another dragon attack, then a quick cut of Tyrion in a dark room lit only by candlelight, the Golden Company marching through the streets, and Greyworm who seems ready to exact alllll the revenge for Missandei's death. We cut back to Greyjoy and his men prepping the giant crossbow—but, wait! Euron looks toward the sky for Drogon (Dany's last remaining dragon), and his expression changes from smugness to shock.

But what could be so shocking about seeing Drogon? Euron's already taken down Rhaegal, and knows there's one remaining dragon, right? Could it be that Dany has actually found a fourth dragon? The theory, which gained steam at the beginning of season eight due to the change in the opening credits of the show, says that the Azor Ahai prophecy refers to "waking dragons out of stone." Perhaps Dany or Jon found a fourth dragon egg that was awoken out of stone?

Euron's surprise while looking up at the clouds could also pose a different outcome. What if the Stark/Targaryen forces (or even Gendry) find a way to protect the dragon with armor? Then the Scorpion weapon wouldn't work, and Cersei's army and the Greyjoy fleet would be completely (for lack of a better word) effed.

Emilia Clarke recently spilled the beans about the next episode, which will run 1 hour and 20 minutes long, when she told Jimmy Kimmel that episode five was even more insane than the great, big Battle of Winterfell.

“Episode five is bigger," Clarke said. “Episode five is—I mean, four and five and six, they’re all insane, but like… Find the biggest TV you can.”

Tune into episode five on May 12, 9 p.m. on HBO to see if we're right about the fourth dragon.
