"Game of Thrones" season 7 Episode 6 spoilers leaked courtesy of a mistake by HBO Spain. As a result, all of the gory details, including three major deaths, have spilled out. If you don't want to know what happens on "GoT" s7 e6 "Death is the Enemy", stop reading now! Two of the big deaths in this episode were humans and the third was a real shocker - one of Daenerys' beloved dragon children was felled, but it wasn't the gold cloaks under Jaime Lannister's command that took down the beast - it was the Night King!

White Walkers more powerful at the end of "GoT" episode 6

"Game of Thrones" spoilers show that Jon Snow, The Hound, and others traipsed into the cold winter beyond the wall to capture a wight to convince Cersei to stop the war, but their plan failed horribly.

The mother of dragons flew in with her three dragons blazing to save their butts and that's when things got even worse. The Night King hurled a spear into the neck of one of the dragons, killing it. That's bad, but then things got unimaginably worse. The Night King turned the dragon into a wight.

Now "GoT" has two dragons of fire and one of ice. By the end of season 7 episode 6, Viserion was the property of the Night King and a formidable ally that just made the battle against the dead so much more challenging. In addition, despite Dany's intervention [VIDEO], Jon was almost gobbled up by wights and it was his uncle Benjen Stark that saved him, only to be overrun by the dead himself even as he got Jon onto a horse and headed back to the safety of the wall.

Benjen turning wight could prove disastrous

"Game of Thrones" spoilers tease that Benjen's intervention to save Jon could create another formidable opponent on the side of the dead. Benjen mentioned in prior seasons that he can't pass through the barrier of the wall because he's got wildling magic keeping him whole. The Children of the Forest saved him from going ice zombie by putting dragon glass in his heart. That could mean either he's impervious to turning into a wight or that he might be a truly terrifying wight if the Night King makes him a blue eyed killer.

It appears that once again, Jon Snow knows nothing. Also dying on this Sunday's "GoT" season 7 episode 6 is Thoros of Myr, the red priest of the lord of light and traveling companion of Beric Dondarrion and, more recently, The Hound.

Thoros got thrashed by a wight polar bear, but the gang at least captured the wight they needed for PR purposes. The other good news is that once Dany rode in to rescue the King of the North, he decided he can bend the knee (a little) since she had his back in the fight against the dead.

Littlefinger stirs the sister pot

Another tidbit from "Game of Thrones" season 7 episode 6 is that Littlefinger set Arya up to read the latter Sansa wrote from King's Landing while under duress after their daddy just lost his head. He tries to drive a wedge between little assassin sister and the acting Queen of the North Sansa. Arya confronts big sister about the letter and then Sansa shuts down Littlefinger when he tries to get her to usurp Jon's power in his absence. When called to the dragon pit, where The Hound has taken the captured wight, Sansa sends Brienne as her representative.

Jaime Lannister is on the way to the dragon pit as well but it remains to be seen in "Game of Thrones" if he goes to check the white walker story or if he plans to try and take down Cersei's enemies now that she's won him over with her latest incestuous pregnancy since all their other children are dead. Of course, Gendry is alive and well since he helped cart off the wight and he's the only true biological child of the last legit king Robert Baratheon. Jon is still clueless that he's a Targaryen of royal blood which is why Dany's dragon sniffed him out and didn't bite.
