This week's episode of Game of Thrones ended with a bloody and fiery battle in the sea. Although, there was plenty of fun stuff that happened before the battle, like Grey Worm and Missandei finally getting it on!
The Red Woman returned to Dragonstone, sans Stannis, and told the Mother of Dragons to meet with the King of the North. When Jon Snow got the invite from Daenerys, he agreed to the meeting. Jon then left Sansa to be the Queen of the North while he is gone, and made sure Littlefinger doesn't try to become her King. Jon choke-slammed Littlefinger up against a wall and told him, "Touch my sister, and I'll kill you myself."
Elsewhere in Westeros -- Cersei got herself a sweet dragon-slaying crossbow. Arya's direwolf found the young Stark girl, and was still pretty butthurt about Arya throwing a rock at her, so she bounced with the rest of her wolfpack. And Sam was giving Jorah some serious microdermabrasion, cutting off the greyscale.
Tyrian set a plan into motion where Yara and Theon Greyjoy were to sail to Dorne with Ellaria Sand and her Sand Snakes to get the Dornish army and head to King's Landing. Unfortunately, just when Yara and Ellaria were getting to know each other better, Euron Greyjoy crashed the party. He slammed his ship into their ship, and came aboard swinging his giant axe. He killed two of the three Sand Snakes, and took Ellaria and her daughter to be his "priceless gift" to Cersei. Last week, Euron promised Cersei a priceless gift. And what do you get the woman who has everything? You find the person who killed her daughter. Now that's romantic!
Euron also had a small family squabble with Yara, that ended with Theon getting a chance for redemption. But the sight of the violence made Theon turn back into Reek and he jumped overboard, leaving his sister stranded with their crazy Uncle Euron.
