5 important things you probably missed on the 'Game of Thrones' season finale

Warning: spoilers ahead for Sunday's episode of "Game of Thrones," "The Winds of Winter."

Three houses have risen from the ashes and a huge Jon Snow revelation rocked the season-six finale of "Game of Thrones" this week.

Cersei Lannister (Lena Headey) opted for a scorched-earth policy instead of going to trial in front of the Faith Militant. That decision would wipe out all her enemies and give her the Iron Throne, but it also led to the death of her final living child.

Meanwhile, Daenerys (Emilia Clarke) assembled her forces and locked down enough ships to begin her return to Westeros. Along the way, she solidified her unlikely alliance with Tyrion Lannister (Peter Dinklage), but has resolved to take on a new alliance via marriage.

And over at Winterfell, Jon Snow (Kit Harington) and Sansa Stark (Sophie Turner) tried to patch up any issues of trust between them after she hid the inclusion of Littlefinger (Petyr Baelish) and the Knights of Vale in the Battle of the Bastards.

But their sister, Arya (Maisie Williams), is on her own mission of vengeance.
