Along with yesterday's Game of Thrones."

The clip begins with Daenerys Targaryen describing the major families of Westeros (Lannister, Stark, etc.) as spokes in a wheel -- a wheel she intends to smash. Does this mean Khaleesi is ready to fight for the throne?

There's a ton of new footage: Tyrion glimpses one of Khaleesi's dragons; Jon Snow urges cooperation with the wildlings, even as they continue to battle; Arya and Sansa, on different sides of the ocean, look fearful; and fights ... lots of fights.

"Game of Thrones" season 5 premieres April 12.
