Westeros is becoming one big meet-up.

A new trailer for "Game of Thrones" Season 7, Episode 2, "Stormborn," teases some major, long-anticipated encounters between various characters. The video was leaked ahead of the show's panel this afternoon at San Diego Comic-Con.

"Stormborn" continues the threads spun in the premiere, with Daenerys Targaryen asserting her birthright to rule the Seven Kingdoms. Meanwhile, Cersei Lannister ( declares to Randyll and Dickon Tarly (Sam's family) that "the Mad King's daughter will destroy the realm."

Up North, Jon Snow has clearly heard of Daenerys' arrival at Dragonstone and wants to ally with her and her dragons against the White Walkers.

There are glimpses of children practicing archery, Lord Royce warning that a Targaryen can't be trusted, and more insidious whisperings from Littlefinger to Sansa.

And it seems Daenerys' "unexpected guest" (as teased in the synopsis) is Melisandre, who turns up at Dragonstone. "I believe you have a role to play," she says, adding, "as does another."

Does this meant Aunt Dany and nephew Jon will soon meet?

"Game of Thrones" airs Sundays at 9 p.m. on HBO.
