Game of Thrones actor Liam Cunningham (Davos Seaworth) teases Sunday’s Game of Thrones episode “The Rains of Castamere” in a new interview.

The ninth episodes of Game of Thrones season 1 and 2 are without a doubt the most memorable in the series so far.

Season 1’s “Baelor” saw the execution of Ned Stark, while last year’s “Blackwater” featured the epic battle of Blackwater Bay.

This Sunday it’s time for Game of Thrones season 3’s ninth episode, “The Rains of Castamere.”

In an interview with Access Hollywood, Liam Cunningham adds to our anticipation for the episode.

“Listen, I’ve been here before, I’ve promised you extraordinary,” he says. “But I have to say, episode 9 of this show will blow the top of your head off.”

He continues, “It’s extraordinary what’s going to happen. […] When we got further on in this series, I am not kidding you, I was opening up these pages, and I’m going, ‘OMG!’”

Watch the interview with Access Hollywood below:

We love that Cunningham’s instant reaction to the events of “The Rains of Castamere” is “OMG.” We’re sure most people will react the same way – or maybe it’ll be more like, “OMG WTF LOL JK NO WAY BRB FEELZ.” You’ll have to let us know on Sunday.

Game of Thrones season 3, episode 9 “The Rains of Castamere” airs Sunday night at 9/8c on HBO.
