Hold on tightly, Game of Thrones fans.

Following a heavily-involved episode this week - "The Ghost of Harrenhal" covered everything from Arya's new pact, to Jon Snow's latest adventure, to Tyrion's intriguing discovery, to Dany's marriage proposal - the action seriously picks up on next Sunday's "The Old Gods and the New."

I've seen the installment, and we're talking beheadings, attempted rapes and one shocking criminal act. It's easily the most suspenseful episode of season two so far.

And it all starts with "news from Winterfell," as teased in the following trailer. Check it out now and get your first look at what's to come:
