"Ramsay gets a gift."
As the episode promo reveals, a gift is set to be delivered to newly self-appointed Ramsay Bolton, Lord of Winterfell. What do you give the man who has everything as a result of sudden patricide? Short of his runaway wife and favorite toy (Sansa and Theon, respectively), you might want to give him something that will further help him secure the North.
Speaking of which, wasn't there another Stark who escaped his clutches and was last seen in season two high-tailing it to the Last Hearth, the seat of House Umber, to be sheltered secretly by Stark bannermen? Sansa is currently running as fast as she can away from Winterfell, and Jon Snow is still chilling at Castle Black -- but if there's one thing that could entice one or both of them to their old home, it's news that their young sibling, who had been presumed dead, had fallen into Ramsay's clutches.
That, or the news that Ramsay had smiled the way he's smiling in the screengrab above. What Stark wouldn't risk his or her life to smack that grin off his face?
