Sunday night’s ‘Game of Thrones’ marked the halfway point of season 3, but the action hasn’t stopped to catch its breath. In anticipation of next week’s episode, HBO has released a teaser for next Sunday’s episode, straightforwardly titled ‘The Climb.’

Acrophobics may want to simply tune into our recaps, because this episode seems poised to terrify even the sturdiest of us with vertigo-inducing shots, as the Wildlings climb the Wall in anticipation of an attack on the Night’s Watch.

The preview also lets us in on some characters whose stories we don’t get to visit every week, including Theon’s ongoing misfortunes and a troubled road ahead for the Little Lords Bran and Rickon, as evidenced by quick cuts away to the horrified faces of their companions Osha and Jojen Reed. But the main storylines of the season are sure to continue going strong in Robb’s newfound plan to get aid from the Freys, as well as the ongoing adventures of Brienne and Jaime, which is a spinoff I don’t doubt many fans would totally tune in to.

Whose storyline are you most invested in this season? Which ones do you use as commercial breaks to freshen your honey wine? Sound off in the comments below, and be sure to tune in to ‘Game of Thrones: The Climb’ this Sunday on HBO.
