Winter isn’t coming, it’s here! Earlier this week, the latest trailer for Game of Thrones seventh season hit us like a wildfire explosion as it teased some of the most anticipated events of the series. There’s a lot to unpack here, including one of the wilder GoT theories that emerged last fall. Today’s Nerdist News is tearing down the Wall to bring you the details!

There are potentially major spoilers ahead for Game of Thrones season 7. And we mean it. Major. Spoilers. If you wish to remain Unsullied, then it’s time to turn back!

Join host and Hand of the Queen, Jessica Chobot, as she walks us through last year’s plot leak which indicated that Sandor “The Hound” Clegane and Beric Dondarrion would undertake a mission north of the Wall to do capture a White Walker and bring it to King’s Landing. Their theory is that not even the Mad Queen Cersei can turn a blind eye to the White Walkers when she sees one in the flesh…so to speak. But we would have to ask: have they met Cersei? She would still find a way to avoid dealing with that conflict.

The newly released trailer features footage that backs up that theory, as both Dondarrion and the Hound are seen in the snow before we catch a glimpse of the Hound’s homecoming to King’s Landing. You may recall that the Hound didn’t leave the city under the best of terms, since he essentially abandoned Joffrey during Stannis Baratheon’s siege of the city. And he didn’t mince words about it!

There’s no way that Cersei would let that slide, and that may inspire her to unleash her pet monster, Gregor “The Mountain” Clegane on the Hound. That’s right, the Cleganebowl may finally be happening this season! But which brother will make it out of that battle alive?

Are you excited about the Hound’s potential rematch with the Mountain? Let’s discuss in the comment section below!
