The reference to dead things in water is definitely about white walkers and the hardhome shenanigans.

But I do see the sacrifice happening, feels like such a significant plot point and very earned for the story so far. But I wonder who’ll do it. Stannis is all the way near winterfell.

I’m not sure exactly what will happen but watch these 2 locations.

I’d love to …if we had the books 😶‍🌫️
