The Four

[ahabmyth]

So as the three attempt to reach the tent and the two by the Cedar try to keep warm by the dying embers, the four are looking for fuel, they are in hearing range of the Cedar two ,tragically Lyuda falls through a cornice and lands on rocks Brignolle manages to grab her arms and attempts to pull her from the icy water Lyuda hangs onto the rocks while Brignolle finds a place to wade into the water but falls into the creek trying to save her. Seeing the two friends in trouble the other two rush over to help, Brignolle appears to be unconscious .The two walk down into the freezing water and try dragging Brignolle out but they too succumb to the cold and freezing water. Acting like a dam all three are slowly washed together in a deadly embrace.

Yes you can clearly see that the two under the cedar tree with their fire not having enough fuel to sustain them, decided to quickly dig this den laying down branches and clothes from the dead. Who might not have been fully dead and so donated their excess clothes to the dens carpet.
