The Man In Black wakes up near the well to find that in has been filled in and partially destroyed. He is already upset when he turns and sees black smoke billowing up in the distance. He runs towards it and arrives at his people's village to discover that everyone is dead and the homes are burned.
He walks through the remains and finds his Senet game. He grasps it and holds it towards is head as we see pure rage coursing through him.
The big question is, how did Mother manage to kill all of these people and destroy the village a well without some kind of power or ability like the smoke monster has? It seems impossible that she, as a human could have caused this destruction, so how was it achieved? We may never know.
