River blinked for a moment as Grim panted next to her. She was lying on a lawn. There was a streetlight flickering and a house.
"I know where I am." She scrambled to her feet. Through the window was the same family. They were safe for now. But River saw Sam-no. She understood somehow the controlling mind was the Fire, not the Giant. The Devil was wearing Sam as he walked down the sidewalk, toward the house.
"No!"
River threw herself at him. She was on his back and holding on, pounding on his chest.
"Sam! I know you're listening! I know you can hear! Fight the Fire!" She was screeching like a Banshee. The element of surprise was her friend. The Devil was confused and trying to pull her down. The family inside had heard the fuss. The man-she heard the name 'Dean' clear as day-told Lisa to go out the back with Ben.
In a moment Dean had emerged and his eyes were wide. Satan threw down River and she yelped.
"Grim!" She cried out, "Help!" The smoke charged. Satan glowered before vanishing. River collapsed on the grass, panting.
"What are you?" Dean stood over her and River sighed.
"I wish I knew."
