E/O Challenge: Steady. Happy Birthday WoodBurner!
Sam dove into the water after his brother, who was torpedoing to the bottom of the lake, attached to some sort of chain. The demon that had put him there had since disappeared. He swam hard after Dean, and caught up with him as the heavy chains hit the bottom of the lake. Dean was thrashing against his restraints. Steadying himself on the sand, Sam yanked at the chains, and finally freed his brother of the entangled mess. They surfaced moments later, coughing and sputtering, and climbed back into their rented boat floating in the middle of the lake.
"Dean, the next time you throw something overboard, make sure you aren't attached to it, ok?"
