"Gabriel you son of a bitch!" Dean yelled vainly.
Cas looked over to Sam, who was still trying to struggle out of his binds. By now the strain of being hung upside down was starting to make the blood rush to both their heads. Sam was in worse condition, being only human. Sam called out to his brother, which brought Dean running. The two tried to unchain him, but there was nothing to break the chains with, and the key to it's lock was missing. Castiel had a similar predicament.
With no keys and two locks, Dean felt rather hopeless, but there was no way in hell Gabriel was going to get what he wanted. Dean was going to fight until the end. After all, he was a Winchester.
When clockwork started turning, and a loud ticking noise boomed through the room, Dean guessed that the game had begun. The floor started moving. A large strip that Dean stood in started to move backward as strips of floor around him crumbled, revealing a large mass of water. It probably contained something terrible right? Cas and Sam dangled helplessly as Dean took in the situation. There was now no floor accept for the strip he'd been standing on. Maybe there was something in the water he needed. The more Dean looked at it, the more he was sure he'd have to dive in eventually.
So, being Dean, he stripped.
Dean stripped down to his pants, sacking his clothes and shoes in a pile behind him. He did however, secure the little knife he kept on himself at all times. Just as he prepared himself to jump, a voice boomed throughout the room. "Slow down there Deano! There's some pretty bad fish in that lake."
Dean growled in disgust.
"There's some sharks, jellyfish, piranhas, Oh! I think there's also an octopus."
"Where's the little mermaid?" Dean sarcastically joked.
"Ha. Ha. Very funny."
"Well what am I looking for? A key? A blowtorch? Harry potter's wand?" Dean didn't like this game, but Gabriel wasn't one for sarcastic humor so it was one way he could get back at him, at least a little bit.
"Look, I can't tell you that, but you'll know it when you see it."
Dean wasn't in the mood to hear anymore from that SOB so he jumped. The water was cool, but not freezing, and his eyes didn't sting when he opened them. There wasn't any salty taste or strange texture. It was some weird water if it could hold sharks, octopus, piranha, jellyfish and whatnot but still have no texture. In another weird twist, Dean could breathe. What the heck? Oh, this was probably Gabriel's slightly twisted sense of humor at play.
The ground was scattered with stray clumps of sand and seaweed grew from them. Seaweed? No, to the touch it was plastic. It was a big fish tank, glass sides and even the little diver that spouted bubbles. Dean saw the sharks before anything else. There were three of them. Three sharks, a school of piranha and the octopus was no doubt in the little cave at the bottom's corner. What about the jelly fish? Dean couldn't see them anywhere. There was a treasure chest smack in the middle. Bingo.
Dean gripped tightly at his little knife and started to swim.
