Dean clawed at the top of the platform, anxious to be freed from the water. Castiel smiled proudly when Dean emerged, but quickly gestured to Sam, who, because of human genetics, had fainted due to the amount of blood to his head. "Sam!" Dean called out.
"He's okay Dean, just unconscious." Cas assured him, "There's a lot of strain on his brain."
"What about you?"
"I'm an angel. Our genetics don't work that same way human's do."
Desperate, Dean ripped open the little pouch, trying not to look over at his brother, or Cas.
A key! Finally. Now there was just the problem of getting over to Sammy... The platform didn't reach that far, and he couldn't get to him in the water, he was too high. Gabirel chose a perfect time to send his voice through. "Well, nicely done Deano. To be honest, I had my money on those sharks."
"Yeah well, I guess you need to learn a little more about gambling." Dean barked.
"Well, I guess you've already found the next challenge. That key will unlock the chains."
"Great all I need to know." Dean rolled his eyes before stalking over to the edge of the platform, his toes almost over the edge. He tried to reach out, but the jellyfish sting still lingered violently on his arm. The shock split up his arm, causing Dean to grind his teeth.
"Dean," Cas smiled sadly, "It's not going to work."
"It has to!" Dean squirmed, trying to reach out, "This key will unlock you guys. Then you can zap us out of here. We can go home."
"Dean-"
"Slow down there Dean." Gabriel's voice echoed against the concrete walls. "I probably should've mentioned earlier..."
"What?!"
"That key..."
Dean was growing impatient. Enough games. "What about it!?"
Gabriel chuckled, "Well, you get to choose of course, but that key will only unlock one."
