Dean stood up, the water going up to his knees and rising. He looked up at the security camera in the otherwise blank room. The only other thing was a bookshelf and a radio that sat on top of it to avoid the rising, freezing water.
"WHO ARE YOU?" He yelled at the camera. He pounded his fists against the metal walls, trying to find a way out, but all he saw was the trapdoor on the ceiling that he couldn't open. Sam was sleeping, up his chest in water, still knocked out from the gas. "WHAT DID YOU DO TO OUR FRIENDS?"
"Your friends?" A voice came through the radio. Dean turned to it angrily. "Your friends? The other three? Oh, they're in a car somewhere. A car that's rigged to explode."
"What?"
"Yes. They have thirty minutes if you manage to get out of here, before it explodes. You have to find the car keys, and rescue them before that time is up and the car goes boom. And no cheating, Winchesters. If you try to get into the car any other way than the keys, say goodbye to your friends. And you also might think: Well, at least two of them will survive an explosion, but they really won't if the bomb has angel blade shrapnel, made by yours truly. And- why don't we just stay in this room? You're either going to die of hypothermia or drown, or both, and I'll just kill your friends anyways. "
"Why are you doing this?"
"Why? Because it's like an art trade. Lucifer is killing the Doctor, I'm killing you, and the Daleks are handling Sherlock and Watson. I can't wait to see the looks on their families faces, sad Molly and poor little Rosie when they realize that I'm responsible. Oh, and the looks on your family's face when they realize you're dead, if that's the case. And once I tell them you're dead, I'll kill the little one first, then the blonde, then the angel last so I can enjoy it the most. I mean, come on, how many angels does anyone get to kill?"
"You'd really want to miss Sherlock's last words?" Dean asked. "The light leaving his eyes? Maybe you shouldn't let someone else kill him."
"The result is the same. Plus, I enjoy blowing people up, so…anyways, if you need me, my name is Moriarty and I'll be here until you die."
Moriarty hung up, the radio going silent. Dean yelled, kicking the wall. How the hell did this happen?
