Author's Notes: As promised, here is the beginning of the rewrite of the What Happens in Vegas Series. Albeit going down a much different road and with a much different premise. I was going to wait until more was written but I didn't want to be a jerkwad and promise to post and not post! Haha.
Author's Notes 2: I just got done reading the terribly fun "A Real Kind of Something" by Angellia and the Prologue idea is inspired by hers. It's also there so you know there's more to this story than smut. :P
Timeline: Four years post S7 of Buffy and early S2 of Supernatural.
Feedback: Always appreciated! :)

Summary: Marriage, curses, demons, oh my! Buffy and Dean wake up together in Las Vegas with more than a few problems on their plate. (Rewrite of What Happens in Vegas Series.)

Prologue

"Sam, no!"

"Think of the power... coursing through her veins..." the voice hissed in his ear. "Think of what you could be capable of, Sammy!"

He blinked rapidly against the words, feeling them slip around his neck and through his body like silk. It was speaking to him... calling him... enticing him.

"Think of the people you could save, the good you could do..."

And all he saw was Her.

"Yes, listen to her blood, my boy... It calls to you, doesn't it? It wants you to take it. It wants you to kill her. The demon within the Slayer - the original Slayer..."

All he felt was her heartbeat, flowing through the air to him - the power that was held within that one body. He wanted to fight it, knew he should fight it, but it felt so good, so right...

And the thought of her heart beating in his hand was...

Salivating.

His hand clenched the empty air as he raised it. The air around them got colder within the tiny church, the energy coming from all four within its walls enough to crush the stone that held it together. He could see the two standing before him, fighting to get free, to get the other free... he heard his brother saying something, his hands around her, but suddenly none of it mattered.

Nothing but her.

"Dean, get out of here!" he heard her scream faintly but it barely pierced his thoughts.

"No! Sam, stop it!"

"Yes, Sam, by all means..." the voice whispered, a jovial lilt to it. "Do stop this madness..."

"Sammy!"

"You know if they stay together, he will die, don't you, Sammy? She will kill him... that power inside her, only you can harness it, only you can stop her..."

"Dean, go!" She shoved his brother out of the way and suddenly he snapped. With barely a tug inside his mind, he twisted his hand in the air and she was flying through it and into a wall. He heard something crack inside her as she collided with the harsh stone and his brother screaming in the background but all he saw was red. Blood, everywhere... his blood if he didn't act.

"Do it..."

"Dean!"

Suddenly he was in front of her and he snarled, the heat inside his mind getting red hot as he focused on her chest. She fought to move against him, fought to fight him, but his mind's hold on her was too strong as he once again lifted his hand, his fist shaking before moving to force it through her chest. For her heart. For his brother. To save the world from her evil.

Only it wasn't her chest he hit.

Too fast for anyone to see, he was there, in front of him, shielding her and his arm shoved through his chest plate with too much force, his fingers spreading of their own will inside him as blood erupted from the new hole, flowing down, staining his skin. He could feel his heart, feel his bones, feel his lungs as Dean's body collapsed against Buffy's where she hung on the wall. He could see her mouth open, imagine her screams as she fought to save his brother but he heard none of it.

Dean looked into his eyes, his black, soulless eyes, a trickle of blood falling from his mouth as he whispered, his voice laced with pain, betrayal, guilt... "Sammy."

And then he fell.
