AN: Something not-so-sweet for Christmas
It was Christmas Eve, snow covered each surface painting the world white, smothering every sound and smoothing all edges.
"Cas! Castiel!" There was no worry in the older Winchester's voice but pure panic.
The Angel slowed down so Dean could catch up with him. He did not stop. That was no longer an option.
"Dammit, Cas!"
A warm hand landed on his shoulder, tried to turn him around, but the Angel continued his way unwaveringly.
"Cas, Anna told me..." Dean was now walking next to him, traces of hardly suppressed fear on his face.
Of course Anna had told him. Castiel had expected his former superior to rush to the Winchesters and reported on the Angel's plan. He simply nodded.
"Are you really...?"
Again Castiel affirmed without words.
"Please, Cas, you can't do this. You're not strong enough. You wont...!"
"Dean, we both know Lucifer has to die. And there is no other option."
"You are planning to sacrifice yourself?"
"It is my..."
"No, Cas!" The older Winchester interrupted the Angel passionately. "No! You are not pulling that martyr-stunt again!"
Finally the Angel stopped and fully turned to the hunter.
"Dean, if there was one thing you have taught me, it was to make my own decisions. Although I am no human but a mere Angel I have learned the value of free will. Please do not deprive me of the right to chose my own path. I have made my decision." Slowly but determined the Angel started to walk towards his destination again.
"Cas..." Dean sounded pained. Castiel knew that the hunter had realized he could not longer stop the Angel.
Castiel suddenly came to a halt again and looked at the older Winchester. "I do believe there is a custom to grant a man who is about to die a last wish."
Dean nodded, obviously not trusting his voice.
"I want you to kiss me."
As the hunter's lips touched his own Castiel closed his eyes savouring the feeling. Their first kiss would also be their last. Alpha and Omega. He smiled against Dean's mouth and pulled away. Still with the taste of his hunter on the tongue he turned to face Lucifer. And save mankind.
