A/N: Soooo. I recently rediscovered my love for Balthstiel so have some! Its very pain. Yup. Prompt 30: Death

Regret is the worst posion

"Well, you've always got little old me…"

"Yes. I've always got you."

"Cas…"

He was dead. Gone, deceased, kicked the bucket, pushing up daisies, dead. Castiel looked at the blood stained blade in his hands and wept. Crowley appeared beside him and scowled.

"Oi, angel. You ready to do this?" Castiel raised a hand and banished Crowley from the room, before disappearing. The young angel was running, from himself, from what he had done to the only person who had ever truly cared and wanted him but he didn't know where to run. He wanted Balthazar, he wanted his best friend but he had just killed him. So he kept running, as far as he could.

Balthazar, oh Balthazar, I'm so sorry, I never… I shouldn't have… you were just trying to protect me as always, I'm so sorry.

Castiel stopped in Sibera, sitting down and sobbing.

I should have listened. I should have paid attention. Oh, Father, what have I done? I killed him, Father, my best friend, my loyalist companion. My Balthy. Father, help me. What do I do? How do I go on?

He felt like he was being torn to shreds. He felt like the Grace was draining from him. But all Castiel wanted to feel was nothing.

My darling Balthazar, why did I do it? I love you, Balthazar. I love you. I'm so very sorry.

Then another voice, thick British accent through the tears.

I'm sorry too, Castiel. I love you, Father knows, I love you so much and I'm so sorry

And Castiel smiled.
