Castiel's grace showed bright as he dragged himself and Dean out of the barren wasteland that was purgatory. Landing softly on the ground, Castiel released Dean and tried to force his grace back into his vessel. "Cas, are we here, can I open my eyes." Dean hears a loud siren like noise. "Cas, what is going on?" Dean resisted the urge to open his eyes. Castiel's true voice rang out loudly as it was compressed into the small vessel. Dean crumpled to the ground covering his ears. "Cas, are you ok!" Ringing cutting off suddenly, Dean moved around searching for any sign Castiel was ok. "Cas, you ok, can I open my eyes?" Dean heard no response. "Cas, are you there?"
Dean heard nothing. Dean slowly opened his eyes, his gaze fallen on Castiel. Dean moved quickly to Cas' side. "Cas, you ok." Dean shook Castiel's body but no response was given. "Cas, wake up, you ass!" Castiel's body shifted. Dean let out a sigh of relief. "Cas, you scared the crap out of me." Dean moved to help Cas up. "You ok," Castiel's mouth opened to tell Dean he was fine but all that came out was an ear-shatter siren. Castiel tried to speak to get Cas to cover his eyes but no words came out. Castiel stood and moved away from Dean. Dean stared as Castiel's vessel convulsed, something was pushing to get out and it wasn't giving in any time soon.
With the little control he had, Castiel brought his Angel blade into existence. His hands shaking from the power being held back, Castiel threw the night towards Dean. Dean looked at the Angel. "You can't expect me to, Cas no." Castiel moved to speak but still nothing emerged but a screech. Dean quickly made a grab for the Angel Blade and advance towards Castiel. "I'm sorry, Cas." Castiel turned towards Dean, his lips moving again but no sound was heard. "I know Cas, I love you too." Dean plunged the blade into Castiel's heart cutting off the rest of the sentence. Castiel's eyes shined a glorious white and finally faded as the body feel to the ground motionless.
