Castiel didn't know how long had passed between Lucifer's belittling of him and when he thought he heard his name. He was floating somewhere between a peaceful blackness and consciousness that was usually fed at the sound of a gunshot or a faint, far off scream of a soul he couldn't save.
He groaned, shaking his head a little bit and opening up those bright eyes of his, immediately seeing Jo's figure. Castiel had always really liked Jo; she had a fire in her, a spice to life that Castiel found fascinating. She'd even given him free whiskey on many occasions which he appreciated; he found he quite liked the taste of it.
"Jo? Jo... I'm so sorry." he murmured, trying to shake himself of this drowsiness caused by Lucifer's massive and overpowering presence on his body.
"I'm sorry you aren't in heaven anymore... and the angelic war... God..." he rambled, seemingly nonsensical for a moment before he hit a point of clarity.
"Dean." he whispered his name, and a small smile came to his lips. "I... I can feel him. He's close, Jo. Can you guide him to me? Maybe you two can get me out of these chains. I've been here for days."
