Castiel waited until Dean had bandaged himself up again and undressed so he could sleep before he made a move. He flew away, his wings trembling with excitement as he soared. He touched down within that same cement building he'd been a prisoner in only previously. Cas tended to his injued brother. He used his grace to stop the large amount of bleeding, and healed a lot of the smaller scars, as well as his brother's punctured nose. Once Gabriel's eye was mended, the two started to talk.

"How do we heal Sam?" Castiel asked.

Gabriel shot his brother a concerned and questioning look, "Heal him?"

For a few moments, the two were just staring at each other in an awkward silence. Castiel wasn't asking a question, he was stating, "You didn't know."

"Didn't know what?!"

Castiel looked down at the floor, he didn't want to be the one to tell his brother, "I can't wake up Sam."

"Wait, what?!" Gabriel took a step closer, cocking his head to the side and squinting his eyes in confusion.

"He's been unconscious since our encounter. Dean blames you but I know you-"

"I would never do that to Sam!" Gabriel yelled, outraged.

Castiel raised his hands defensively, "I understand but is there any way that you've messed up and-"

"No!" Gabriel screamed, "I used my... my grace to make him sleep. He should just wake up!"

Castiel noticed the water straining Gabriel's eyes. He looked like he was about to cry. "Is there anyway that something else happened?"

"I wouldn't hurt Sam. I really do love him..." Gabriel's voice hitched as he trailed off. "Why'd I have to fall in love with a human? A Winchester even."

"It's not hard to fall for a Winchester."

Gabriel lifted his head. "That's right. You've got the hots for Deano. You know," Gabriel was so close now, his breath heated Castiel's face, "My test was supposed to take Dean out of the picture. Sam's so loyal to his brother. Angels were born possessive and protective, and I don't want to share him! I want that Winchester dead!"

That set off a red flag in Castiel's head. "You're not going to kill Dean Winchester."

"Oh I'm not?" Gabriel took a few steps back, the lights cracking to reveal his large wings a few times, their shade darker then a holy angel's ought to be. "I'll help Sam get better by myself. Don't get in my way Cassie."

"Gabriel you're-"

"Oh my wings?" Gabriel smirked, "Didn't you know?"

Castiel frowned with anger and confusion as Gabriel pulled out an angel blade. He drew his own with regret, "What's going on Gabriel?"

"You honestly didn't figure it out?"

Castiel gulped as the words ghosted out from Gabriel's mouth, "The grace of light is for wimps." His mouth was crooked and menacing.

Then the battle began.
