Sam, no Lucifer, stood up. You could tell it wasn't Sam just by the way be was standing. "Sam?"

"Sammy's not here at the moment, please try again later." Lucifer said with a smirk.

"Get out of him you son of a bitch" Lucifer showed mock hurt.

"It's not nice to call people names! But I don't think you understand completely what has happened. I got out of the cage! YOU let me out when that naive little angel over there let my beautiful vessel free!" He pointed over to the angel stuck to a wall by Lucifer's power. Lucifer was only a couple of inches away from Dean, which made him nervous.

"Wait you're Lucifer?" Hermione said stepping out of the crowd. Everyone looked frightened, terrified even.

"Ten points to Griffindor! Well done!" Lucifer walked away from Dean and over to Hermione who on instinct took a step away, as did everyone else, "I see you've heard of me then, always nice to make an impression. But you little brother! I thought you would know I got out."

Lucifer pranced up to the other angel and crossed his arms, "Or did you know and just didn't find any reason to tell them?" smirking at the prospect of a breakup.

"Cas... Did you know?" Dean said, slowly, as if he didn't quite comprehend what he just heard.

"No! Of course not!" the angel replied.

"Cas, this is a hell of a lot like when we were talking about Crowley, you know when you lied to me!?" Dean said, scared that not only had he lost his brother, but he would lose his friend because he was really helping Lucifer do whatever the hell he was doing.

Dumbledore was still trying to comprehend who was in front of him. "What do you want?" Dumbledore said, speaking for the first time since this whole fiasco started.

"Why don't you ask Dean? He's the one who is stopping me from leaving!" Lucifer said turning to look at a surprised Dean.

"What?" Dean said, still not understanding what the fallen angel was talking about.

"If you just said yes to Michael I wouldn't have to be here asking you! Would I?"

"And why would I say yes? Hm? Because you asked nicely?" Dean took a cautious step forward.

"What about if I said please?" Lucifer smiled as he said so.

"We stopped you once, what makes you think it won't happen again?"

"Because something has changed between you and a certain angel!" Lucifer smirked at Dean's confusion, he turned around to see the same confused look on Castiel's, "Seriously? Nothing? You guys! The angel who rebelled against heaven for his hunter. Ahhh young love!" Lucifer held a hand over his heart and smirking at the look on Castiel and Dean's faces.

"I-I... What does that- I mean if it was even the case- have to do with stopping you?"

"Because you would care if I did this!" Lucifer clicked his fingers and Castiel fell to the floor, clearly in pain as blood came out of his eyes.

"Dean..." Dean ran over to the angel.

"What have you done to him you son of a bitch!?" Dean yelled at the angel possessing his brother.

"I'll leave you to find that out, in the mean time, I will go and get comfortable in my new suit." Before Dean could do anything, Lucifer disappeared, leaving a crowd of confused students, a angry and worried Dean and an angel who was still in pain.

There was silence, so quiet that you could hear the drops of blood hitting the floor.

"Cas, can you hear me?" Dean said, he pulled Castiel's face up so the hunter could get a better look at what the problem was, "What did he do to you?"

"I'm- I'm human..." Castiel said, slowly and quietly, almost a whisper.

"How? I-I'm sorry Cas..." Castiel sat up.

"It's not your fault..."

"What do you mean you're human? You're an angel!" Hermione said moving towards the hunter and ex-angel.

"Not any more..." Castiel said quietly, looking down at his bloody hands.

"Cas... Did you know about Lucifer?" Dean said, slowly as he didn't want to push too much.

"I- uh, I mean there were signs, but I ignored them, as did the other angels. We all knew- thought he was still in the pit..." Dean sighed.

"So what do we do now?" Dean asked Cas, looking around at the students.

"How did you defeat Lucifer last time?" Harry asked.

"Um... Sam was possessed by Lucifer and jumped into the pit, and stayed there, well until Cas got him out." Dean was confused by all of the shocked faces he was receiving, "What?"

"He's been to hell? Have you been to hell?" Draco Malfoy was stood in the crowd looking terrified.

"Oh.. Yeah, forgot to mention that... Cas? You OK?" Dean noticed how pale Cas was looking and put his hands on the ex-angel's arms to support him.

"I believe that this is what you call blood loss? This was never a problem for me until now I suppose..."

"Oh... Uh have your eyes stopped bleeding?" Dean started to clear off some of the blood from the former angel's eyes. However before the hunter could finish the angel collapsed, "Cas? Cas can you hear me? Can someone help me get him to a bed or something?"
