Only You

Demons

As they pulled up in front of Crowley's mansion, the group huddled together for one last good luck, before they grabbed their stuff from the boot of the Impala. John handed Dean a pair of sunglasses.

"Dad, it's pitch black in there. Why do I need sunglasses?" John smiled.

"These sunglasses have been burned with Holy Fire. When you wear them, you'll be able to see the angels wings and a demons true face, just so if you meet one, you don't mix them up with a human and accidentally stab them, as you do."

Dean actually didn't do, but he put them on anyway. He looked around at the Novaks. He gasped. Their wings were huge, and beautiful, though Dean thought Cas' were better.

They scoped the place out, but they didn't see anyone or anything. Just to be safe, they found the back door, and entered silently through it. They cleared the first floor without finding anything, no sign of Castiel. They climbed the stairs and checked every single room, but there was still no signs of life, or the angel.

Then they decided that because Dean and Lucifer were the smallest, they could go check out the attic. Dean and Lucifer pulled their torches out, Lucifer with a gun, and Dean with a knife that had funny runes etched into it. Dean tiptoed around all the junk that Crowley had just dumped up there, when he heard a creak from behind the bookcase that was less than 6 feet away from them. Lucifer and Dean shared a look, before Dean silently stepped to the left side, while Lucifer stepped to the right. They jumped around the sides of the bookcase at the same time, Dean slammed the demon into the wall.

"Where's the angel?!" He growled, but the demon only laughed, as Lucifer pulled Dean off it. "Lucifer, what are you doing?" He smirked.

"Well, well, well. I couldn't let you find my baby brother that easily, could I?" Dean frowned at Lucifer,

"What do you mean? Lucifer, tell me what's going on!" Lucifer was grinning now, but he didn't say anything. Then it dawned on Dean. Everything did.

"It was you, wasn't it. You worked with Meg to get him that day. She's just one small demon, he could've smited her without hesitating, not that he would, he's too nice, but he could've gotten away. She would've needed help from something much more powerful than him. You. But you wanted something, didn't you? He'd been 'off' all day. Something was wrong with him. So what was it?" Lucifer grinned wider,

"So, the penny finally drops! I was wondering when you'd figure it out. Yes, we teamed up, yes, we attacked him, no, I don't care, no, I wont tell you what I wanted."

"What do you want from me?!"

"It's really quite simple, Dean-o. You let this demon possess you, or Castiel and your ickle, wittle, baby brother both die." Dean stared at him.

"You wouldn't. Cas is your brother." Lucifer leaned forwards.

"Wanna bet?" For some reason, Dean believed he would actually do it.

"Why? Why would you do that?" Dean whispered. Lucifer just laughed,

"I have my reasons, none of which you need to know. Will you do it? Or do your brother and your crush have to die?" at that very second, Dean couldn't care less if people had figured it out. He knew exactly what his answer would be. He wouldn't let them die.

"Angels can see if people are being possessed, can't they?" Lucifer nodded, "So your family would notice if I was possessed when we get back to them, wouldn't they?" Lucifer's brow furrowed.

"Actually, yes, they would. I didn't think about that. Maybe I'll just kill them any-" Dean quickly reassured him, in case he just decided to kill the two most important people in his life,

"No, no. It's okay! I'll just have to say yes after we rescue Cas. Will... will you, you know, let me say goodbye to my brother? And Cas?" He hated the way his voice cracked, but he needed to ask this.

"You can say goodbye to Cas, but your little brother... I don't think so." Lucifer drawled with a shit-eating smirk on his face. Dean felt his heart shatter, but he couldn't do anything about it.

"Deal." Lucifer smiled.

"Good. You have my word that your brother will be safe." Dean just glared back. Lucifer turned back to the demon, "Come to the basement. Stay hidden, and after our little friend here has said goodbye to his boyfriend you get him, yeah?" The demon smirked.

"Yeah." It vanished. Lucifer turned to Dean,

"Shall we?" Dean nodded, defeated. They climbed back down from the attic and met up the the rest of the Novak family.

"Are you two okay? You were up there for quite a while," John noted.

"We-we're fine, dad." Dean practically whispered.

"Okay then, there's only one other place to look. Bring your spare knickers, girls. We're going down to the basement."
