It's here! Finally, mock exams are over and I can write more :)

"I'm sorry, Cas." Bobby said. Cas turned away from him and walked out of the room.

They walked back to Balthazar, who had crossed his arms across his chest, and was tapping his foot.

"Are you going to let me go now?"

"No." said Cas. "We need any information you have. Anywhere Zachariah's been that he might be again."

"Do you think he's stupid? He won't hide anywhere twice. Although, he does quite like abandoned warehouses." Balthazar didn't have to say anything else. Cas was out of the room before you could say 'Chuck'. Bobby chased after him.

"And how exactly am I supposed to leave now?" shouted Balthazar.

"Figure it out." yelled Bobby, running out of the room.

Cas was stood in the living room, one arm resting on the mantle.

"Cas." Bobby said. "We will find them, don't worry-"

"Worry?" Cas burst. "How can I not worry? These are my friends, my only two friends in the world. I don't know where they are or what's happened to them, and you expect me to not worry?! They could be in any abandoned warehouse in all of America. I can't not worry." Bobby tried to remain calm.

"Yes. We have to."

"I can't stay calm. I can't. They could be dead!"

"Crowley..."

Cas looked at Bobby in confusion.

"What does Crowley have to do with this?"

"He can help."

"We've already tried. He can't help."

"Not him- the demons."

"What?"

Within a few minutes, Balthazar had been freed and a devil's trap had been painted on the floor. When Crowley appeared, he was, well, furious.

"Do I look like a manservant?"

"No."

"Then stop calling me!"

Bobby emerged from behind the door and Crowley fell silent.

"We need your help." Bobby said.

"Yes. I know. Sam and Dean. You've already asked. I hate to break it to you darling, but you're losing your memory already."

"Idjit." Said Bobby, but he couldn't help smiling. "We know you've already given us absolutely no help, but now we need your demons."

"I beg your pardon?"

"We need your demons. To find Sam and Dean."

"I'm sorry, I'm not quite following. Why do you need my demons?"

"There's only two of us, but there are thousands of demons. If we use your demons then we can find them faster." said Bobby.

"And why should I help you find them?"

Bobby opened his mouth, but Castiel got there first.

"Because boyfriend's boyfriends."

"What?" said Crowley.

"Ignore him." Said Bobby. "Just help us. Please?" He tried his best to force a smile. Crowley raised an eyebrow.

"Fine. Let me out of this damn devil's trap so I can assemble the force, as such." Cas moved forward and scrubbed one of the lines with his foot.

"Thankyou." Crowley said, before disappearing. He reappeared only a few minutes later.

"The force is assembled."

"Dean would have made an Avengers reference here." said Cas. He looked sad, and just sort of stared at the floor. Bobby patted his shoulder.

Crowley was just starting to walk towards Bobby when a demon appeared.

"We found them."

Cas immediately spun around to see a man, around 6ft tall, with brown hair in a kind of bedhead style. It suited him. His eyes were a deep hazel colour.

"Where?" Cas asked.

"What's it to you?" asked the demon.

"Where are they?" Crowley asked, stepping forwards.

"A warehouse in Wyoming. 221b Baker Street." The demon disappeared, and Crowley turned to Bobby.

"There you go. 221b Baker Street." Bobby walked over to Crowley and pulled him in for a hug. Crowley kissed his forehead, but before things could go any further, Cas interrupted.

"We have to go. Zachariah will know that his location has been revealed. He will move soon." Bobby looked sympathetically at Crowley.

"Toodles." said Crowley, and disappeared.

Cas and Bobby stood facing the intimidating exterior of 221b Baker Street, Wyoming. It was dark grey, and made of ridged metal. It was really just a typical warehouse, but the fact that they knew what awaited inside made it chilling.

"We have to move." said Cas. He was starting to get on edge.

"Absolutely." said Bobby, cocking his gun, and walking towards the door. Secretly, he didn't think the door was the best idea, but they didn't really have a choice- it was the only one.

"There's something wrong." Cas called out. Bobby stopped and turned around.

"There's no angel protection. He's expecting us."

"So?" said Bobby. "We're prepared!" Cas didn't want to disagree- any time spent out here arguing was time that Dean was being tortured.

"We have to be careful." said Cas, but he was walking rather quickly towards the door. It was a void of darkness, pitch black against the grey exterior of the hell they were about to enter.

As the door closed behind them, they saw the extent of what they had taken on. The room was mammoth and empty, save for right in the middle, where there were two chairs. Not comfortable chairs or even bare wooden chairs- two metal chairs. Huge and with wires coming out of it, linked into two people- Sam and Dean. Surrounding them were several angels and several trays. Silver trays that looked like they were straight from a hospital. Filled with instruments of every manner. Zachariah was stood facing the boys, holding a particularly sharp knife.

"Castiel!" he exclaimed, turning around. "So nice of you to join us. And just in time to see your precious Dean get cut open!" He began to turn around to put the knife to Dean, and Castiel shouted.

"No!" He ran forwards towards Dean, but Zachariah thrust out his hand and Cas flew backwards.

"Oh, Bobby. Nice of you to join us too."

"Don't. You. Dare." Bobby almost growled. He held out the knife in front of him.

"Oh dear." said Zachariah. "This won't do."

"Why do you want them?" asked Bobby.

"Why?" Zachariah grinned. "Because it's fun. They ruined my apocalypse, I'm ruining their lives."

"Hate to break it to you but you're a bit late there." said Dean. Zachariah spun round to Dean, who was staring directly into his eyes. Bobby used this to his advantage. While Zachariah was distracted, he made his way over to Cas, who had been pushed through the thick metal walls of the warehouse. He was lying unconscious.

"Cas!" Bobby whispered, shaking him. "Cas!" He didn't move. "Balls!" He glanced back at Sam and Dean, who us picked up on their cue to distract Zachariah.

"Come on Cas..." said Bobby, trying desperately to wake him up. He grabbed his shoulders and shook, and Cas' eyes fluttered open.

"Bobby?"

"Yeah, hi, we ain't got time for that." He grabbed Cas' shirt and pulled him to his feet. "Work your angel magic." Bobby said, and gestured vaguely at the six angels all armed with angel blades.

"I can't do that." He said. "I need a blade." Bobby's head dropped.

"Well why couldn't you have told me before we left, when I could have done something about it?!" He said, keeping one eye on the angels slowly advancing towards them.

"I have one." said Cas, pulling a silver blade out of his coat.

"Great, now let's go." said Bobby. He stood up, followed by Castiel.

"Come at us then." He said. He stood in a strong stance, and the angels came. They ran at them both, lunging forwards to stab them. But Bobby and Cas were too fast. After ten minutes of fighting, they stood surrounded by the bodies of angels.

"Impressive, I must say." said Zachariah. "Although it isn't going to save Sam and Dean."

"Let them go." said Cas, angrily.

"Oh no, I don't think so." said Zachariah. "They're far too useful."

"What for ya great bag of dicks?" asked Bobby.

"Haven't decided yet." said Zachariah. Behind him, Dean's eyes started to flicker open. Castiel was overcome with the feeling of relief, and now that he knew Dean was alive, he would stop at nothing to get him back.

"Zachariah." He said. "I will kill you."

"Of course you will." Zachariah replied, not entirely convinced.

Cas looked over at Bobby, who nodded and began to walk towards Zachariah.

"Scary." said Zachariah. Cas could see Dean trying to find a way to break the numerous chains he was tied to the chair with, but, being chains, they were loud, and without making any noise there's only so much you can do. Cas and Bobby advanced on Zachariah. He didn't do anything to stop them. Clearly this was part of a plan.

Cas had his blade out in front of him and he moved closer and closer to Zachariah. A grin had begun to spread across Zachariah's face.

"Really? A knife? You can't kill me with a knife Bobby Singer."

"No." He said. "But he can." He pointed at Castiel, who's face was redder than a supermarket at Christmas. He was angry.

"Zachariah- why are you doing this?" said Cas as we walked towards him.

"I've explained this, you incompetent angel. For fun. They ruined my apocalypse."

"You were going to destroy the world. They saved humanity." Cas stood still in a defensive position, but with his blade still held in front of him

"And made me angry. This is what they get."

"Maybe they won't get what they deserve." said Cas.

"Oh they will." Zachariah was stood still, not even trying to attack. Cas began to close the small distance between them, and lunged forwards with his blade, but Zachariah sent him flying back into the wall.

"You are weak, Castiel."

But before he could say anything else, Sam had driven a blade through Zachariah's chest.

"Didn't see that did you?" He said. Dean had rushed to Cas' side.

"Cas!" He said. Bobby could hear the pain in his voice. "Cas, are you okay?"

"I... am fine." Cas said. Dean hugged him tightly, and Cas knew he was safe.
