What if Eve wanted to destroy Heaven and Hell?

"OK, we'll go in and you two stay out here and shoot if she comes out," Dean said.

"Well, at least the plan ain't complicated," Bobby muttered as he and Cas watched the brothers head into the diner where Eve was.

Sam and Dean walked into the diner and looked around. They approached the counter and sat down. Sam took out his phone and scanned the other occupants. "Crap, crap, crap," Sam said as he observed their eyes.

"Is there anyone in here who isn't a flesh eating monster?" Dean asked under his breath.

"Us," came the unwanted reply.

"Let's get out of here," Dean suggested.

Cas and Bobby were nervously waiting outside. It was especially hard on Cas. He had had that brief period before Lucifer and Michael's fall when he was completely powerless, but he had been extra souped up lately and it was hard to have his power knocked out.

Bobby snuck a look at Cas. He had been worrying him all day. Something seemed different about him. He wasn't completely sure if he trusted him right now. Because of his preoccupation, he didn't notice as two of those Jefferson Starships seemingly materialized right behind them. Bobby took a moment to roll his eyes. That was the last time he was giving dean naming rights.

A Starship grabbed him and dragged him off away from the diner, while the other one dragged Cas off towards the diner.

Sam and Dean got up to leave. The door swung open and Cas was forcefully shoved in. At the same time, one of the Starships came up and dragged Dean out.

"Sam!" Cas and Sam heard Dean shouting.

"Dean!" Sam shouted back. In his experience nothing good came of them being separated.

"I wouldn't worry about him," a young waitress said as she came out from behind the counter.

"Eve?" Sam and Cas both asked.

"That's right. Now, Castiel, you've been very naughty."

Sam shot a look at Cas. He betrayed nothing, though. Playing poker with angels must be rough.

Eve started speaking in Anokian. Cas's eyes glowed bright white and he moaned.

"What are you doing?" Sam asked.

Eve didn't answer, but continued her incantation. When she was done a final burst of light burst forth from Cas and he sank on to the floor.

"Cas, are you alright?" Sam asked.

"He's not Castiel any more," Eve explained. "I sent him up to Heaven."

"Why?"

"All in good time," Eve promised and nodded to one of the Starships. Before Sam had a chance to look over, everything went dark.

Dean was dragged along until they arrived back at the jail. He was thrown into the cell with Bobby and they were left alone.

"Where's Sam?" Bobby asked.

"Last I saw back at the diner with all the monsters and Cas," Dean said. He was looking through his pockets to see if he had anything he could open the cell door with, but he knew it was useless. Those stupid Starships had taken everything off of him.

"Any idea why they separated us?" Bobby asked.

"No." Dean had thought it was odd. Why hadn't they just killed all of them back at the diner? Or even back at the bar? That could only mean that Eve wanted something. That thought chilled Dean to the bone.

When Sam woke up he was chained to a cot in what looked like a basement. He saw Cas on another cot across the room. No, not Cas he remembered.

"Jimmy?" he asked.

Jimmy groaned and came awake.

"Are you OK?" Sam asked.

"I guess," Jimmy answered. "What's going on?"

"Well, what do you remember?" Sam asked.

"It's fuzzy," Jimmy admitted. "Castiel got exorcised, right?"

"Yeah, if that's the word for it," Sam said.

"Well, I'm glad to be rid of him," Jimmy admitted.

"Yeah, being possessed by an angel is kind of nauseating," Sam agreed. He remembered when Lucifer was possessing him, he had just zapped off to wherever the fallen angel had wanted to go. It was like being on a really bad roller coaster. He had always wanted to throw up, but not being in control of his body he couldn't. He was pretty sure Lucifer didn't feel the sensation and of course wouldn't have cared what Sam felt.

"That's not what I mean," Jimmy said. Castiel has been doing some very bad stuff lately.

"Like what?" Sam asked.

Before he could answer, Eve entered the room.

"What do you want with us?" Sam asked again.

"It's simple. Castiel and Crowley want to find Purgatory and use it for Heaven and Hell. In order to stop them, I'm going to destroy Heaven and Hell."

"You make it sound like they're working together," Sam noted.

"They are," Jimmy and Eve said together.

Sam was stunned. If just Eve had said it, he wouldn't have believed it. But Jimmy had no reason to lie. And Cas had been acting strangely lately. He decided to worry about that later. "How are you going to destroy Heaven and Hell?"

"There's a ritual. You have to mingle the blood of the vessel of Hell's boss and Heaven's boss. Hell's boss is Lucifer. I don't care what Crowley thinks, Lucifer is still very much in charge. He's just letting Crowley have enough rope to hang himself with. And with Michael down there with him, the current winner of the war would be the boss of Heaven."

"I thought Cas was losing?" Sam asked.

"That's what he wants you to think. In reality, he's got Raphael running scared. Anyway, I just need to sacrifice both of you at Midnight. Heaven and Hell will be destroyed. All the souls for both of them will come to me in Purgatory and then I can open up the door and we'll take over Earth."

"You can't do that," Sam protested.

"I can. And I will."

"Did you kill Dean and Bobby?" Sam asked. If they were still alive, there was still room for hope.

"Of course not. When I take over the Earth I will need to mate with a human in order to bring them both together. I think Dean will make the perfect father of my child."

"He'll never go along with that," Sam said. But, he was relieved to hear his brother was still alive.

"He won't have much choice."

"What about Bobby?" Sam asked.

"He will be our child's first meal. If you'll excuse me, I need to get some things ready for our ritual." She smiled and left.

Sam tugged on his chains to no avail.
