"Lucifer, can you shut the hell up?" Dean asks, exasperated.

Lucifer, who had been quietly humming Kansas' "Carry on my Wayward Son" over and over for the last hour, starts humming louder just for that. His humming turns to a groan as Crowley attacks him, not for the first time since Gabriel told him to stop.

"Crowley!" Gabriel barks.

"What? It's not like he's helping," Crowley says defensively.

"And neither are you," Gabriel reminds him.

It's true; for the last hour or so, everyone has just been sitting around the war room brainstorming a way to defeat the Darkness. So far, no one has had any bright ideas, but it doesn't stop them from trying.

Lucifer hasn't spoken once throughout the conversation, instead sitting as far from them as possible while still being in the war room and humming to himself. Though it had been fairly soft, it still carries in the quiet room, and though no one mentioned it at first, it was getting on everyone's nerves.

A part of Castiel is happy Dean decided to ask Lucifer to stop, but at the same time, he sort of isn't. He doesn't like the archangel; far from it. In fact, he actually hates Lucifer, and has every reason to. But Castiel's sense of compassion outweighs his desire for revenge, and even he is getting sick of watching Lucifer in pain.

Lucifer, recovering from Crowley being... him, stands up and walks out of the room. Crowley and Gabriel call after him, the latter with much more compassion, but they're both ignored. They all hear a door slam, and it's evident Lucifer decided to pretend to be a teenager and lock himself away. At least he won't be bothering them.

Dean sighs softly and rests his head on Castiel's shoulder. "I think we finally found the one apocalypse we can't stop."

"I doubt that," Castiel replies. "There's a way. I know that." All they have to do is get Chuck down here.

"Even the archangels think it's hopeless," Dean reminds him.

"Not hopeless," Gabriel corrects him, even though the conversation didn't include him. "Just... highly improbable."

"So, pretty much this is a suicide mission?" Sam surmises, frowning.

"Yep," Gabriel replies.

"Then why bother?" Crowley asks.

"It would be suicide to do nothing, too," Gabriel reminds him. "I say we at least try to do something. What's the worst that could happen?"

"And what, exactly, would this 'something' entail?" Crowley asks him. "Or are you just throwing around words without a single plan to back them up?"

"This is why I hate demons," Gabriel says to no one in particular. "I mean, I'm not really buddies with most of the other angels, no offense to you guys, and I'm not particularly fond of most humans, no offense again, and I don't really like witches, offense intended —" This earns a glare from Rowena, only putting a smile on Gabriel's face. "But demons are quite possibly the most annoying things I've ever met."

"Then it's a good thing my entire life doesn't revolve around pleasing an arrogant, overconfident moron like you," Crowley replies.

Gabriel gasps in an overly sarcastic way. "You don't spend every second of your life trying to make me happy? Crowley, I'm offended. I thought we had something here."

"I don't know which one of you I hate more right now," Dean mutters.

Gabriel gives him an exaggerated smile. "Aw, Dean! That's the nicest thing you've ever said to me!"

"Enough!" Ellen yells, silencing everyone. She can be really freaking scary. "If you don't have something helpful to say, shut the hell up."

No one speaks after that, which is nice because there's no more bickering but at the same time, it means no one has any ideas.

Dean sighs and rests his head on Castiel's shoulder. Castiel puts an arm around him as if it will bring any comfort to the boy who's finally losing hope.

"We'll figure something out," Castiel assures him. "We always do."

"But what if this is the time we don't?" Dean asks. "I mean, how do we know that we'll always save the world, just because we always have? What if this is the time we can't sweep up our mess?"

"We'll figure something out," Castiel repeats, his voice final. He means it, too. The djinn wouldn't just let him die in here. It would lose him. Unless that's how his dream ends; the djinn gives up on him when it can't get anything from his vessel anymore and lets Amara kill him when his body dies. But can he die in here? He's an angel; they don't die by any normal means. Could this dream last forever? Could he spend eternity in here with Dean? He'd have to find a way to make Dean live forever, but he's sure it's possible. It has to be. Right?

"I hope we do," Dean mumbles.
