Samifer

"Did he do it again?" Lucifer murmured. He sounded sleepy, but Sam knew damn well that Lucifer doesn't sleep. Sometimes it annoys Sam, because Lucifer, when it suits him, can be very impatient. Sam knows damn well that Lucifer knows Sam needs to sleep to survive, but sometimes Lucifer pretends like he doesn't. But tonight Sam is very. Very glad that Lucifer doesn't sleep. He dives back in to Lucifer's blanket cocoon and snuggles in to the warmth. Lucifer isn't shivering, which is a good sign.

"Yeah, it's just… you know… the usual," Sam mutters.

"How expensive is it gonna be?"

"Oh, it's not bed, like ten bucks or something. Castiel's just mad about the principal of the thing. He's worried their pharmacist is going to think that one of them is abusing the other, or trying to make a meth lab by the speed at which they buy medication."

"Yeah," Lucifer responded. There wasn't much to say.

They tried to not talk about it. Hell, their whole relationship was built on not talking about things. But this was different because not only was it not something one or the other of them did, it was something neither of them could stop. Castiel was falling, for real this time. And unlike Lucifer's crash landing, Castiel's grace was bleeding away. It replenished less and less when Castiel used it. Lucifer could see it was getting to a point where it was bleeding out on its own. Lucifer didn't think Castiel would have a year before he'd be as good as human.

"They'll make up," Sam said, hugging tighter to his angel.

"They always do Sam, don't sound too worried," Lucifer soothed. Maybe he was the one most affected by it all. Castiel had started falling before, but he'd been allowed back in heaven and his grace had restored. He knew what the slow bleed felt like, and Lucifer got the idea that Castiel didn't mind being more human. For certain being human meant not losing the person you loved in the blink of an eye.

But Lucifer worried, and not just about Castiel. Lucifer had never considered the slow bleed as a way to fall. He fell with all his grace intact. Even cut off from God and heaven, trapped in a place where all the warmth in the world (warmth came from his father, after all) would never touch. But Lucifer was still an angel. What would he become if he started the slow bleed, if Michael could actually kill him?

Lucifer gripped tighter to Sam and Sam kissed his brow. Lucifer relaxed a little. Sam at least knew him well enough to pick up on his signs. Sam knew when he needed a distraction. Oh well, Dean would get the blame later for Sam oversleeping in the morning, why not indulge a little?
