Ω

Dean knocks on the door frame of Cas' cabin. He's been wandering around camp for about an hour, trying to figure out how to go about this. The dark and jealous side of him kept insisting he bribe an omega girl to leave her scent all over him, maybe leave some lipstick on his neck, but he's trying to help his former mate, not make him more depressed.

The beaded curtain has been put back up, though several beads and strands were broken off by Dean when the omega broke their mating bond, and Dean feels just a little guilty about that. He thinks Cas made it himself, but he was a bit neglectful toward his friend at the time that it went up.

There's no answer, so Dean goes inside to investigate. Cas is lying on his bed, pale and sweaty, and doesn't respond when the alpha calls his name.

Dean panics and runs over to the bed and shakes him, only getting a groan as a reaction.

"Cas!" He desperately slaps the former angel in the face and is relieved when his eyes flutter open.

"Mate," Cas says groggily.

Dean has no idea how to identify the emotions that assault him at that greeting, so he pushes them all aside and sternly replies, "No."

The omega furrows his brow and rubs his bloodshot eyes, looking confused. "What are you doing here?"

Dean reaches into his pocket and pulls out a paper bag. "I have some things for you." He hands the bag to Cas who looks inside skeptically.

"You brought me drugs." He squints at Dean and tilts his head in a way that hurts Dean because he's always found the quirk so endearing.

"They're antidepressants." Dean ignores Cas' eye roll. "Take one every day. With water . And food. You don't eat nearly enough."

"Yes, sir," the omega says sarcastically, saluting. This actually makes Dean a little happy, seeing some of his friend's old spark back, even if it's in the form of snarkiness.

Cas shuffles through the bag of pill bottles and pulls out a box. Suboxone. "What's this for?"

"Drug withdrawal," Dean states, expecting a firestorm from the fallen angel.

"And why, may I ask, would I be going through drug withdrawal?"

"Because this hard shit you're taking, that you're fucking overdosing on, it ends today," Dean says with alpha authority.

Cas glares and throws the bag aside. "What gives you the right?"

"I'm the 'fearless leader' of this shithole, remember? The lives of these people people are my responsibility."

The omega crosses his arms, a classic, "you're not getting out without a fight" stance.

"Are you going to take everyone else's, too? It's only fair."

Dean honestly hadn't thought of that. His mind had only really been on Cas. He knows his ex-mate will only fight him harder if he's a hypocrite about it.

"Yes. You junkies can keep your weed, your painkillers, your fucking Adderall for all I care. But the coke, the meth, the heroin, gone."

Dean can smell a mix of anger and anxiety, the strengths about equal. Now that their bond is gone he can't scent Cas' emotions as easily, but these are powerful ones.

"Now get your crap. That's an order."

He watches carefully as Cas stumbles around his cabin like a zombie, looking in drawers and under sheets. When Dean starts shuffling through the omega's things his ex-mate shoves himself in front of him, grabbing Dean for balance for a moment before wrenching his hands away like he's about to get infected with the croatoan virus.

"You don't trust me?" he asks, clearly irritated.

"To find everything, in your condition? No."

"Keep your hands off my stuff," Cas growls.

Dean raises his hands in surrender and backs up, watching the former angel toss powders, pills, what appears to be crack-Jesus Christ- into a box.

"What about hallucinogens?"

Dean scrubs a hand over his face. He feels like he's been way too lenient on Cas already, but he doesn't want to be seen as the enemy and he can't stand the dark and angry scents that are rolling off of the omega in waves.

"You can keep anything that's all natural. 'Shrooms, whatever. But give me everything chemical. And I'd better not ever catch you streaking through the camp thinking you're chasing fairies again."

"Fairies are real, you know," Cas says matter-of-factly.

Dean pauses to think for a moment. The omega could be fucking with him, but there really isn't much that surprises him anymore. "Those ones weren't."

"It was funny, though. Even you admitted it." Castiel says, a hint of a smile on his face.

"Yeah, well, joke's over. Keep packing." He hates ruining the moment they had going, but he was about to make a flirty comment and being an asshole was the first cover-up that came out of his mouth.

Cas scowls and plops down on the floor clumsily, pulling out the box of the more mind-altering drugs from under his bed. As he sorts through his stash he tosses the harsher drugs, the LSD, the MDMA, the PCP, onto the bed, mostly missing the box he's giving to Dean, glaring at the alpha the whole time like he wishes he could still smite.

"Come on, stop being such a brat. This is for the best."

"I told you what's best for me. For you to leave me alone." Dean can hear more self-loathing in his voice than resentment toward him.

"I'm responsible for this camp, including you. I'm not here begging for you to come back. But I won't let you waste away and I certainly won't let you endanger my soldiers and civilians out there on missions when you're high out of your mind."

When Cas is finished with his hallucinogen box he goes to his bedside table and grabs a used syringe and a pack of sterile ones, a huge relief to Dean. He tosses them in the box on the bed and thrusts it at Dean's chest.

"There you go, fearless leader. That's all of it."

The alpha looks at him critically. "You swear?"

Cas puts a hand to his heart. "On my mother's grave. If I had a mother." He smirks. "Wanna cavity search me?"

Dean squints at him and backs away. He can usually tell when Cas is lying and it's usually not to him. He seems genuine.

"I'll have Jane stop by every so often and check on you."

"Right," the omega says with a smile, bouncing on the balls of his feet. "The withdrawal. Can't wait."

Dean wants to say something, wants to tell him that he'll stay and take care of him, but he can't, so he just walks out the door, throwing back a, "Take your Prozac," as he leaves.
