A/N: Dark!Klaine

Rating: Themes...possible triggering, M.

In retrospect, Kurt should have known something was wrong.

Blaine wasn't his usual self...But Kurt wasn't the one who'd noticed that. Of all people, Finn had noticed that Blaine was withdrawing into himself, becoming quiet and sullen, so very different from the excitable puppy he normally was.

Kurt had refused to believe it at first, but Finn had made him think, made him look at Blaine, and actually see the differences in his boyfriend.

But now that he was looking...

Something was wrong with Blaine.

He seemed to be tired all the time, with bloodshot eyes, complete with dark shadows under them. From the good student he'd been, now he barely listened in class, even going so far as to sleep through a couple of subjects a day.

In glee, Blaine didn't even bother fighting Finn for solos any more, happy to sit up the back whether Kurt sat with him or not. And outside of school... Outside of school it seemed like Blaine barely had time for him.

Kurt watched him for almost a week before he cracked.

"Blaine... I'm worried about you." he whispered, cuddled up next to Blaine on the couch on one of their now infrequent dates.

Blaine tensed, pulling away from him slightly.

"What's going on with you? You're so tired, all the time, and you barely sing any more... And it's almost like you don't have time for us."

Blaine sighed, curling a possessive arm around Kurt's waist.

"I'm fine." He murmured. Kurt let his head rest on Blaine's shoulder and dropped the topic, scared to start an argument in case he'd read the situation wrong.

A few weeks passed, and nothing seemed to change.

Things, in fact, got worse.

His eyes grew darker - almost sunken into their sockets, the whites now a bloodshot red. He grew tired and more irritable, and the worst part was the mood swings.

Kurt was worried.

He didn't know whether to confront Blaine about it or not. Last time it hadn't done anything.

But now people in the New Directions were beginning to notice, and they all turned to Kurt for answers.
But he didn't know anything more than what they did.

That, more than anything else, was what made him finally decide what to do.

^.^

"Hey Cooper..."

"Mmm?" Cooper muttered, feet propped up against the sofa.

"Is Blaine okay...?"

Cooper sighed. "Noticed did you?"

Kurt nodded a little, and Cooper stood up.

"Alright. He's been off for quite a few weeks now... I'm going to go check his room."

Kurt frowned. "Really?"

"I've been trying to talk to him but he won't give me a straight answer. If he comes home, occupy him."

Kurt nodded, chewing on his lip and sitting on the couch. Blaine wouldn't be home until late – he had football.

Cooper came down a few minutes later, clutching something in his hand.

"What did you find?" Kurt asked, the expression on Cooper's face making him oddly nervous.

Cooper held his hand out and they both stared silently at the object he was holding.

A syringe.

When Blaine came home, Kurt and Cooper were waiting for him.

Kurt was sobbing – he hadn't stopped sobbing since Cooper came downstairs.

Blaine dropped his bag, moving sit beside Kurt and tried to gather him into his arms.

"What did you do?" he asked Cooper, glaring at him.

Cooper sighed.

"What did you do Blaine?" he asked sadly.

Blaine frowned. "What do you mean?"

Kurt grabbed his arm, yanking the sleeve up and staring silently at the evidence, the track marks up Blaine's arm.

"Oh Blaine." Kurt burst into fresh sobs.

Blaine stared at his arm, at Kurt, and finally at Cooper, meeting his brother's sad, knowing gaze.

"Blaine, we want to help you." Cooper said softly, watching as Blaine's gaze flitted around the room, identifying possible exits. "We both love you, and want you better..." he continued, being cut off as Blaine made a dash for the exit. Kurt and Cooper both burst into action, Cooper blocking the door as Kurt grabbed Blaine around the waist, tugging him back down to sit next to him and half curling into his side.

Cooper moved to sit at Blaine's other side.

"You can't keep doing this to yourself." Kurt said softly. Blaine glared at him, at the way they were pinning him down and forcing him to stay.

"Let me go." Blaine hissed, struggling to stand again.

"Blaine, please." he cried, shaking his head. "You...you can't. Please."

"It's none of your fucking business."

"Don't pull that shit, Blaine." Cooper glared at his baby brother, hurt and pain in his eyes. "I don't care why you're doing it. But you're going to stop."

"Fuck you." Blaine growled, wrenching away from Kurt only to be pushed back down by Cooper.

Kurt hid his face in his hands, sobbing into them.

"Look what you're doing." Cooper shouted, pointing at the mess Kurt was. "Do you want this for the fucking rest of your life? You've destroyed your love life. Be fucking lucky that he doesn't break upwith you for this."

Blaine's face paled, but he continued to sneer at Cooper. "What the fuck would you know?"

"I know because Kurt's a good person, and he wouldn't stand being with a fuckup like you."

Blaine looked like he wanted to say something, instead gritting his teeth and lifting the coffee table, throwing it onto the floor. The magazines hit the ground with thuds, and a few of the coasters smashed on the ground. He stormed away, but Cooper didn't go after him this time, instead sitting on the couch and pulling Kurt into his arms as the younger boy continued to cry.

They heard Blaine stomp upstairs, throwing things around his room.

Cooper waited, petting Kurt's back until his tears finally stopped.

"Are you okay?" he asked softly, as Kurt sat up, pulling away slightly.

"Not really." Kurt shrugged half-heartedly. "I just... I can't cry anymore."

Cooper nodded, and they sat quietly, listening as the noises from Blaine's room finally stopped, being replaced by silence.

"Should we... try again?" Kurt asked, looking at Cooper.

Cooper sighed.

"Give him a few minutes for what we said to sink in... then we'll see." he decided finally. Kurt nodded, leaning into Cooper's side again for the comfort.

Moments later, Blaine stomped back into the room. He held four needles and a small packet of what Kurt could only assume were more drugs.

"Happy?" he spat, throwing the syringes onto the ground and smashing them into the carpet. He threw the packet at Cooper.

But tears just welled in Kurt's eyes. "This isn't about me, Blaine." he sobbed. "I...I want you to be happy. I don't want you to do this for me."

"Everything in my life is for you." he said almost angrily, his eyes softening slightly. "I'm not going to do this anymore. No more hits, no more... I promise you."

"Don't promise me." Kurt whispered. "Promise yourself."

Cooper glared hard at him, the drugs squashed in the middle of the fist he was balling.

Blaine felt tears welling in his eyes, glancing down at the carpet.

He nodded.

"I promise."
