Clint bit his lip harshly, dammit it hurt! He couldn't bring himself to look at Natasha, his eyes were watering from the pain and he didn't want her or any of the others to see the wetness pooling in his eyes. It was definitely a full through fracture, those hurt the most. Clavicle breaks were always tricky.

"Collarbone."

Clint hissed softly, blood dripping from his mouth, more specifically from his lip, he'd bitten hard enough to draw blood. Natasha cursed fluently in Russian under her breath as he extended a hand to pull him to his feet, they would have to go to the ER for this break. Clint nodded and let Natasha yank him gently to his feet. The rest of the Avengers just gaped at them until Tony found his voice.

"What the fuck is going on?!"

Tony asked, looking at the pained look on Clint's face and the concerned look on Natasha's. Natasha opened her mouth to say something but Clint glared at her to shut up. She just ignored him and motioned for Bruce to come over.

"Clint has OI."

Natasha explained, rolling her eyes at Clint as she said so. The archer was staring daggers of anger at her. Awareness dawned in Bruce's dark brown eyes and he hurried over instantly. Steve, Thor and Tony just looked confused though, Tony was the only one who felt like voicing his confusion however. But it was drowned out by Bruce's surprised gasp.

"Osetogenesis Imperfecta? What Type? Did you get a break?!"

Bruce whispered as he looked Clint over, gently. The pale archer just glared at him, clutching his shoulder and arm to his chest like it was his lifeline. As an answer to Bruce's question, Clint raised a single eyebrow, as if to say 'Why-else-would-I-be-holding-my-arm-like-this?'.

"Type 1, borderline severe. Yep..it's a clavicle break."

Clint sighed softly, and Bruce's eyes widened. He whipped his head around frantically, as if looking for something. He found it on Tony, his oversized MIT sweatshirt. He motioned for Tony to take it off.

"We need to use it to splint his shoulder."

Bruce added, as a way of explanation. Tony raised an eyebrow but he didn't question it, just by looking at the sweaty, pale archer, he could tell that Clint needed it more than him, much more. Bruce asked Clint if he could walk and the archer nodded, but when he tried, his legs were noodle-like and wobbly. If it weren't for his braces holding him upright, he probably would've fallen and broken something else. Yet Clint persisted, if it weren't for the arm that curled around his waist and scooped him up and off the ground, he probably would've passed out. Steve had been the one to pick him up, and most of the Avengers looked at him in concern and worry.

"What is the oseteothingie have to do with this?!"

Tony asked, looking at Natasha for an explanation and she was more than happy to provide it. She looked at him solemnly when he said it.

"It means that he has Brittle bone disease."

They ended up waiting in the waiting room of the ER for a while, mornings were always the worst time to go. There weren't enough doctors or nurses to go around, so they had to wait a while before Clint could be taken care of. The archer lay propped up against Steve in the uncomfortable hospital issue chairs, he was still sweaty and pale as he hugged his arm to his chest.

Steve was getting angrier and angrier at the fact that the medical staff wasn't helping their friend who was in obvious pain. He was tempted to go over there and demand that Clint be seen, now. But it was as if the archer had read Steve's mind because he sent the super soldier a look that clearly said for him not too. Yet two hours later, when Clint was almost definitely going to pass out, Steve leaned over and grabbed Tony's upper arm. Getting the genius' attention and shooting him a knowing look.

"Tony, I don't care what you do, cause a scene if you need too. Just get him seen."

Steve hissed and Tony sent him a sly smile with a conniving look on his face.

"You got it, Cap."

Throwing a scene is almost what ends up happening, as all the staff members Tony tries to reason with are pathologically unhelpful, repeating on monotone that Clint will be fine and will just have to tough it out.

"Look, you idiots! He has a chronic bone condition! He has just broken his collarbone and is about to pass out! Give him something, at least look at him!"

Tony cried and the nurses just rolled their eyes and responded flatly, just like they did over and over.

"We can't give patients anything until a doctor sees them sir. Otherwise we'd get people who just come in to get high."

Tony was ready to yank his hair out by the roots, why couldn't these people understand that he was trying to get their help?! Finally he thought of an idea, he just hoped that Clint wouldn't just kill him afterwards. He did not appreciate the thought of getting hung in his sleep.

"Please! He's my little brother! I hate seeing him in so much pain, just look at him."

Tony whimpered, softly and one grandmotherly looking nurse looks at them, and then at Clint in concern. He can almost hear her icy demeanor melting at the horribly pitiful sight.

"I'll see what I can do."

She whispered, tentatively.

-TimeSkip-

"No! I'm not wearing it!"

Clint growled, looking at the offending article of clothing with a sneer. The offending clothing is a hospital gown in Clint's size, a blue tinted hospital gown covered in multicolored bears. It was obliviously aimed at a much younger patient than Clint and Tony couldn't stop laughing, behind his hand of course.

Not long after Tony went all 'scary big brother' on the hospital staff, Clint found himself curled up on a stretcher in the middle of the ER hallway. They still didn't have any rooms available for non-life threatening cases, but Tony somehow managed to convince them to start treating him anyway. At the moment 'treatment' just involved a child's dose of Tylenol, a Barney themed ice pack and the accursed hospital gown.

But the pain really was excruciating, yet it wasn't something Clint hadn't experienced before. He was used to such pain. But then again, it was slowly reaching that level that even he couldn't handle. A fresh stab of sharp pain came from his collarbone and he couldn't help but let out an involuntary whimper.

Finally he consented and slowly changed into the gown, once he was dressed and situated, The Avengers' eyes widened as they looked at their archer. He looked like a child sitting on the gurney, dressed in a childish hospital gown. Steve felt a pang of sympathy for the archer, he just looked so helpless that it tugged on the heart strings. Clint looked up in surprise as the nurse from earlier hurried back.

"You're in luck! I found a doctor who knows a lot about Brittle bone disease. He gave me permission to give you some intravenous bisphosphonates."

The nurse explained and Clint nodded dizzily, leaning back onto the pillow behind his head. He honestly felt like he was about to vomit.
