Hey guys! I had this idea in mind for awhile and finally wrote it out. It is my new two-shot! I always wondered, because Mikey and Casey both tend to do reckless things, what would happened in Casey ever did something reckless and it hurt one of Raph's brothers, what would happen? And that's how this was born!

I hope you enjoy! Let me know what you think or if you have a question! This is chapter one of two!

Third Point of View:

It was a Labor day weekend and the turtles offered April and Casey to spend the weekend with them at the lair. Both agreed since it was admittedly one of their favorite places to be other than home and since it had been awhile since they all spent time together other than trying to save the world from Shredder or mutant menaces, they thought why not?

Casey was on edge from a terrible week at school and he was itching to start spending time with Raph and his brothers. He needed to let out some steam cause he felt like he was going stir crazy from not going anywhere outside of school and his house.

Plus Raph was the only one that he could wrestle around with and not worry about hurting. He couldn't play around like that with his little sister or April, so he felt he could really let loose with Raph. The same could be said for Mikey since Leo and Donnie weren't the type to just wrestle around for the heck of it.

So Casey bought enough soda to last a week and hurried to the sewers. He knew the path by heart now and was coming up on the lair entrance in less than 15 minutes.

"Hey Casey!" Mikey beamed, turning to greet him from where he stood by the pinball machine. Raph was also at the machine and looked over Mike's shoulder to grin at him.

"Hey man."

"Hey guys!" Casey grinned toothily and Mikey laughed when he saw all the bags of soda Casey was carrying with him, "Hey, I hada make sure I had enough!"

"Oh that'll be enough," Raph rolled his eyes and both brothers helped him take all the soda to the kitchen where a surprised Donnie greeted them. He had a mug of coffee in his hands.

"Sup Donnie," Casey greeted with the same grin he had before.

"Hey, how much soda did you buy?" Donnie asked incredulously and everyone laughed. Shaking his head, Donnie looked at Casey, "Where's April?"

"She said she was grabbing some pizza," Casey shrugged.

"YES!" Mikey cried, jumping for joy. Casey and Donnie laughed at the hyper turtle while Raph smirked, "So are we having a movie night tonight?!"

"I'm down for one," Casey said as he tilted his head, "What movies ya got in mind?"

"Hmm, good question!" Mikey laughed, "I'll go look at what we have!"

With that, he burst out of the room, almost pushing Leo over in the process as he was coming in. Leo looked startled before shaking his head and smiling at Casey, "Hey Casey. How are you?"

"I'm great!" Casey beamed, giving a thumbs up, "I'm so ready for the weekend! School was sooo terrible!"

"I bet," Donnie teased and Casey shoved his arm, "Well I'm gonna go finish some notes. If I don't finish them now then Mikey'll drag me out later."

"Right," Raph scowled, "Ya better hurry then. Cause yer not stayin' in yer lab all weekend again."

"Yeah, yeah, Raph," Donnie rolled his eyes and he walked out of the room. Leo went for the cabinets and began making some tea.

"I bought some soda and you're still gonna drink tea?" Casey asked in amusement, "Let loose Leo and drink some soda!"

"I will later," Leo laughed, smiling, "I always drink tea after I meditate."

"Well if you say so," Casey shrugged and Raph rolled his eyes. They both startled at Mikey's shout.

"April! Yes! You're the best sis ever!" He cried and Leo huffed out a laugh as Raph groaned. Casey grinned when Mikey came barreling in with the pizza, April right behind him with a smile.

"Hey guys," She greeted as Raph helped Mikey get the paper plates out, "I made sure to bring enough pizza for tonight at least."

"You mean for the next couple of hours?" Leo teased and Casey laughed.

"That's right dude!"

"Basically," April agreed, laughing herself before she glanced around the room, "Where's Donnie and Sensei?"

"Sensei is still meditating," Leo answered.

"And Donnie's finishin' some notes in his lab," Raph answered over his shoulder as he playfully nudged Mikey in the side.

"I'll go let him know I'm here and to come get some pizza!" She beamed before trotting out the door. The others began to get some pizza and soda. Master Splinter, Donnie, and April came sometimes during that time and got their share before everyone began eating in the pit.

"Okay! For now I can put on something funny!" Mikey boasted as he pressed play, "So I figured we'd watch Happy Gilmore!"

Raph snorted into his drink, making Casey and Leo laughed, "We haven't seen that in forever!"

"I remember that!" Donnie nodded, looking pleased, "It was okay."

Even Master Splinter enjoyed the movie as they all ate their dinner. Casey and Mikey went back for more pizza and then Raph and April convinced Leo to drink a whole can of soda. He almost got sick and ended up burping so much that Donnie, Mikey, and Raph were in hysterics. Casey cracked up just thinking about it again.

Master Splinter eventually went back to the dojo and Leo went to run through some katas with him. April followed Donnie into his lab so that she could help him sort all his paperwork. Raph, Mikey, and Casey were the only ones in the pit.

"Man, I'm getting bored of this," Casey sighed as he stared at the wrestling episode Raph put on. Casey laughed when Raph sent him a glare, "So I guess that means ya don't wanna do nothing else right now."

"Nope," Raph scowled, shaking his head as he focused on the TV.

"I'm gonna take a quick shower. Then maybe we could play a game or something!" Mikey offered with a big smile as he turned to Casey. Casey was suddenly hit with warm feelings; it was the same type of feelings he got around his little sister.

"Sure," Casey smiled toothily as he relaxed in his chair, "I'll think of somethin' to do while you're gone."

Mikey beamed and jumped away to go take his shower. Casey blinked when he glanced at Raph and saw some sort of sideways smile, but it was gone as quickly as it came.

Casey shook his head and peered around the room, trying to figure out what he could do for fun while Raph was busy and Mikey was gone. His eyes stuck on Raph's training dummy and his eyes lit up at an idea.

"Hey Raph! Can I borrow some of your...uhh...those throwing knives?" Casey asked, feeling stupid when he forgot what their called.

Raph threw a weird look at him and chuckled, "My kunai or shuriken?"

"Uh...either!" Casey grinned stupidly and wondered what the difference was in his head. Raph rolled his eyes and sighed.

"Those aren't toys ta play with Casey," He scowled and Casey's face fell, "I don't think ya should use them."

"I'll just try throwin' them at your practice dummy," Casey pouted, crossing his arms. Raph rolled his eyes again.

"No deal, Casey...at least not tonight," Raph grumbled as he looked slightly annoyed. Casey internally huffed. What was the big deal about it?

"Hey Raph!" Donnie called from his lab and Raph groaned loudly.

"What Donnie?!"

"Can you help me and April moved some things around in here?" Donnie called with slight amusement.

"Ugh! Fine!" Raph growled as he got up quickly and rushed to help them. He left the TV on and everything. Casey frowned after him and then looked at his practice dummy.

Raph was being stupid. Why couldn't he practice throwing that kunai or whatever? It's not like it was hard or anything! He'd seen Raph do it. Casey frowned deeper and felt like his friend was being slightly unfair.

Making up his mind, Casey got up and went over to Raph's practice dummy, moving it slightly out of view of the lab. He moved it closer to the small pool and by the hallway. Nodding with satisfaction, Casey grinned and walked into the dojo, surprised to see Leo practicing diligently.

"Uh, sorry to interrupt," Casey called awkwardly and Leo paused, flicking his serious gaze on him, "Where do you keep your uh...kunai?"

"Our kunai?" Leo blinked, surprised, "Why?"

"I was gonna practice throwing them at Raph's practice dummy with Mikey! It'll be sooo fun!" Casey grinned. His face fell slightly when Leo's face hardened.

"I don't know...will Raph be watching you guys?" Leo asked and Casey took a moment before answering because he felt insulted. He and Mikey didn't need a babysitter! It was like they didn't even trust him!

"Yeah," Casey lied before thinking it through. There wasn't time to take it back if he wanted to because Leo nodded, looking relieved as he moved to the corner with shelves. He pulled out a few kunai and handed them over to Casey's waiting hand.

"Be careful. Make sure Mikey doesn't overdo it either," Leo warned and Casey nodded before rushing out of the room. The kunai were a little heavier in his hands than he thought they'd be.

He tested them in his hands and put the other 5 in his pockets before readying the first one. He paused to make sure Raph was still preoccupied before throwing the first one tentatively, just to try it out. He didn't use enough force and it bounced off, hitting the floor with a clang.

His heart stopped in his chest and he froze, waiting for Raph to come out and yell at him, but he never did. Casey sighed in relief and readied another one, "They make this look so easy..."

He threw the next one harder, trying to find the right ratio to make the kunai stick into the dummy. He gasped when the second kunai hit the dummy below the target, but it only barely stuck in this time.

"I didn't think I'd need to throw it so hard to get it to stick," Casey frowned, contemplating the practice dummy. He grabbed a third one and got ready to throw it. This time it hit the dummy close to the last kunai and fell. Casey groaned. He still had two more.

Maybe when Mike got out of the shower he could show him how to work this better! Casey grinned and grabbed the fourth kunai from his pocket before readying it. However, he hadn't heard the bathroom door opening when he threw the last one.

Casey applied more pressure and went to throw the kunai but he accidentally stepped on one of his loose shoelaces when he took a tiny step forward and he stumbled right as Mikey came into view from the hallway.

Almost as if it were slow motion, Casey watched the kunai sail through the air just as Mikey entered the room. Mikey, through years of ninja training, managed to sense something and instinctively leaned away, putting his arm up. The kunai hit the underside of Mikey's arm near his wrist with a sickening splotch sound that made Casey sick to his stomach.

"Ahh!" Mikey shrieked loudly, crouching down and holding his arm above the injury. Casey felt all the blood pool into his stomach and he turned cold as he gazed at his best friend's little brother. The little brother he just hurt.

"What's going on?" Casey froze, sweating bullets when he heard Leo behind him suddenly, "Oh my God, Mikey!"

Leo rushed past Casey and knelt next to Mikey, his eyes wide from shock. Leo's cry enticed the others to come rushing into the room. April paused and gasped at the scene. Donnie gasped too before he went flying to Mikey's side. Raph, however, froze as he looked down at Mikey to Casey and then to the kunai littering the floor beneath his practice dummy.

Raph's gaze turned cold and his face started darkening with rage. At that point, Casey was sure he was in the middle of a panic attack as his chest rose and fell way too quickly. He felt pale and he was extremely close to vomiting. Despite all of this, he couldn't look away from Raph.

"YOU IDIOT!" Raph screamed with eyes wide in rage, startling everyone, "I specifically TOLD you that you shouldn't mess around with the kunai. WHY would you go behind my back and do it anyway?!"

The more he screamed the redder he became. Leo looked at him with large eyes before he glanced at Casey. Donnie's eyes were wide as he gazed between the two but his attention was stolen when Mikey spoke.

"I-I'm okay..." Mikey tried to soothe but it only made things worse because his blue eyes were pricked with unshed tears and blood was running down his fingers onto the floor in a small stream. Casey went numb with horror as he gazed at the small turtle.

"Get him to the lab!" Donnie growled, anger growing in his own eyes as he looked at Mikey and understood what happened. Leo, April, and Donnie struggled to help Mikey up and into the lab. Casey didn't dare move as Raph's furious gaze was pinned on him. A gaze that he'd seen Raph use on the people he nearly killed on patrols and missions was now pointed at him.

He still felt numb and horrified. He wanted to throw up. He just threw a kunai and hit Mikey. Casey jumped when a hand rested on his shoulder. He looked up into the disappointed gaze of Master Splinter before Splinter rushed into the lab. That made Casey break down.

"I-I'm sorry," Casey stammered as he couldn't tear his eyes away from the blood on the floor, "I-I'm s-sorr-"

Before he finished his sentence he was punched in the face so hard he stumbled, half twisted, and fell to the ground in shock. He looked up at Raph standing above him with a glare from hell on his face. Suddenly he felt like the enemy as Raph looked ready to strangle him to death.

"How could you?" Raph growled, obviously struggling not to hit Casey again, much to Casey's shock, "You could have killed my baby brother!"

At that, Casey was sure that Raph was never going to forgive him. Feeling horrified, helpless, and shocked, Casey felt tears prick his eyes but he'd be damned if he'd start crying in front of Raph. Casey gasped when Raph grabbed a fist full of his shirt and hauled him up to get in his face. He was sure Raph was going to hit him again.

"Raph!" Leo called, clearly shocked to see what Raph was doing as Leo entered the room. Raph's rage filled eyes looked over at Leo and Leo was stunned into silence for a second. He'd never seen Raph look like that towards a friend. The last time he'd seen him look like that was when they fought the Shredder.

"He could have killed Mikey, Leo!" Raph growled and then he shoved Casey towards the ground with a harsh thud, "Mikey could have died because of some stupid decision Casey made!"

"I-I'm sorry," Casey mumbled desperately, looking towards Leo instead of Raph, "I'm so sorry! I didn't mean to! I didn't think-"

"Yeah that's the problem!" Raph yelled at him, almost kicking him, "What were ya thinking would happen?!"

Casey let his head fall with despair and Leo looked at April when she came through from the lab to see what was happening. She gasped and flew to Casey's side, pushing Raph back with force.

"Raph! I know you're mad but this is taking it too far!" She frowned and then froze when Raph glared at her too.

"Mad? MAD!? I'm pissed off! I just can't BELIEVE he went behind my back to do something so STUPID!" Raph shouted and Leo rushed to Raph's side just in case he lost it.

"Okay, okay, why don't I take Casey to my house until you calm down?" April frowned, almost in shock over how mad Raph was towards Casey. Raph fists shook so bad that it looked like it was taking Raph everything not to hurt Casey.

Raph said nothing but glowered at Casey and Leo sighed, nodding to April. April helped Casey up and Casey let her lead him out of the lair without any reluctance. He wasn't even man enough to look back. He felt too bad. Oh man, he just hurt one of his friends and now he was going to lose his best friend!

Raph watched them leave, his fists shaking by his side. He desperately felt the need to hurt something. He tensed when Leo put a hand on his shoulder. He turned and put a hand on Leo's shoulder in return, "Don't touch me right now, bro, I'm too pissed off."

Leo blinked but dropped his hand and Raph let go as well, "Maybe you should let out some steam in the dojo?"

"Yeah...let me know if Mikey needs me," Raph said through clenched teeth and Leo nodded, watching Raph go, still partially shocked at what he had witnessed. Leo sighed, rubbing his face with his hands before turning and going back into the lab.

Leo entered the lab to see Donnie stitching Mikey's arm carefully. Mikey was watching the process but it was like he was thinking heavily about something because he wasn't focused. Sensei was standing by his side with a hand on his shoulder throughout the process. Leo walked further in and stopped at Donnie's side, looking at Mikey's arm.

"How is he?" Leo asked aloud, horrified by the old blood stains covering Mikey's arm.

"He'll be alright," Donnie answered tightly and Leo blinked, surprised to see the anger in Donnie's eyes, "It hit his arm so hard that it almost went through it but it didn't so at least both sides of his arm don't need to be stitched."

"This is good," Sensei said soothingly, his hand tightening on Mikey's shoulders, bringing Mikey out of his thoughts. Leo watched Mikey carefully but felt alarmed when tears filled Mikey's eyes again.

"Are you okay?! Does it hurt?!" Leo panicked and Donnie's eyes widened when he saw the tears in Mike's eyes. Mikey shook his head and tears got soaked in his mask so he pushed it up with his good hand, "What's wrong?"

Mikey sniffed, trying so hard to keep in the tears that there was an uncomfortable lump in his throat, "Raph..."

"What about Raph?" Donnie pressed, finishing the stitches and setting the tools aside so he could sit beside his little brother and pull him close. Mikey looked at Donnie.

"Raph is really angry at Casey..." Mikey said sadly, tears rolling down his cheeks, "I ruined this weekend!"

"You did not, my son," Sensei soothed, looking worriedly at his son and rubbed at his shell to calm him down.

"Yeah, it's Casey's fault for ignoring Raph's warnings and foolishly throwing kunai without a guide," Donnie ground out, anger coloring his tone. Leo nodded in agreement and Mikey rubbed his eyes.

"Y-Yeah but it was just an a-accident and I didn't dodge in time," Mikey frowned, unable to stop crying, "I've never heard Raph like that."

"Me either but he's right to be angry at Casey," Leo said, pressing close to Mikey to comfort him, "Don't worry, little brother."

"I just don't want him to lose another friend and it be because of me," Mikey cried as he snuggled closer to Donnie, who frowned worriedly over his head, "I'm not mad at Casey so he shouldn't be either! It was just an accident."

Leo sighed and Master Splinter hummed, "I will go talk to Raphael, my son. Don't fret. I am sure brother will forgive him."

Mikey nodded, sniffing hard to stop the tears as Donnie hugged Mikey closer. Leo hopped up to be on Mikey's other side as Master Splinter left he room. Leo gently grabbed Mikey's face so he faced him, "You know it's not your fault, right Mikey?"

"But-"

"It's not your fault," Leo repeated seriously, his blue eyes steely, "Do you understand?"

"Y-Yeah..." Mikey answered, feeling tired suddenly, "I-I understand..."

Leo smiled warmly and nodded, letting go of Mikey's chin and hugging him, holding him close, "Good. And don't worry about Raph. Sensei will talk to him. It may take some time but I'm sure he'll forgive Casey."

"W-What about you two?" Mikey asked hesitantly, peeking out of Leo's embrace to look at Donnie. Anger flashed in Donnie's gaze.

"I...I'll try. But if he ever does something stupid like that again I don't think I'll be able to," Donnie ground out.

"Me either," Leo said with a startling calm rage in his eyes. Mikey gulped nervously.

Hopefully Raph would calm down enough and so would his other brothers so that Casey could come down again and apologize. Mikey wasn't mad, in fact he felt extremely bad for Casey. He heard the whole thing with Raph and heard how angry Raph was with him.

Mikey was sure that Casey would never forget this and possibly never forgive himself. That alone should be reason enough to forgive him. And most of all, Casey was Mikey's friend too and he didn't want to lose him because he bros couldn't forgive him.

Whoa, that was intense! Poor Casey and poor Mikey, too! They're both so upset! But Casey did something extremely stupid without thinking of the consequences.

Will Raph be able to get past the fact that Casey hurt Mikey because of a poor choice, even if it was by accident? It's what Mikey wants but sometimes things don't work out the way you want it to.
