Leo shook his head vigorously, rubbing water out of eyes that were still stinging like fury. Raph offered him a towel, but he jerked away from him.

"That did not go as planned." He said more to himself than Raphael.

"Leo - that was out of hand! I think we really hurt them!"

"I'm not having this conversation with you." He replied shortly, stalking out of the kitchen.

"Leo? Where are you going?"

"Out." Was all he would say, and stormed through the darkness into the tunnels.

Raph rubbed his temples in frustration and anxiety. What was happening? He didn't like Leo with a temper. Tentatively he glanced into the window of the Lab, and could see Mike bent over Donatello. He knocked on the door lightly, and Mike scowled in his direction.

"We're closed!" He yelled.

"I wanna help Mike." Raph said slowly.

"Go away."

Raph turned and started for the stairs, but something made him hesitate. He had a strong feeling that he shouldn't leave them, no matter what they said. He spun around and instantly returned to the Lab, in time to see Mike stumble to the floor as he was crossing the room. Raphael hurried inside, catching him as he tried to rise unsuccessfully.

"Ah!" He cried instantly. "Not the arm! Let go!"

He quickly released his hold on his shoulder, but continued supporting him around the back. "I'm sorry! I'm so sorry Mike!"

"Save it!" He answered through gritted teeth. "I need...to get sick."

He could tell he was bad off - he hadn't even pushed him away this time. Swiftly Raphael helped him over, and bit his lip guiltily as his brother threw up. At the end he was so weak he couldn't hold his head up anymore.

"C'mon. Bed." Raph said gently drawing him back to his feet. Mike said nothing - he wouldn't even look at him. As he laid him down, Raphael stared openly at the damage he had inflicted. His left eye was nearly swollen shut, and he was strangely pale. His right shoulder was clearly distorted and need attention badly.

"Have you called Luke?" Raphael asked Mike.

"The phones aren't working." He answered flatly. "And Donnie's worse off than me - so see if you can help him."

He got up from Mike and went over to see Donatello. His eyes were clenched tightly shut, and he was openly trembling. Raphael lightly felt his forehead with the back of his hand. He was clammy - that was never good. Maybe he needed more blankets.

Don's eyes opened slowly, a dazed stare that struggled to focus. "Mikey..." He called softly.

"No, it's me Don." Raph replied. "I'm going to get you some water." He picked a bottle out of the fridge and brought it back to him. He started to try and help him sit up, but it made the pain so intense he could hardly breathe. With his help he managed to take in a few drops, and then his dark eyes narrowed slightly at Raphael.

"What is wrong with you guys?" He demanded.

"I'm really sorry Donnie."

"What's up with Mike?"

"Um...I'm not sure. He's throwing up...getting weaker by the minute. He said the phones aren't working?"

"Hm? The phones?"

"Yeah, the cell phones. He said he tried Luke."

"Tried him?"

"To call him." Raph clarified, concern growing. Donnie wasn't all there.

"Oh. Maybe Jenna could call him."

"She's at school, isn't she?"

"Where?"

"Donnie close your eyes. You need to rest - I'll be back in a couple minutes. I need to check on Mike."

"Where is he?"

"He's across the room."

"I was supposed....to fix the phones..."

"Donnie you're not fixing anything right now. Don't even move. I'll be right back." Raphael cursed inwardly as he ran back to Mike, whose own eyes were closed now. "Mike? Please say you're still with me."

He looked up instantly. "Yeah..."

"That's good, because Donnie isn't. He's confused, his mind is...I don't know what to do."

"We may have a real problem." Mike said quietly. "How is his breathing?"

"I don't know...not normal. And he's colder than he should be. I was going to grab some more blankets."

"Do that. Top shelf, right closet door."

Raphael moved to obey, grabbing two more for Donatello and one for Mike. "Maybe I should go get Luke - find him myself."

"Better to send Leo. Somebody has to stay with Donnie, and I honestly don't think I can get back up right now."

"Yeah, that would work but...he's not actually here."

"Leo ran off?" Mike asked sharply.

"Yeah."

"Oh, that's perfect. Great. Raph, you absolutely can't leave him."

"But I don't even know what to do Mikey." He said anxiously.

"If his breathing gets really bad, he needs the Oxi. You've seen him use that for a couple of us, remember?"

"Is it around?"

"Over by the computer. Bring it here, and I'll show you which button turns it on. You need to keep a close eye on him."

"What about you?"

"Just bring me the trash can, because I'm going to get sick again."

Jenna had tried the phones several times after her last two classes were canceled - there was some kind of interference on their end. She decided just to surprise them and show up. When she reached their den she tried knocking, but got no answer. She typed in the code on her phone, holding it up to the scanner to let herself in.

When she walked into the Den, she stopped abruptly at the sight that met her eyes. The room was torn apart. They didn't always clean up things immediately (what teenage boy does?), but this looked somehow different than usual. It was quiet - unsettlingly so. The only light was coming from Donatello's Lab, so she headed towards it. Through the window she saw Raphael, looking somewhat haggard as he moved from one end of the room to another. She knocked on the window, and he jolted upright in surprise. He literally bolted out the door to greet her when he saw who it was.

"Oh thank God!" He said breathlessly. "I'm so glad you're here! Please tell me you have your phone!"

"Of course I do - Raph, what's wrong?"

"I need to call Luke now. Don and Mike are hurt...it's a long story, I'll tell you everything, but–"

She shoved her phone into his hand before he could finish, and dashed into the Lab to see them for herself.

Shaking slightly, Raphael dialed Luke and waited impatiently for him to answer.

"Hey - how's the college girl?" Luke said good naturedly.

"Doc it's Raph, I'm using Jenna's phone, ours are actin' up. We need you down here, like...now. Don and Mikey are really hurt."

"Raph, what's going on?" He asked swiftly, and he could hear the Doctor throwing some things together in the background. "What happened?"

"I wanted to get ahold of you hours ago. We were working out together today and...I don't even know how to tell you this. Leo and I, Doc we hurt 'em."

"How did you hurt them?"

He choked back a sob as he tried to go on. "I don't...I didn't mean for this to happen."

"Raph, I need to know what I'm walking into."

"I did something to Mike's shoulder - he can't use his right arm at all. He probably has a concussion - he's gotten sick so many times I stopped keeping track. He's so weak he can hardly move."

"What about Donnie?"

Raphael sighed very deeply. "He's bad Luke. His right knee is totally messed up, he's in horrible pain. He's out of his mind...not making any sense when he does talk. He's been using the Oxi for about two hours, still not breathing really well." He paused to compose himself from another sob. "I'm sorry! God, I'm so sorry! I wanted to come get you myself, Mike said I couldn't leave Donnie alone!"

"Where's Leo?" Luke asked pointedly.

"He left after the spar, haven't seen him since. With the phones acting up, I can't even call him."

"I will be there as fast as I can!" Luke finished, and hung up.

Jenna knelt beside Donatello anxiously, tears springing to her eyes as she stroked his forehead. "Donnie?" She said softly. He groaned at her touch, but didn't open his eyes. "It's going to be okay." She said, more confidently than she felt.

"Jenna?" A startled voice called to her from across the room. The woman rose, hurrying over to see how Mike was doing.

"You're early?" He asked under some duress. "I thought you'd be awhile yet."

"Couple classes got canceled. Tried to call but..."

"I know, the phones aren't working. But go back to Donnie - he needs you."

"You look like you need a friend too Mikey."

"Is Luke coming?"

"Raph's talking to him, I'm sure he'll get here." She answered, and at that moment, Raph re-entered the Lab.

Clearing his throat nervously, he asked Jenna to come over to him. "I need to tell you something."

She got up from the floor to meet him as he hesitated by the door. "What is it Raphael?"

"There's just something you should know. Don and Mike...they weren't hurt by an enemy."

"Then how did they–"

"The four of us have a one-on-one, every other day. Leo and I went way too far."

"What?"

"I'm trying to tell you that it's our fault."

"But..." She trailed off, a shocked expression over her features. "How could you?"

"There's no excuse." He answered shamefully. "But that's how it happened."

She took a sharp breath, looking away from him. "I don't know what to say. Where's Leonardo?"

"He's not here."

"He left them?"

"Jenna there's nothing I can say...except that I'm really, really sorry. I didn't mean for this to happen."

"Who attacked who?"

"Like it matters?"

She gave him a piercing look, and then softened somewhat. "There's enough negativity in the atmosphere. Maybe we shouldn't talk about it right now. Doc's coming?"

"Yeah."

"I'm going to sit with Donnie. Why don't you see what your other brother needs?"

Raphael picked up another water from the fridge and returned to Mike. After several small sips he focused on Raph for a long moment without saying anything.

"Can I ask you why?" Mike finally said.

"I'm guess I was trying to prove what a tough jerk I am."

"Mission accomplished." Mike said wryly.

Luke burst into the den a few minutes later, making for the Lab with all haste. He went to Donatello first, as Jenna scrambled to get out of his way. His pulse was weak, his breath coming in shallow gasps, even aided by the Oxi. Luke examined his eyes carefully with his pen-light, muttering something sharply under his breath.

"Doc..." Jenna started softly.

"He's in advanced shock. We have to move him now - he needs an IV." Luke pulled blankets off of him, nearly cursing out loud when he saw the state of his right leg. "You have got to be kidding me!" He exploded, struggling to keep his anger under control. He took a deep breath, forcing himself to calm down. "Okay. One second." He ran over to the closet to find a brace, returning swiftly. "I want to get this on him first. Moving is going to hurt period, but it might help to keep it locked. Raph - come here. Jenna, get the other bed pulled back, and grab the IV unit out of the closet. Then get out a unit of blood from the fridge - they're clearly labeled, he takes the positive one."

Jenna got going immediately while Luke applied the brace as gently as he knew how. Regardless, his face was a grimace of agony, whimpering softly.

"Don - Donnie I'm sorry." Luke said evenly. "We have to move you, okay?"

"Sensei..." He moaned, hardly aware they were even there.

"Shh. Brace yourself Donnie, because this won't feel good. Raph, get on the other side and we're going to lift him on three."

He counted off and they lifted together. Donnie let out a long slow groan, clenching his teeth as they carried him across the room. His breathing slackened again for a few seconds, and then his eyes seemed to actually focus on Luke.

"Doc..." He rasped with difficulty. "My chest is killing me...I can hardly breathe."

"I know Donnie. I'm here now, I'm gonna take care of everything, okay?"

"Where's Mike?"

"He's right here - he's fine...or he will be." Luke said honestly.

"Why does everything hurt? Where's Sensei?"

Luke got down on the floor beside him as Jenna wheeled the IV over, and retrieved the blood he'd asked for. "Donnie, listen. Listen to me. You need to relax. Close your eyes, and try to let go, okay?"

"Okay." He whispered weakly, attempting to release the tension screaming in every muscle.

Luke hooked up the IV, and started a blood transfusion as soon as he could. Once it had started flowing he set up a couple more pieces of equipment to monitor his vital signs, and began looking further into his levels. He spent a solid forty-five minutes making sure Donatello was on the road to stability before turning over to Mike.

He had a vacant look in his eyes, but snapped to attention when Luke said his name.

"Doc. How's Donnie?"

"He's in shock - we're getting it under control. I need to have a look at you now. Can you follow my light?"

Mike struggled to stay with the penlight, only managing to make one pass out of several attempts. Luke examined his shoulder carefully, while running a couple more tests.

"I need to address this - " He told Mike quietly "And the sooner, the better."

"Then do it." He answered bravely.

"I think I should give you a sedative first."

"Do I have to?"

"I know they do some weird things to you guys...but this is going to hurt, and I can't guarantee I'll get it right on the first try."

"You're the doc...Doc." He agreed with resignation.

Luke set up their own solution and gave him a localized injection. While he was waiting for it to take effect, Mike sat up a little bit more.

"It feels weird. I mean, the pain in my shoulder is there, but the rest of it's been numb or sometimes kinda tingly since the fight."

"That's normal." Luke assured him. "Take a few breaths, get good and calm. Then I'll get to work."

Jenna wordlessly watched the monitor gauging Donatello's vitals. She'd never seen his body so rigid or tortured - and it had her worried. Raph sat down nearby, feeling completely lost and ashamed. Luke caught his eye for a second, before turning back to Mike.

"How are you holding up, besides the physical?" He asked him quietly.

"Okay...I guess. I'm not as angry as I thought I'd be with Raph. I don't really remember a lot of the spar."

"I'm guessing it's been awkward. It's not easy being in the same room with him right now."

Mike looked at him seriously as Luke probed the socket of his shoulder. "Luke, you go as hard on Leonardo as you want, but take it easy on Raph. I can't believe what he did anymore than you can but..but the fact is he came back. I don't know what would have happened...if he hadn't been here." He punctuated the last word with a cry as Luke adjusted the bone back into the socket.

"It's okay, it's okay." Luke soothed. "The worst should be over."

He breathed out deeply and then nodded. "Yeah...oh....that's better. Oh thank God."

"I'm going to get some more ice on it, and I'll have to put it in a sling. You won't be able to use it for awhile."

"Thanks Doc. Keep me updated on Donnie...I'm worried about him."

At that very moment he was stirring again from a troubled sleep, whimpering softly in pain. "Leo..." He mumbled. "Stop! Leo..."

"Shh." Jenna tried to calm him. "It's alright."

"Let go." He moaned incoherently. "Let me go!"

Jenna rose as Luke came over. "He's not resting Luke - he's suffering. Can he do drugs?"

"He's going to have to. Give me a second - I'll be right back." He started setting up another needle while Jenna stayed with him. When he came back he injected him with a heavy dose of the sedative, and monitored his breathing a few moments longer. "I still don't like how he sounds. I'm going to start him on a respirator." Luke told Jenna as Donatello slipped into unconsciousness.

Jenna leaned over him, lightly brushing her lips over his. "I'll see you soon." Then she moved aside so Luke could work. "I'm going to make some coffee - you want?"

"I'd drink some. Meantime, I'm going to take some scans of his knee and find out how much damage Leo caused."

She paused at the revelation, and then shook her head. "I'll be back in a bit."

When she walked into the kitchen she was startled to see Leonardo, standing over by the sink. Rubbing water out of his eyes, he didn't seem to notice her immediately.

"Where've you been?" She demanded, seething anger rising immediately to the surface.

He looked at her with a scowl when she stood in his path as he tried to walk out.

"I don't answer to you. Move." Was all he said.

"Do you have any idea how badly you hurt him?"

"Donnie's a big boy, he can fight his own battles. Move!"

She reacted instantly without thinking, slugging him so hard in the jaw that he actually hit the floor. Shocked, he raised a hand to his bleeding mouth as Jenna shook the pain out of her own hand. "As soon as he gets off the respirator, I'll relay your message." She proclaimed, and stormed out of the kithen. He struggled upright, swiftly pursuing her.

"Wait! Now wait a minute! Jenna!"

She whirled around to face him with a scorching glare. "Why should I?"

"What did I do?"

"Besides the obvious, he's been having trouble breathing for hours! The phones aren't working, Raphael couldn't leave him to get help! So while you were off sulking, or whatever you want to call it, he was going downhill fast!"

"I...I didn't know–"

"You didn't know you hurt him? C'mon Leo, I wasn't born yesterday!"

"I didn't know I hurt him like that, I wasn't trying to--"

"I'm really not interested in hearing anything else you've got t' say. Don't come near the Lab - if Mike sees you he's liable to lose it."
