"What's that Donny?" Mike asked after they landed on another rooftop.

"What?" Don asked as he pulled himself back to a standing position.

"That thing," Mike said pointing to what looked like a semi-automatic machine gun clipped to his back.

"It's a current disruptor," he answered as they started to run. They leaped over the ten foot gap and landed just behind Leo in the gravel of another rooftop.

"Why do you need that?"

"Something Raph said," Don replied, sprinting after Leo and leaping fifteen feet to another rooftop.

Mike landed behind him. "What did he say?"

"That," Don said pointing to the street.

Raph and Casey were surrounded by at least ten robotic warriors. Not foot, something different. Raph and Casey were holding their own, but only just. Most of the robots were fighting hand to hand, like slow moving street fighters. But a couple of the robots in the back had lasers and were sending red flashes toward the fighting pair every couple seconds.

"Cool," Mikey said, "Can I use it?"

"Sure," Don said, detaching in one smooth motion. "Just shoot it, like a gun. It should short circuit them."

Leo turned to them. "Mike, left, Don, right, I'll take center."

They dropped like bats and took their places. When Mike and Don were both in place, Leo closed his fist.

Mikey charged the first one, and flattened him with a kick to the back. He fell to the ground with a soft crunch.

Leo took out two with a flying kick. Then as he landed, he knocked out the legs of another with a roundhouse kick. Then he saw it. A weapon pointed right at Casey. With a grunt Leo throw his katana, nailing the robot in the face as the laser went off. The shot went high, right over Don's head.

"Careful," Don spat as he struggled with his own opponent. The robots were stronger then they looked. He fell on his back and threw him across the alley. He jumped up and moved to the next one.

Raph flashed a smile to Donny and fought on, tired as he was. Casey grunted to his left as a shot took him in the leg. Raph took out his guy and then quickly stepped in front of Casey. He blocked the metallic arm with his sai.

Mikey pulled out Donny's new toy. He pointed to the near robot warrior and aimed. The shot sent an electrical current back up his arm, but his target froze mid step and then fell over sideways.

"Cool," Mikey said and turned to take aim at another one, facing off with Leo. Again the current up the arm, and the guy fell over sideways.

"Donny, you rock," Mikey yelped as he started to take aim at the one with Raph.

Donny flew the air and crashed into the building. He was dazed for a minute, but looking up he saw the robot warrior leaning over him with a knife As the blow came down, he just managed to block it with his bo.

There was a yell. The robot was gone, replaced by a concerned Leo. Leo extended his hand, and Don took it, a stabbing pain in his left arm.

"You okay?" Leo asked turned to face the fight.

"Yeah," Don said, gripping his bo with his right.

One more shot from Mikey and the remaining robot warrior fell. They all turned in circles. Everyone was down. But just as they each felt a whoop of triumph, more approached from the end of the alley.

"No problem guys," Mikey said, striding ahead of them. "This thing is awesome."

Mikey picked off the first two before they were surrounded by twenty more metal foes.

"Round two," Leo announced as he squared off.

"More like round three," Raph shouted back.

"Who's counting?" Mikey said, taking out another one the gun. The gun started to whine.

"Mikey," Don shouted, "Drop the gun." He tried to detach himself from his attacker. As he tried to get to Mikey, the warrior slammed him and he flew across the alley again, landing on his shoulder and rolling back to a stoop.

"Mikey," Don screamed. "Drop the gun. Throw it."

Too late. The gun exploded filling the alley with a bright white flame and deafening boom. When the dust cleared, all of the robots fell over as one. Don regained his feet and saw was Mikey on the ground. He ran to Mike.

Sirens sounded in the distance. They were getting closer second by second.

They gathered around them as Don felt for a pulse.

"Is he okay?" Leo asked from over his right shoulder.

"He's alive anyway. Let's get out of here." Donny leaned over and heaved Mikey up by his armpits. Don's arm left arm throbbed and he nearly dropped his brother.

Raph gave Donny a hard shove and threw Mike over one of his shoulders.

"What the hell were you thinking?" Leo shot at Don twenty minutes later in the lair. They were crowed in the bathroom, Mike's eyes were still closed. The top of Mike's right arm was scorched from the tips of his fingers to his biceps.

"Yell at me later," Don said as he studied the burns. He muttered under his breath, "these aren't so bad… they look like second degree…"

Mike's burnt arm was resting in the cold water of the bathtub. When the skin finally felt cool to the touch, Don asked Raph to pull him out. They took him to the infirmary.

Working slowly, Don covered each of burns the with a light covering of bandages and ointment.

"Why is he still out?" Raph asked, his eyes burning into Don's scalp.

"I don't know," Don admitted.

"Is he going to die?" Raph said, with barely contained rage.

"He shouldn't," Don answered as he finished the bandages.

"Then why hasn't he woken up?" Raph shot back, louder.

"I don't know," Don said through gritted teeth.

"If he doesn't make it, I'm going to rip you apart," Raph snarled.

"If he doesn't make it, I'll let you," Don replied.

Splinter entered and joined Don's side as he checked Mikey's head. Then with a slight moan from Mike, Don found it. There was a nice sided lump on the back of his head.

Donny shook his head. Great, he thought, head trauma too. "Looks like he might have a concussion. That's explains the unconsciousness."

"So we wait and see if he wakes up," Leo summed up, his arms folded across his chest.

Don nodded. He grabbed an ice pack out of the freezer with his right arm and stuck it on the lump. "Did either of you guys see what happened? What did he hit his head on?"

"No," Leo said angrily, "The explosion took care of that."

"You might have seen it, if your ass wasn't on the pavement 20 feet away," Raph put in. "God Donny, you disgust me."

Don sighed and stared between the two of them. His arm throbbed. It was probably broken. He was going to need one of them to check it, set it. But before he could say anything, Master Splinter turned to them, with a look that Don hadn't seen in years. It left Don feeling suddenly cold.

"Leave me my sons," Splinter said simply.

"But Master," Don began, as his left arm throbbed.

"I said, leave me," Splinter said, his voice sharp, angry. Don nodded and followed Raph and Leo out into the living room.

If Splinter were angry, it was nothing to the looks on Leo and Raph's faces when they turned to face him.

"What the hell happened," Leo said, giving Don a look that he usually reserved for Raph.

"I don't know," Don said, helplessly, staring from one of them to the other.

"For a genius, you sure are saying that a lot today," Raph shouted.

"It exploded," Don said helplessly.

"Obviously," Leo said with icy calm. "Otherwise, Mike wouldn't be laying in there unconscious."

"It should have been your ass burnt to a crisp," Raph shot at him.

Don head hung in shame. He knew it should have been him using the new gun. But he wouldn't have been burnt to crisp. He would have known when to chuck the gun and duck. But he had thought, in the three milliseconds he considered it, that Mikey would have fun with it.

"You could have killed him." Leo said.

"I know," Don said dropping his head. "I didn't think…"

"That's the problem," Leo said, his voice icy, "You didn't think. And now look what you've done to Mikey. Dammit you should know better. You of all people. He didn't even know what the damn thing could do. You just handed it off, like it was some video game controller."

Don hung his head, he couldn't bring himself to look them in the eyes.

"An exploding video game. You're going pay for this." Raph growled.

Don looked up in time to see Raph heading toward him, but before Raph could strike, which Don was going to let him do, Leo darted between them.

Don was relieved until Leo said, "Not here, Raph. Let's take him to the Dojo."

Don looked between them, Raph's face burning with rage, Leo's face icy cold. He swore under his breath and he did the most logical thing that came to mind. He ran for the door.

He wasn't fast enough. Leo caught him easily and twisted his aching arm behind his back.

Don screamed out in pain, almost falling to his knees. But Leo managed to half march, half drag him to the dojo.

"If you think that hurts you shit for brains, wait til I'm done with you," Raph growled.

Leo pushed Don in the middle of the room.

"No weapons," Leo said to Raph as he threw his katanas into the mat. Raph followed suit with his sai's but he looked reluctant.. The both came at him as one. Don shut his eyes and let the punches and kicks knock him off his feet. He ended up sprawled at the far end of the room, his face planted in the red mat.

Raph strode over and pulled him back onto his feet. "Fight back, dammit."

"Why?" Don said, side stepping the kick that Raph sent at his face. "I can't beat one of you, much less both of you. Especially with only one arm. But if will make you feel better to beat the crap out of me, go ahead. You can't make me feel any worse than I already do."

Raph yelled and knocked Don to knees, then jumped and hit him hard in the back, sending Don sprawling again landing again on his painful arm, he yelped in pain despite himself and rolled off of it.

Raph pulled Donny to his feet one more time. Raph stared at him as Don cradled his left arm in his right.

Raph yelled, kicked Don hard in the chest and then stormed out of the dojo. A few seconds later, they heard the front door slam.

Don found himself by the wall. He sat up and leaned against the wall. His arm thumped painfully, he was sinking a pain induced stupor. He closed his eyes and rested his head on the wall.

From somewhere above Leo asked, his voice still icy. "Is your arm broken?"

Don shrugged, not opening his eyes. "I think so." It was pulsing with pain at every heartbeat, there couldn't be any other reason.

Leo knelt next to him, running his hand over the lump on Don's left arm. He roughly pushed on the spot. Don winced and nearly yelped.

"It's broken." Leo said, his icy look fading somewhat.

"Can you set it?" Don asked.

Leo hesitated, "You'd be better off having Master Splinter do it. Come on." He pulled his brother to his feet. "But you're not off the hook."

"I said, don't not disturb me," Splinter yelled as Don walked back in the infirmary. "If there was any thing I needed, I would come to you. Get out of my sight."

His master's voice was cold, furious.

Don dropped to his knees and fixed his eyes to the floor. "Sensei please," Don began.

"No." The sharpness in his father's voice made Don look up. "When your brother have hurt each other, it is bruises, cuts, scrapes. When you hurt your brothers, I am faced with this." Splinter gestured to Mikey still unconscious behind him.

"It was an accident, I didn't mean for it happen."

"And yet it did. The greater the ability, the greater the responsibility, the higher price to pay. Go to your room, Donatello and do not leave it. Think about your actions. If your brother requires you, I will send for you."

"Father, please," Don begged. His arm thudded.

"GO."

Don went, briefly making eye contact with Leo as he past the dojo on his way to his room, cradling his arm. He dropped down on his bed and tried to make himself comfortable. Finally, he sat up, crossed his legs leaned against the wall.

No sooner then he had started to focus his breathing to help relieve the pain, then he heard his door open. He opened his eyes. Leo stood there, looking somewhere between concerned and disgusted.

"He didn't realize you were in pain," Leo said in lieu of a greeting. "He's coming."

"Thanks," Don mumbled, closing his eyes. The door closed with a quiet snap.

Splinter came a few minutes later. Don cringed at the sight of him. Splinter eyes held nothing but anger. Splinter hadn't been angry, truly angry, with Don for years. Don had made sure of that. He knew exactly where Splinter's line was and he always stayed far from it. He hated it when Splinter was disappointed with him. He couldn't stand it when he was angry with him.

Quietly and gently, Splinter moved his hand across his arm, feeling the bone underneath the muscle. A soft sigh escaped his lips, "Is this what you were trying to tell me when you intruded on my silence earlier?"

Don just nodded.

"It is broken, my son. I will set it. Leonardo."

Leo appeared from the shadows near the door. "Yes master."

"Please hold your brother. This will be quite painful."

Leo nodded, giving Don a long look. Leo pulled Don to his feet and then crushed him a bear hug, pinning his good right arm under his hands. Splinter took Don's left arm and gave it a jerk.

Don screamed and his knees buckled, but he didn't fall. While the rest of his body felt like goo, Leo's arms kept his shoulders and arm still. Splinter accessed the break, feeling the bones and then gave him another jerk. After several repetitions of this, Splinter finally nodded.

Leo sat Don back on the bed. Splinter handed bandages a few sticks to Leo and said, "Immobilize that my son. I return to my other charge, and my silence," Splinter said giving them both a meaningful look.

Leo looked sympathetic as he splinted Don's arm and wrapped it the bandages. "You look awful," he commented.

It took most of Don's willpower not to fall over. He trembled from head to foot, but he knew that Splinter's ministrations had done the trick. He could feel that the bones were back in the right place. Now all he had to do was heal.

When Don didn't answer, Leo continued, "If you get any paler, you'll pass for human."

"Sure, the shell and all," Don said dryly. "I'd be fantastic."

Leo finished and Don finally slumped into the bed.

"If Mikey's wakes up, I'll let you know." Leo said while heading to the door.

Then Leo stopped suddenly and turned around, "Where do you suppose those robots came from? They didn't look like foot."

"I don't know. Maybe there is something on the robots themselves. A manufacturer, or something like that."

"Good idea," Leo said. "I'll get Raph on his cell and have him swing over there. See if there is anything left."

"I'm sorry, Leo," Don said before he could leave. "I didn't mean for this to happen. I didn't mean to hurt Mikey."

Leo gave him a look of frustration but then it softened into something more like pity. "I know you didn't. But that almost makes it worse, doesn't it."
