Donatello yawned turning the final screw into the newly repaired VCR. The unfortunate machine had been one of the casualties of the fight between Raph and Leo.

His workbench was littered with the pieces to the other innocent bystanders that had taken the brunt of his brothers' frustrations. Sometimes…just once…he wanted to drag Leo or Raph in here and make them repair whatever it was they had broken. Then, maybe they'd be a little more careful or at least take the fight to the dojo where nothing could get damaged.

There was a knock on the door. "Donnie?"

The soft voice made Don jump slightly and he turned. "Leo. Where have you been? You look like crap."

A small wry smile tugged at Leo's mouth and he walked into the lab. "That's ten times better than I feel. Where is everyone?"

Don stood up motioning Leo to a chair. It looked like his brother had taken off before anyone could tend to his fighting wounds. "Raph went to bed early which I don't think was his idea. Mike is at a late movie and I thought Sensei was waiting up for you in the living room." As he spoke, he went to a cabinet to get something to clean the wounds.

Leo shook his head sitting down. He knew better than to try to talk "Dr. Donnie" out of his intended task. "No, thank god." He ignored the look Don gave him. He also knew Don well enough to know his brother wouldn't repeat anything he'd say. Kind of like a doctor/patient confidentiality thing.

Don pulled a chair over sitting in front of Leo to take care of the cuts and scrapes on his face. "So. Where did you go?" He touched the antiseptic pad to Leo's forehead.

Leo made a face that was almost a wince at the sting. "Running. Nowhere really."

"Uh huh," Don nodded looking at Leo's hands. "Hmm, I don't know what looks worse. Your hand or Raph's eye." He could sense there was more that Leo wanted to tell him, but he wasn't going to press.

Leo didn't smile at the comment. Not because he particularly regretted giving Raph a black eye, but his thoughts were elsewhere at the moment. His brother's voice called him back and he looked up. "I'm sorry Don. What did you say?"

Don spoke very slowly enunciating each word. "Is. There. Anything. Else?"

Leo hesitated. "Yes. No." He sighed. If there was anyone he could trust right now, it would be Donnie. And Don would be the only one who could tell him what the dart had been tipped with. "Yes," he said finally reaching into the pocket on his belt and held up the dart.

Donatello frowned. "Talk Leo. Talk fast." He took the dart carefully and studied it. Ordering his brothers around wasn't really Don's forte, but when it came to things like their health he was prepared to make exceptions.

Leo tried not to look embarrassed as he spoke. He had been bested by an enemy he hadn't even seen. It was a miracle he was still alive. "I was about five miles from home when I sensed someone watching me." Leo sighed failing to keep the heat from creeping to his face. "I didn't even see who shot it at me. I was unconscious maybe for ten minutes or so."

"It hit you? Where?" He knelt down examining the small pin hole Leo had motioned to on his leg. It didn't look to be swelling like some poisons would cause it to do. Don exhaled slowly. "Ok." He got to his feet and crossed the room searching through various drawers and cabinets grabbing things.

Leo watched him curiously. "What are you doing?"

"Going to do a blood test," Don murmured. "And see if I can find what the dart was tipped with. You don't know who it was? I doubt the Foot would have left you alive unless…" He turned. "…they planted a tracking device on you."

Leo gave Don a surprised look. "I wouldn't have come home unless I checked myself over for tracking devices. Come on Donnie, you know me better than that." But, Leo reasoned with himself. It's not like you've been acting like yourself today. Why wouldn't Don be worried?

Donatello was kind enough not to point out that obvious fact and walked back to his brother taking a little blood from his fingertip. He put it on a glass slide. "This will take awhile. I would feel better if you stayed here so…"

"What is going on?" A softly accented voice spoke from the doorway.

Leo and Don both looked up at their sensei who was regarding them with a puzzled expression.

Leo instantly felt heat rising to his face again. "I…"

"I'm just making sure Leo's cuts get cleaned out, Sensei," Don said smoothly turning away the slide palmed in his hand. "Going out running is all fine and good, but New York isn't exactly the cleanest city."

Splinter turned his attention to Leo. "You were out running? For three hours?"

Leonardo's eyes darted away from his teacher's for a moment before he met them again and murmured. "Hai."

Splinter studied him suspiciously. "When you are through here I would like to speak to you in the kitchen."

Donatello tried to look both occupied and uninterested as he set the slide on the table out of sight, but he heard Leo's soft, "Yes Sensei." He turned when the door closed behind Splinter and saw his older brother's eyes slide shut.

"Thanks Donnie," he whispered. "The last thing I needed…"

"No problem, Leo," Don interrupted walking back over to him. He folded his arms watching him. "But you know I'll have to tell him if the dart was tipped with anything."

Leo's eyes opened and he nodded as he got to his feet. "I know."

Don gave him a small smile. "Good luck. I'll let you know when I get the results. And if you feel anything odd, let me know right away."

"I will," Leo promised heading to the door. "Thanks again."

Don shook his head watching his brother leave. "Yeh. All part of the service."
