Hey! Don't worry, I'm alive. So, this is the second to last chapter. Sorry! Never mind. By the way, none of you got the 'which way the beans went in the tin' reference, it was from comedian Jon Richardson, really funny man, you should check him out! Anyway, on with the story!

By the way, I decided to include leatherhead in this chapter, although I have only seen him in 'good genes', so he might be a little bit OOC. I also don't know what his lab looks like.

See chapter one for disclaimer.

Donatello ran as fast as he could down the sewers, until eventually he stopped and jst burst into tears. He sank down the wall, crying and rocking himself gently. At some point dug his nails into himself and bit his lip so hard it bled.

Then a voice said from above him. "Donatello, my friend. What is the matter?" Through tear-filled eyes Donatello looked up to see Leatherhead looking down at him, concern evident in his eyes. "I heard you screaming."

He'd screamed? When had he done that? The purple-banded turtle tried to explain what had happened, but found himself unable to get the words out and just ended up breaking down again.

Leatherhead himself frowned a little at that. He'd never seen his friend like this in all the time he'd known him. The tech-lovin turtle had always seemed to calm, well-presented and collected. Now he looked none of those things. Of course, there was the question of what had happened. Has he been attacked? Probably not, apart from his lip nothing was bleeding. Then again he was hardly in a position to exanimate him…unless…

"Donatello, my friend I am going to take you back to my lab, alright?" The alligator stated. He felt given the circumstances precise, clear instructions were needed.

He waited until the turtle had shakily nodded before scooping him up and carrying him back to his lab. He noted Donatello wrapped his arms around his neck, like a scared child.

After putting him on the examination table, Leatherhead checked Donatello over properly. After stemming the bleeding from his lip, all Leatherhead could conclude was that he'd had a panic attack. Now the next question was what had caused it…wait. His brothers, did they know?

Leatherhead quickly searched for his phone which was typically not where he thought it was, but a couple of minutes later and he was ringing Leonardo.

"Hello?"

"Hello, Leonardo."

"Leatherhead? Sorry, but this isn't a great time, Donnie's disappeared and sensei….let's just say he isn't exactly over the moon….oh! Can you keep an eye out for Don?"

"I can do better than that. I can tell you where he is. He's with me in my lab, recovering from what appears to have been a panic attack. Care to explain what happened?"

"As soon as we get there, yes."

Five minutes later and all three remaining brothers were in the alligator's lab, having given Leatherhead a quick recap of what had happened.

"Has he calmed down now?" Raph sounded sarcastic, but the worry was evident in his eyes.

"Yes, h is asleep though. Would you like me to wake him up?"

"I'll do it." Mikey cut in, going over to his immediate older brother and shaking him gently. "Don? Doooonnn? Wake uuuppp."

After a bit more shaking Don did eventually wake up, pulling himself to a sitting position he glanced at his brothers. "Why am I in Leatherheads lab?"

"You appear to have had a panic attack. What's the last thing you remember?" Leatherhead himself said, from a corner of the lab.

"I fell…then I heard Mikey telling me that I was him and he was me." Don put his head in his hands. "It was confusing, and I had so many ideas, and I couldn't write them…where's my notebook?!"

"Sensei has it." Leo said immediately, not wanting to risk another attack. "He's back at home."

"Home?"

"Yeah, you know that place with the garage and the dojo and the kitchen where we have pizza." Mikey smacked his beak before continuing. "Although I'm not surprised you don't remember it, considering you spend about half the day in your lab."

Don smiled sheepishly. "Sorry. Are we going home then?"

"Yeah, I suppose so. See you leatherhead." Leo turned to leave, however…

"Hold on a minute, panic attacks are no light matter. I want to observe you for at least the next week." Leatherhead informed Donatello, sternly.

"Leatherhead, I have a lab, I can do that myself."

"Donatello, my friend, I know you, you will say everything is fine when it isn't. No, I will observe you. Then I know you are alright."

Seeing there was no arguing with him, Donatello sighed in agreement and all four brothers headed back home.

Halfway down the sewers though, Leo stopped Don. "Hold on a minute don, I have a question, well, two actually. One, why did you run? And second why do you invent so much?"

Don paused and considered before slowly saying. "I invent to keep myself calm. You have meditation, Mikey had cooking, and Raph has biking. I invent. I ran…because it got so confusing. We were all being each other, and I could handle it for the first few days, but then it just went on to long. So I guess I broke down. I'm sorry; you must think I'm a right wimp."

Leo immediately pulled his brother into a hug, while Raph and Mikey patted Don's shell, comfortingly.

"We don't think you're a wimp." Leo said gently. "We all have our limitations, and I guess we found yours. Six days of name-slash-personality-swapping."

"Right. So now we've had this bit of brotherly…love…bonding…or whatever the shell you wanna call it, shall we go talk to sensei?" Raph said.

"Sensei?"

"Yeah, he wanted to talk to you after we brought you back. So prepare yourself." And with that Mikey swung the lair door open.
