Promise Kept: Donnie
Donnie Kidnaps Mikey
Donnie P.O.V.
I'm always interested in learning new things no matter what it is. Medical knowledge is the most valuable thing I can learn. I was watching TV with Raph and Mikey when I heard about a condition that I don't think I've heard of before, seizures. I figured that I would research it to feed my curiosity. I went into my lab to do research on my computer. I found quite a bit of information on the net, but one thing that caught my attention was how this one guy developed seizures due to the fact he had been hit in the head extremely hard one to many times. It made me instantly think of Mikey, he's always being hit in the head by Raph. I need to find a way to protect him from this, then it hit me I could put him in a plastic bubble. After thinking about it I thought no he could roll it around and hurt himself. Hmmm I know a plastic cube here in the lab to where I can keep an eye on him.
With that in mind I got to work. I had enough stuff lying around to build it, and not to mention it won't take me long at all, just a couple of hours. I started my work, I built the frame first it was, and I had enough room in my lab to where I could build it to be 6'X6' to give him plenty of room to move around safely. After I built the frame I secured it to the floor, then I inspected it making sure that there were no sharp edges. Next I took some large sheets of plastic that I had and attached them to the frame. Some pieces weren't big enough so I had to sew them together and in the middle of one side I attached the zipper but it was on my side so Mikey couldn't sneak out. There it was finally finished after three hours of work and I can keep Mikey safe. As I stood back and admired my work, I heard the tell tale signs of Raph and Mikey getting into a fight, and I thought Oh no! Mikey!
Normal P.O.V.
Donnie left Mikey and Raph to watch TV. Mikey just couldn't help himself there was a movie he wanted to watch that he found very funny it was Eight Legged Freaks as son as he turned it on Raph freaked majorly. Mikey knew his bro didn't like bugs and he did it on purpose, as soon as Raph started to freak out he started giggling. Raph lunged for Mikey, but Mikey was too quick and took off running. Splinter and Leo were in the sewers on a one on one training session and Donnie was in his lab leaving Mikey to deal with Raph's rage by himself.
"RAAAAAAOOOOOOOOOOOOOOOOOOR, MIKEY I'M GONNA KILL YOU!"
Giggles could be heard throughout the lair. Raph continued to chase Mikey around the lair; they knocked over chairs and broke lamps. Don stepped out of his lab hearing all of the commotion and saw what he feared was about to happen. His one thought was a promise they all made to protect Mikey from everything even each other. Raph had Mikey pinned to the floor on his plastron about ready to smack him across the head. Donnie didn't think or say anything as he ran forward. He lunged at Raph and tackled him to the floor, with reflexes that rivaled Mikey's he was up before Raph could understand what happened. Don ran back towards his lab, he grabbed Mikey up and tossed him up to carry him knowing that he would protest. Making it into the lab before Raph could catch them Donnie locked the door and put Mikey on his feet and said as fast as he could, "Okay Mikey I need to keep you safe from hurting yourself, I was gonna put you in a plastic bubble but it would move around too much and you could get hurt so I made a plastic cube instead", and he shoved Mikey in and zipped up the cube.
Mikey just stared dumbfounded before he looked at Donnie like he lost his mind.
Meanwhile Raph was getting up, "What the shell happened?" Then he heard something that made his blood run cold it was a scream from Mikey, but what made it worse was what Mikey said in his scream, "Donnie you've finally lost your mind, let me out of here."
Raph was up and running to Donnie's lab door. When he got there he yanked on the door finding he couldn't move it. So he started to bang and yell.
"What's goin' on in there? Donnie let Mikey go? What are ya doin' ta 'im? Donnie answer me?" He got no response so he continued pounding on the door trying to get an answer then he pulled his sias out and tried to take out the door that way. After ten minutes Leo and Splinter came home and heard the commotion.
