While the turtles were eating Splinter and Shen went to the dojo to talk and to wait for the boys. Splinter held his wife and told her.
"This is going to be wonderful if it works, but what is your plan if it doesn't work?"
Shen smiled up at him and said.
"Then I want our son to mutate me into a rat so we can indefinitely be together."
Splinter held her at arms length and said.
"You would become a rat just to be with me? Honey you do not have to do that, I am happy with the way you are and with the way I am. It should work, we can hope."
She looked over at the dojo clock and said.
"We should get going, the boys will be in there soon."
Splinter had felt confident in his decision about becoming human again until he saw the orange content of the beaker on the lab table and Donatello standing next to it. The young 15 year old looked just as nervous as his father walked up to him.
"Son, how is this supposed to be given?"
Donnie looked up at his father and around at the rest of his family.
"Its supposed to be injected, Kirby had to have it dropped on his head because the vile broke."
In saying Donnie got out a syringe and filled it with the liquid, Splinter rolled up the sleeve of his robe and sat on the stool so his son could reach him. Donatello tried to keep a steady hand as he put the needle to his father's arm.
Splinter could see his hesitation and told him.
"Donatello, just focus on the task at hand, concentrate. Just like in your ninja training, do not worry about hurting me my son, I am a lot tougher then you think."
Donatello looked at his brothers and new found mother and then back to his father, he gulped and stuck the needle into his father's arm and pushed the retro mutagen into his father's system.
The affects were not imideate but it did happen, Splinter grabbed his arm that got injected and cried out. Going to his knees he continued to cry out as his fur began to shrink along with his nose. With in a few minutes black hair replaced brown and small human ears replaced long brown ears.
They all watched as Splinter turned back into a human before their very eyes, after the transformation was over Homato Yoshi sat on the floor panting heavily holding his chest.
All four turtles surrounded their father as he continued to gasp for air and cough in pain.
Shen was at his side and asked.
"Are you alright? How do you feel?"
Yoshi coughed again and then said between gasps.
"I- I- am fine. Just give me some room."
After a few minutes he went from being on his hands and knees to sitting up, he looked up at his son and said.
"I think it worked."
He got the strength to stand and felt off balance at first, after fifteen years of having large feet standing on normal human feet was alien to him.
Donatello took his BO off his back and handed it to his father as a walking stick, Yoshi took it and used it.
Being able to fully stand now he wrapped one arm around Donatello and told him.
"Thank you my son."
He then turned and gave each of his other sons a hug as well before settling on hugging his wife, she reached up and gave him a kiss on the mouth.
Mikey had to say it.
"Awe, its a Kodak moment!"
Yoshi had tears of happiness rolling down his cheeks as he laughed at his youngest son's joke, he turned around and looked around at his family.
He looked down at his hands and was so happy to see human hands, but he took note at how dry his skin looked after all of these years.
Donnie let out a breath he didnt know he had been holding and asked his father.
"How do you feel?"
Yoshi turned from his wife and other sons to look at his most inelegant one.
"I feel human, thank you my son, you have made an old man very happy."
Mikey looked up at his father and asked.
"SO like, how old are you?"
Leo and Raph both wapped him upside the head but no one scolded them this time.
Yoshi walked over to the mirror on the wall by the sink in the lab and looked at him self, putting a hand on the side of his face he studied his looks in the mirror and said to his family.
"I don't look much older then I did before I got mutated."
Shen walked up behind him and wrapped her arms around him saying.
"Honey I have told you before I do not care what you look like, now lets go give your body some food since the boys have been fed now."
He turned from the mirror and looked at his family, he could still see the worry in Donatello's eyes and asked him.
"What troubles you Donatello?"
Donatello had been lost in his own thoughts and wasn't paying attention, looking over at his father he just said.
"Nothing Sensei, I was just thinking."
Shen looked at her new found genius son and said.
"Penny for your thoughts?"
Donnie looked over at her but didnt say anything, Shen walked over to him and placed her hands on his shoulders.
"Donatello, it worked, there is no need for worrying your self, he is fine look."
Donnie looked over at his father, it did appear that he was fine, but he didnt know for how long. April didnt report that her father had any complaints about turning back human.
He looked off to the side then said softly.
"I know your right. Come on lets go fix him something to eat."
Yoshi walked over to his second youngest son and told him.
"Thank You Donatello, I feel fine, so do not worry about me my son."
Yoshi gave him a hug and held his son for a moment and then they parted and the family went to the kitchen.
Shen made her husband something light for breakfast, as she and him sat down to eat, the turtles went to the living room.
Raph looked over at his genius brother and asked.
"So ya think it will stick Donnie?"
Donatello had been paying attention to Space Heroes and looked over at his brother.
"I think it will, but if not I will try again."
Leo turned to them and told Donnie.
"Sensei told you if it doesn't work not to worry about it."
Donnie looked back at the screen and let out a sigh and told his brothers.
"Your right Leo, I shouldn't stress over it."
Donatello deep down hoped that the reverse mutation would stick with his father, he didnt want to disappoint him a second time.
A/N: Well what do you think? Splinter is now human, for now. I know in the episode Donnie said that it would take him months to make more. Well that was with the idea that he would need 10 canisters of mutagen, this is from my imagination that they decided to get some from Baxter's lab. Review please and give me your input on Tang Shen's idea to become a mutant!
