A/N: I own the turtle tot in this one too, the series of turtle tots for the turtles goes out to J Smith18.
This one is a time skip one, Donatello will have a son in this and he will be 5 years old.
I own all the turtle tots in this fic.
Donatello couldn't be more proud, today he would be assisting his older brothers in teaching his son Jack ninja. He hoped that one day his son would walk in his shoes.
Though Donatello was not one to like violence he still didn't mind the work out it gave him from the many hours he would spend at the computer.
He was beginning to show his gifted son how to use a computer, mechanics and chemistry.
He stood on the side next to his father as they watched Leonardo go through the basic stances that Jack needed to know.
Deangelo and Trixie stood beside their fathers and watched as the boy who was three years younger then them begin his training.
Like his father Jack had a hard time learning the basic moves, he struggled to get his footing right and fell on his shell.
The two nine year old's laughed at their cousin as he was laying on the floor.
Splinter shouted at the two sternly.
"Enough, Deangelo, Trixie come here."
The two looked at each other before standing before their grandfather.
"You two were beginners once your selves, you will not disgrace your cousin by laughing at him, now ten back flips."
They walked off to do their punishment as Jack continued to try and get everything right.
After a while the adult turtles stood before their own father to begin their practice session.
Jack tried to copy his father's moves but kept falling.
Donatello looked over at his son and asked Splinter.
"May I be excused from practice? So to work with my son on his training?"
Splinter normally didn't let the turtles leave in the middle of practice but he would allow it this time.
Donatello lead his son out of the lair, Jack looked up at his father and asked.
"Where are we going dad?"
Donnie looked down at him and said.
"You will see, it is where I ran away to once when I was your age, my brothers were making fun of me because I had a hard time understanding the stances and moves."
They walked for about five minutes before coming to an empty part of an old station, Donatello pointed to a long ago fading outline on the floor.
"I trained my self, I came down here and gave my self privet lessons all the time, Splinter never really knew about this place until he found out that I had been going off on my own to train so he helped me set up this place so I can do it in the absence of my brothers. He would come along some times and we would spend some time together training."
Jack looked around the space, it was fairly good size and did not look as though it had been used in years.
Donnie took the broom that was by the wall and swept where the chalk was supposed to be, after the dust and dirt was cleared he drew with some chalk that was left there and put outlines of where to stand when doing basic moves.
Donatello turned to his son who was looking in an old subway car and said.
"Jack, come here."
Jack ran over to his father who pointed to the outline.
"Put your left foot here and your right here, now raise this arm and lower this one."
After about twenty minutes of practicing Donatello told him.
"You did well."
Jack smiled proudly up at his father and said.
"Thanks dad."
For the next several weeks Donatello and with the aid of Leonardo trained Jack together who was excelling at a wonderful rate.
When the time came to show Splinter, Jack was nervous, he stood before his grandfather and bowed with respect.
The entire family was there to watch as Jack preformed his first kata.
Trixie and Deangelo looked at each other then at Jack and Trixie said.
"Wow boy, you did awesome, how you learn that sa fast?"
He looked up at his taller cousin and said.
"I had good teachers."
He bowed respectfully to his father and uncle, Donatello told his son.
"I have a surprise for you."
Jack looked up curiously and asked.
"Really? What?"
"Come with me, I had your uncle Raph working on it while we have been off training."
He lead his son and his nephew along with his niece to his lab, the three children looked around then noticed a wall made of plaster was dividing the lab in half.
Jack looked up at his father and asked.
"My own lab?"
Donatello looked down and said.
"You like it? I wanted to let you have it for your birthday but that was too far off so I decided you worked hard learning that kata so I thought this would be an excellent reward."
Jack hugged his father and said.
"Thanks dad!"
The young boy ran to his new lab and looked around, he had almost everything his father did in the large part of the lab. He didn't have the dangerous chemicals that his father did, instead he had harmless chemicals that would not explode if mixed together. Or catch fire, hopefully...
What amazed Donatello was how much his son loved martial arts, he loved it almost as much as he loved science.
Considering Donatello loved science more then being a ninja.
Jack asked his father.
"What weapon will I have daddy?"
Donatello looked down at his son and told him.
"The weapon chooses you, the BO staff choose me a long time ago."
In the years that followed Donatello got closer to his son as he helped him in both fields of interests.
And like his father Jack wielded the BO staff as well...
