This story is based in the 2007 Movie Universe with a bit of the comic books thrown in for fun. In the timeline, this story comes after the movie. Everything is right again in the world but there is still some tension in the family unit. (Of course there's tension… fanfiction wouldn't exist unless there was always the possibility of tension.. who wants to read about the turtles having a nice relaxed vacation in Cyprus?)

I really enjoyed the 2007 movie and as it was very Leo and Raph centric, I thought that if there was ever a sequel – it would be about Donny and Mikey. So here is my idea.

Disclaimer: I do not own the turtles.

It was just another Friday night. The turtles had been out scouting the rooftops of New York, as usual, making sure everything was as it should be.

Just another night where he and his brothers bounced around, sparred and enjoyed the night air. Donatello loved being above ground with his brothers. It did annoy him, however, how they seemed to be more naturally athletic than him. It wouldn't have mattered if they were humans.. but they were Teenage Mutant Ninja turtles and 'Ninja' was what they did. But he never complained. It was just one of those things. He knew better than anyone how genetics worked, especially in animals. He was the literal 'runt of their litter.'

"Okay everyone, go to the equally distanced starting points we agreed on and we'll see who can make it back here first," ordered Leonardo in his 'leader' voice.

"How are we going to know when to start, oh fearless one?" sneered Raphael in his 'you are not as smart as you think you are' voice. Leonardo and Raphael had a much better relationship these days but as Mikey liked to say 'you can take the turtle out of the fight, but you can't take the fight out of the turtle.' The two eldest brothers still bickered on a regular basis but it was brotherly and ..well… normal. Donny even thought that it helped bring out the best in the two turtles. After all, they were perfect opposites of each other, like ying and yang. What one lacked, the other made up for.

"I will give a signal," explained Leonardo. "You'll know it when you hear it."

"No, that's not fair!" whined Michelangelo. "Raph will start early, he's a cheater."

"Are you kidding me!" burst Raph in disgust. "I think we all know who the cheater is in this team."

Michelangelo feigned hurt at this remark but Donny knew as well as the other brothers that Mikey had less respect for sportsmanship than anyone on the planet.

"Don't worry," laughed Donny. "I installed a GPS tracker on everyone's belt buckle so I'll know exactly who cheats and who doesn't."

"Really?" asked an amazed Michelangelo poking suspiciously at the 'M' buckle in question.

"Oh yes, it uses heat signatures and vital signs in relationship to the environment to detect exactly where you go within the city limits," continued Donatello, trying to use as much technical jargon in the sentence as possible.

All Mikey could respond with was a wide-eyed "Woooah," while his three older brothers laughed quietly under their breath. They knew Don had just made it up to keep everyone happy. That was just one of his many roles – peacekeeper.

"Alright fellas," let's get this started. The turtles dissolved into the shadows to find their starting marks. As they were waiting for Leonardo's signal, it started to rain.

"Oh great," muttered Donatello to himself. He was very much an indoors turtle when it came to physical health. If he could live inside a bubble he would. He hated how easily his body caught sicknesses. And this challenge was going to be tough enough as it was. Nevertheless, Donny planned to give it his all.

Suddenly, the sound of a Eurasian Eagle-Owl whistled through the wet, night air.

'That had to be the signal,' thought Donny. 'They don't live in the Americas… wait a second.. when did Leo become an expert on owls?' Donny realised he was wasting time and launched himself from the satellite dish he had been sitting in. He bounced across the skyline, using his bo staff to make the extra-long jumps. He thought he saw another shape in the distance but he ignored it. He used window ledges, cables and sometimes loose bricks to descend the buildings until finally; he made it back to the meeting point.

To Donatello's dismay, all his brothers were already there. He tried to hide his disappointment. It happened so often he thought he'd be used to it by now. But he never was, and it was always awkward.

"Glad you could join us Brainiac," laughed Raph. "Did you stop to admire someone's TV?" Donatello laughed good-naturedly on the outside but inside felt a sense of shame.

"Don't worry Donny," reassured Leo, you were only a few seconds behind and I'm sure you had the hardest route. Leo patted him on the shell which in many ways made it worse. Donatello felt himself tense up in awkwardness and desperately searched for a way to change the subject.

His body decided to do it for him when he suddenly let out a mighty sneeze.

"It's raining," Donny said. "We should head back."

"Wow, you really are a genius," laughed Mikey sarcastically, leading everyone back to the lair.
