Being the oldest in the family meant you had to look after your younger brothers. You essentially had to pick up where your father Splinter left off when he stopped being a sensei/mentor or father. Like, for example, you had to deal with all of the emotional baggage that having four brothers who butt heads, constantly, comes with. You were basically like a second parent for your younger brothers, Raph, Leo, Donnie and Mikey. You made sure the lair was clean, so your brothers could have more free time.

Not that the four boy turtles knew that. You woke up earlier than even Splinter just to clean the lair and boil the kettle, all before Splinter or Leo woke up first. You had more ninja training than the four brothers, and that really came in handy when you were cleaning and trying to be quiet. It was your way of showing you care, even if the others didn't realise.

Leo thought it was Splinter cleaning the lair. Raph, Donnie and Mikey all thought it was either Leo or Splinter who cleaned the lair. Splinter has a feeling it is you, but he didn't bother to ask. You were often back asleep by the time he woke up, and you were often the second-to-last one to wake up out of the siblings. So, they all thought you were just being lazy.

However, one day, you overheard the four turtle mutant brothers talking. "Hey. Do you bros know why the lair is usually so clean?" Mikey asks as he sits upside down on the lair's sofa, comic book in his hands. "Doesn't Leo or Splinter clean the place?" Raph asks the pinball machine, his pet turtle Spike resting on his shoulders. "I don't clean it." Leo objected, having walked into the communal area/living room. "And, I'm pretty sure Master Splinter wants us to clean up after ourselves." The blue-wearing brother added as he sat down next to Mikey. "Then who cleans the lair?" The youngest brother, Mikey, asked with a puzzled voice.
