He always knew they were different.

His earliest recollections were of his father's stories of when he was someone else and of the picture placed on the shelf in the dojo. It has hard for a young boy to understand that his father used to look so different. In the picture, his sensei appeared like the people on TV. He never saw anyone like himself or his brothers.

It seemed to bother him more than his brothers. They seemed content to live in their world, below the people their father said would never understand them.

But his mind was restless, thinking. What made them so different?

As he got older, the questions became more intricate, like an elaborate tapestry with no definable beginning. He thirsted for knowledge on human and turtle alike, comparing the attributes of each to themselves, balancing all of his findings on the scales of his mind. Just knowing they were different was not enough.

Just how different were they? Just because they acted like humans, how human were they? Because they still looked like turtles and were born as turtles, how "turtle" were they?

He never knew where to draw the line. And being a scientist by nature, he lived in the black and the white. The grey was the realm of theory, of uncertain postulations, areas he instinctively needed to bring out of the haze and into the light of fact. However, his family was unique and with such a one of a kind sample population, he feared he would never reach a definitive conclusion.

Little did he know that at the age of fifteen years, the answers would come to him in the most unexpected way: in the form of a human girl named April O'Neil.

A/N: Very short intro chapter, it's more of a prologue, setting the scene.
