1. Introduction

Donatello was pretty sure that he was meeting his first true maniac.

From the way Raph's eyes lit up at seeing the older boy's getup, Don deduced that his hot headed brother had found a kindred spirit. Leo did not look as pleased; his silent contemplation of the youth was cautious at best.

Mikey flitted around their new acquaintance like a hummingbird, questioning and touching, pushing and poking. Somehow the annoyed look on the human's face at the youngest turtle's antics was very satisfying to Don.

In fact, their introduction to Casey Jones was met in characteristic fashion by each of the brothers with the exception of Donatello. He should have been curious and inquisitive, but instead Don was distrustful and wary.

Attempting to analyze his reactions to the stranger, Don had to admit that it was the way they were meeting the boy that had raised his hackles.

It wasn't just that Jones was a vigilante, or that he had an outspoken view on mutants, or that he was a bit crude. Don understood that he was what humans considered a 'bad boy'.

The problem was the look on April's face as she introduced Jones to them. How her eyes glittered when she'd told them he'd rescued her from Mutagen Man. That the entire time they were talking to Jones, April couldn't seem to stop staring at him.

Donatello had rescued April plenty of times and from much more dangerous situations than the ones she'd faced with Jones. Yet she'd never looked at Don with such a sickeningly gooey expression, at least not when she was fully conscious.

The word 'jealousy' popped into the genius' head and though he hated to think he was capable of such a distasteful emotion, it seemed the most apt under the circumstances.

Oddly enough, though April seemed pie-eyed around the youth, Jones didn't seem to return that attention. That should have made Don feel a little better about the situation, but it wasn't that easy to discard his suspicions.

While Don would have preferred to remain in the background and study this new state of affairs another peculiar thing was taking place. Jones seemed to be going out of his way to interact with the purple banded turtle.

Parked behind them sat the Shellraiser, driven by the Turtles when they came out of the tunnels to locate April. Stroking his hands along its sides, Jones had asked who their mechanic was, at which time Leo had proudly informed him that was Don. Since then the boy with the dirty face and gargantuan attitude couldn't seem to leave the genius alone.

It was a very odd state of affairs indeed.
