"Mmmmph! Mmmmph! Mikey tried to cry out, but the gag in his mouth prevented him. Of course, his arms and legs weren't any better off, being bound to the many thick pipes that ran above the main room of the turtles' underground lair.
In the main room down below, his brother watched silently, secretly enjoying the spectacle. He would let Mikey down again - once he was sure he'd learned his lesson. He studied the knots binding Mikey's wrists and ankles to the pipes. Hmm. Tight enough that he won't fall. And if he does, he'll just land in the pool below. Just enough to make sure he doesn't fool with them again. He looked up at the sound of a door opening - or, rather, the sound of a door being kicked open.
"Grrr! Where is that knuck..." Raph stopped short, blinking at the sight of his baby brother hanging tied to the ceiling. His eyes widened and he lowered his gaze to the brother standing below.
"How'd he?" Raph asked, pointing to Mikey with a sai.
Leo crossed his arms, his eyes still on their youngest brother. "You remember about a week ago, Raph, when he got hold of my katana and decided to paint them rainbow colors with," he sighed, "pretty pink flowers?"
Raph nodded dumbly.
Leo smirked and sat down on the couch. "Patience is a virtue, Raph."
Raph flipped over the rails of the staircase from the upper level and sat next to him.
"And so is the element of surprise," Leo finished.
Note: And that's how Mikey learned not to mess with Leo's blades. :) I got this little idea from watching Mikey's FoxBox bio vid on YouTube. I noticed that he messed around with Raph and Donnie's weapons, but not Leo's. And now we know why. (Though, I did try to show that Leo made sure Mikey wouldn't get hurt if something went wrong.)
