A blade stuck out of Mannequin’s upper arm, near the elbow joint.  The upper arm fired like a small rocket to stick in the wall, and for a second, there was slack in the chain.

Knives and then rockets? This Mad Dummy is doing things backwards.

Colin thrust the knife forward, came within inches of making contact with Mannequin’s chest before the chain reeled in and the metal links went rigid.

You tried.

The chain started to gradually reel in, and Mannequin started pulling his hand backward, toward the wall where the section of arm had stuck.

Ohh, so that’s why he did that. It’s acting like a winch.

Then, as if to taunt Colin, Mannequin dropped to a crouch, moved his face less than an inch from the blur that marked the edge of the blade’s effect.

Pfft.

AU where he accidentally gets a little too close. Whoops!
