[Surprise registers on Kaito's expression at Aoko's tone. He recognizes the anger; it's the same anger he's seen in his own Aoko many, many times. It was actual anger, not the huffiness she had when he had teased her far too much.

He pushed himself upright again, his gaze never leaving Aoko's, and Conan was momentarily forgotten while he studied her expression]

A tracking device, yeah. [Though that was only part of it; he doesn't want to worry her with the other half. He keeps his answers calm, slow, and deliberate]

As for what I was arrested for... [he shakes his head] I was framed. Grand larceny, among other things. [Granted, he had actually committed the crimes, but he was far too good to actually be caught for them without someone planting evidence against him. Besides... no one gets the death penalty for stealing. That alone was enough proof about how corrupt the system was]

You've heard of Kaitou Kid, right?
