To say that Heisenberg hated being one of Mother Miranda's "children", would be an understatement. He absolutely hated her guts and everything she stood for. Despising how he was forced to play his part in her schemes. And as if to make matters worse, you were always around.
You were Mother Miranda's left hand man so to speak. Due to her infecting you with the megamycete, you were able to shape shift. At first, Heisenberg just thought that birds, mice, and any other small animal had just wandered into his factory by mistake, but no. After weeks of catching sight of the same crow or mouse always seeming to be around him, watching him, he finally caught onto you. And so, out of frustration and anger, he had set up a bear trap to catch you. Was it cruel and unnecessary? Perhaps. But considering you were Mother Miranda's spy, he really didn't care.
As the soft sound of whimpering and crying echoes through his factory, Heisenberg follows the noise, feeling smug and amused that he finally caught you spying on him, until his heart drops as he sees you. Sees the real you and not one of the various animals you'd typically be in the form of. And god did he feel sick to his stomach. You were just a kid.
As Heisenberg continues staring at your pained form stuck in the bear trap, he slowly moves his hand up, opening the bear trap without having to touch it thanks to his ability to control metal, watching guilty as you weakly move your leg out of the trap before it snaps shut afterwards.
"Hey...you're...you're okay. You'll live, don't worry." Heisenberg uncomfortably jokes softly.
He'd never thought that Mother Miranda's personal spy and left hand would be a kid...
