Kotetsu isn't in any fit state to notice. He's about at his limit on horror. He might notice later, and that will just make it even harder to fight the urge to curl up somewhere and drink himself senseless. Maybe if he clears out the cellar under the kitchen, he'll be able to sleep without remembering this and stop it, damn it, stop it.

He blinks his vision clear, jolted back to life by Frisk's movement. He looks at them, looks at the blanket...and then immediately looks away. As much to get some distance as anything else, he gets to his feet, and when he takes a deep breath it doesn't taste quite as much like blood. His hands are clenched tight at his sides, but it doesn't stop them shaking, even the one that's now clenched tightly around the slick handle of the shovel.

"I can beat up anyone who would do this to a child." Giant crocodiles, evil ghosts, robots, anyone, anyone. Let him find whoever did this and punish them. Let there be justice for this. "Tell me who it was, Frisk. I won't let them get away with this."
