The scene plays out in front of him, just like he remembers, and Kou's breath stocks. He trembles- he doesn't know what to do. Instinctively he wants to reach out to Goro, his twin, to stop the tragedy that's about to unfold, but at the same time, Palnatoke whispers that he's still in Maruki's Palace, that surely, this will be used against him. Indecision eats away at him, but it doesn't look like he has to make a decision either way.

The scene starts melting, tearing at the seams, and Goro starts yelling- melting, screaming to shoot the button, and Kou-

Kou-

He screams, unholstering his gun and aiming at the quaking wall, willing his hands to still.

He fires-

-and the button shatters into pieces.

Bullseye.
