This time, the hallucination works for him instead of against — he takes a gulp of breath, halfway towards hyperventilating, and the smell of antiseptic fills his nose and lungs, strong and sharp. It's jarring enough to push the part of him that's been fighting for control over the hallucination to the forefront, and his grip on Cora's arm tightens.

"Cora-san —" There's surprise there, eyes wide, like he can't quite believe what he's seeing.

Then Law blinks, gaze focusing, slowly.

"So... that's what happened. Shit," he mutters, because the world eater must have trapped him in a hallucination like the green eyes, leaving the real him unable to defend himself. Promptly, uncaring of the way his wound feels like it's on fire, he grabs the antiseptic and just pours it on the jagged edge of flesh and blood.

Hissing, he lets go of Cora's wrist and instead motions with it.

"Kikoku," is all he says, and while he could probably shambles it to him, he's trying to conserve energy here.
