"Could be," he says, then rocks back from his crouch into a seated position (with a bit of a teeter backward and collapse before righting himself on the gravel). He glances over at Will to try and gauge how he's feeling now, for he heard about the thing that slipped past and attacked the two down below and has been trying not to feel too guilty. The defenders above did their best; nobody would claim otherwise.

Mostly it's a relief to see Will up and walking. Had he not heard from him in a little while, he had planned to go over and check on him, maybe make some coffee. He knows Will doesn't sleep much at all if he can help it, and so it was a tossup between whether he'd want company or not. But now he doesn't need to wonder, and so he leans ever so slightly toward Will. With Will standing and Rosinante seated, his head contacts Will's shoulder - gently, though. Just a touch, since he's not entirely sure of the full extent of Will's injuries.

"I've heard about things like that," he continues. "Some little animal in the water that glows in the waves, right? Never seen it myself. I thought maybe... maybe it was the light that spilled out of that thing out there. Proof it's dead."

After all, it ate light, right? Is that a dumb assumption? If you cut open a monstrous fish, you find out what it last ate, so do World Eaters work the same?
