"Let's not provo-" he's speaking to Katniss and stops dead, as one of these things - too slick and wiggly to be a shark but shaped similarly, longer - bobs out of the water with disturbing, gravity-defying ease, heading right up to the bubble of light that Rodolphus had cast.

".. I don't think they did that, but I don't think it'd matter, and yes, I think they could, if they were properly motivated." He's still watching the things in the water as he speaks - there's more visible now, all gathered about the light. The keening, screaming sound is increasing. "Send that thing away from the boat, if they're so fond of it."

A creature nearest to the side of the boat, still within the spill of light, looks up at them with bizarrely intelligent eyes - curious.

Not a friendly curious.
