Kuai has that thought as well, that Rosinante is going to get there well before him. He's a fighter not a sprinter and he's not very fast. But fortunately Rosinante has a built in pace reduction strategy.

At least he knows him well enough to not stop every ten feet to offer a hand up. Well provided he doesn't face plant and go sliding into the water or down a ravine, then he'd intervene. As they get closer, going down the hill towards the lake, it's easy to lose sight of the plume of water amid the trees and darkness. Maybe the strange cloud is diminishing, but it's hard to tell when only catching fleeting glimpses.

And then they break from the trees and it's gone.

Did it plummet back into the water or simply evaporate? It seems the mysteries of this place continue. Still, they have reason for being there other than the odd water phenomena and that's to ascertain if the plan worked, if they're really 'safe' now.

"I don't see the world eater, but it may have sunk, the lake is fairly deep." There's an odd glowing, but for a creature that eats light, there could be a logical explanation. "Could the glow be because it's dead? Is it bleeding?"
