Redhawk Caldera Paul is dead.

Okay. So if he wasn't super keen on diving in to the water to get under the lodge, and they weren't going to destroy the lodge from the top, Reyes would have to come up with another method. Or bite the bullet and do something reckless — he wanted to impress his friend after all, and they could use the fatty meat from a beaver for their stockpile. 

Reyes frowned as he tried to think, but, there wasn't much coming to mind. A few minutes passed and then he huffed and shrugged. Guess it can't be helped. You stay out here and keep an eye out for any movement. I'm gonna try and scare it out. If.. anything is in there. Except that would also mean getting in to the water. It wasn't quite blizzard-level at this point in the timeline so the water wouldn't be too cold. 

As Reyes moved away from Towhee's side he attempted to find a route around to a spot where the dam met the water's edge. He almost pranced as he went, trying to avoid the gross feeling of wetness from the water or the mud, clenching his jaws as his toes soaked and then, gradually, his feet and ankles. Reyes probed at some spots and scratched at the surface of others, only stopping to listen between actions.

He thought he heard something moving and listened intently, but nothing major happened. Reyes then tried climbing on part of the muddy pile of wood, rising up as if he was about to mount it, scrambling, getting on a small ledge for a precarious amount of time, then losing his footing and leaping back down. The entire lodge shuddered—and something inside scrambled around, loud enough for his ears to catch it.

There is definitely something in there. Don't think it wants to come out.
