"A lot of black, nasty water," Rocket told him, point blank and blunt. He was seriously debating whether or not to tell him about the shelter- it'd be a great place for a poor sack of skin like him to hang out, if not for the Things that were surrounding it. Even Rocket considered blowing up the only entrance to make sure whatever was there didn't get into their little maze.

"It's a sewer- carved out walls, long as hell. Leaches, too. And there's a lot of shit under the water..." He didn't feel the need to mention much of that shit was left by him. "The end of it leads to this old bunker. It has water and a few places to sleep, but I really wouldn't suggest the trip."
