Water from 200 meters down

Before he could finish, the ground beneath him began to shake. He and Ruby both turned back to see a massive wall of water charging down the tunnel. Before either of them had a chance to run, the tunnel was completely flooded. The Doctor looked back over to see Percy slowly standing up, the wounds on his hand beginning to close. Finally the water pulled back, leaving everyone but Percy utterly soaked. “Uh…” Percy started. “Sorry about that.”

Ruby spit out a mouthful of water before shaking her hair to knock out any lose droplets that would come free. “Maybe warn us next time?” she said. Her expression was a rather interesting mix of annoyance and relief.

“If I was actually able to talk, I would have,” Percy responded as he hesitantly clenched and unclenched his hand. “Seriously, I think that hurt more than the river Styx.”

“I’m more curious about where the water came from,” the Doctor replied as he brushed some water out of his hair. “They said we’d be sealed in here, so where exactly did you draw it from?”

Percy shrugged in response. “Bellow us. Don’t think I could tell you much more than that. Maybe about two hundred feet down or so? But that’s just me guessing.”
