Nice addition to the story. I was kinda hoping the sprinkler system would dose them again but eh, can't have everything we want can we?
I'm kinda surprised they(the Emergency crew guys ) wouldn't put two and two together about the sprinkler system sooner though. Especially after the one girl already figured out it was about the water.
Keep up with the great work on the story. Everyone deserves a vacation every now and again but I hope we get more soon.
