You look around a little nervously then wave to the girls, "Come with me." The girls, a little curious, follow you as all of you slosh out of the water and take a seat at one of the picnic tables in the park above the beach. You look around and see that the park is fairly empty as you turn back to the girls and prepare to explain what they saw and just what was going on.

Their reactions vary, Tiffany and Allyson appear...intrigued more than anything else, while Claire and Rebecca seem dumbfounded. Finally Amanda speaks up and says, "Prove it."
But how now?
