Jack was ahead of the pack, twisting as she swam on occassion to ensure that the whole group was still together and no trouble had befallen anyone. She had asked to take charge, that meant that she was responsible for whatever happened. Jack would not have anyone harmed. The eighteen year old woman could not stand to have any more blood on her hands.
Something had changed. What happened to the clear, bright water? What happened to the schools of fish? Nothing moved, and that made it scarier really. Jack was not afraid, of course, she did not have a reason to be. Yet. She heard a clicking and stopped, treading water briefly, ears straining. She turned a complete circle. Nothing. Michael reached her and she jerked her head. They should continue.
Jack saw something shine out of the corner of her eye as she turned her head. She turned and saw Mari had lighted her wand. "No!" Jack said, a bubble pouring out of her mouth. She turned and sped over to the wand, covering the tip with her hands, shaking her head at Mari. Nessie was not the only thing here- the light would tell creatures where they were.
