Sarah heard the teacher call her name, and she panicked. How was she supposed to ... wait, what is she doing?? She sensed the water before she saw it. Of course. 
Sarah let out a deep sigh and calmed herself down. She should have known the teachers would take care of this. Hadn't she just seen just how far they would go to make sure the students could fight safely and test their abilities to the fullest?

Suddenly, Sarah smiled. She'd get to test the extent of her powers without having to worry about hurting anyone. Feeling the call of the open water, she jumped up from her seat and practically bolted down to the arena. She was still vaguely aware of the water in the pipes behind the walls, but the call of the open water was so much stronger! She took her place in her corner of the arena, took off her shoes stepped into one of the puddles. She laughed out loud, turned to Cole and said [color=92278f] "My name is Sarah, pleased to meet you. This is going to be fun!" [/color] Suddenly serious, Sarah turned her attention to one of the puddles. The water stirred and bubbled until it was nice and muddy. Content with the results, she smiled again, made the muddy water rise and dumped the lot of it unceremoniously on Cole, drenching him. 
Giggling at the result, she waited for the muddy, sopping boy to make his first move.

(edited when I realised she actually got up twice, lol)
