Mr. White laughed as he heard Mary’s question “you can never take the collars off” he said calmly “as you may have guessed they are tracking devices, and they carry a charge within them that is strong enough to kill a man…or a woman. They are completely water proof, fire proof, ect ect. The only way one will shock you is if you get it into your head to try and take it off.” He looked at each one of them in turn before continuing “I’d highly suggest that you don’t tamper with them…it would be a shame to leave a mess for the others to clean up”<br/><br/><br/>“Now then” he said “It’s time that we got you on the island, normally I’d simply let my guests take a speedboat, but since I’m not an idiot you’ll all have to swim. You have exactly 10 seconds to be on your way. Before my associates with the very big guns decide they want some target practice”<br/><br/><br/>Mr. White wasn't worried about having them swim, the distance wasn't even a hundred yards, and the waves were anything but rough. If they were able to swim, they'd be able to swim to shore.
