Nanites

Even though he was the one that invented them, Thom was still pretty impressed by his nanite technology. They were able to cover his body and over the course of an hour, completely change his DNA. He was now an exact copy of Ami. The nanites even managed to modify his clothes. He couldn’t help but stare at his reflection; he’d probably be able to fool anyone...except for Ami herself. He decided it was probably best to avoid her as the nanites recharged. He didn’t want to have to explain his new technology to anyone until he had the chance to have a little more fun with it. And now that he was for all purposes Ami, he decided he could have his first bit of fun.
