Knowing he needed to find a good test subject, Alex decided to look for his sister Emma. He knew she would be the perfect target. Because Emma was his sister, he would easily be able to observe how any swaps affected her without arousing too much suspension, and she could be difficult at times, so he wouldn't feel bad messing with her.

Either body swap option could also be interesting, but no clear idea for a swapping partner immediately jumped out at him. As for the final option, body and life swap... Well, the only option there was to swap her with himself.
After giving it a bit more thought, Alex had at least decided on what button to use. "Here goes nothing," he muttered to himself. He pointed the remote at Emma and pressed the...
