Rover sat down in front of the chrnonivac. He then looked at the sleeping Edwin in his bed and grinned.
First of all, Rover froze the countdown and changed the setting, so it won't change back automatically after some hours. Then he figured out, how to get a life for himself. He wanted to experience the feeling of being human, with family and friends. Since he barely knew the human world, he couldn't think about a complete new life for himself and he didn't want to explain to others, who he actually was or where he was from. So his idea was to change everyones perception of him and Edwin, so that everyone would think about him as Edwin and the actually Edwin as the dog Rover. They would change places for some time. That was the easiest way. What he was about to do wasn't meant to be evil, he just wanted to stay the way he was now. And he knows how good this family treats dogs, so Edwin would be well. At least he assumed he would ... there was a little difference: Rover didn't care about being a dog as long as he was one, Edwin would, maybe.
He hitted some keys and typed in the new settings. He didn't want to shock his former master with the transformation into a dog, neither did he change Edwins memories, not yet. Secretly he actually wished, that Edwin wouldn't mind the switch.
