Jeff saw that the package had a scan feature that would let you setup pocket realities... with the main limitation being that you had to scan everything into the chronivac device, but once something was scanned in you could use it in a pocket reality. Whether it be a person, an animal, an object, or an entire area it would first have to be scanned. So Jeff took a quick walk around the house scanning his whole house and everyone in it, and went back to his room to test out the package by creating a pocket reality of his house in his closet. Jeff then walked in and there was his house that was populated with his family at home but Jeff could feel the Chronivac's powers at his finger tips able to be used at will on ANYTHING within the simulation... made some sense this was a simulation within the Chronivac in a sense so, it should be able to change anything inside. He did a few tests first modifying his body to be younger, then a girl, then older, and then back to being a guy. He had a little fun spawning two extra copies of his mom and seeing them freak out before exiting and ending the simulation.
This felt right for Jeff... He would feel a little too... nervous was the right word, nervous to actually try anything out in the real world with the chronivac even with awareness settings... Being able to try things in a simulated world that he would normally not be able to have the nerve to do in real life was just what the doctor ordered for his self confidence, and possibly his libido. He'd just need to scan some people and areas first.
