Kyle's mind was racing with more and more possibilities about what he could do with this device. He could do whatever he wanted now. He thought about changing Alex back but decided against it. The new Alex was much nicer on the eyes compared to the real one. As the show ended, the new Alex turned off the tv and started to take a nap.
Kyle saw his opportunity and snuck up on his room. He found that the door wasn't actually fully closed, so that if Kyle wanted, he could lean into the room undetected. He wasn't about peeping so this normally wouldn't appeal to him, but with the device, Kyle could only think of fun swaps he could pull.
He decided Brook would be the perfect subject. She was a cute Italian with curly black hair and nice tits, and he figured it'd be fun to see her in other lives. Kyle looked around the suite and weighed his options. He could swap Brook with the new Alex. He'd be able to hang with Brook thinking she's Alex and it'd be funny to see some older Asian woman act as Brook and as Ty's girlfriend. There was the suite gold fish Bubbles which was sitting on the counter. Switching the life roles of a fish and a person could be really fun. Then he also thought about an object. Who knows what could happen if he tried to switch Brook with clothing, or a couch, or food.
Finally, he could always swap Brook with a neighbor. They had quite a few people around that Kyle would love to see Brook in the life of. There were just too many options. Eventually, Kyle made his decision.
