Jon watched the camera's screen, his face suddenly changed to being more feminine, while also heavily made up, his hair had gotten longer and turned black, while Zoe's was Wavy, his was straight, he wore a dark shade of Red lipstick and had shadowy eyeshadow.
Zoe cracked up, "That's a good look for you Jon, more like me. I'd be happy to loan you some of my makeup"
"Yeah real funny, I guess its like a clone filter? it mirrors the person on the left or something and matches it on the first?" Jon closed his phone and headed back to his room, but as he passed the hallway mirror, he could've sworn his hair looked darker... and his lips looked just a shade darker.
