Mark pointed the device at Jennifer and pushed the “Physical Fusion” button.
Suddenly he found himself standing in the bathroom looking into the mirror at a reflection that seemed a composite image of himself and his older sister Jennifer, merged together into a single person. He looked a bit older than himself, but definitely younger than Jennifer had been. He had his own, darker colored hair instead of Jennifer's blonde curls... but it was styled the same as Jennifer's had been. And he was now wearing slightly smaller versions of all her clothes: a tight, pink top, a short gray skirt, and a pair of pink and silver ballet flats. In one hand, he held an open tube of lipstick, baby pink in color. In the other hand he was pleased to see the futuristic reality controller.
“Mary!” called his mother's voice in the distance. “Hurry up, or you're going to be late for school!”
Without realizing what he was doing, Mark involuntarily huffed a dramatic sigh and shouted back to his mom: “I'm going, like, as fast as I can! Gimme five more minutes to finish my makeup, sheesh!”
As soon as he spoke, he realized he had, without even thinking, acted just the way Jennifer would have in this situation. Somehow, this little machine had changed he and Jennifer into a new, amalgam of their two former selves.
