Sonia started to step forward towards her new twin when her stomach grumbled violently, feeling almost like it was expanding. The sensation spread and she stumbled into the stall as something shifted and descended under her skirt, foreign sensations spiraling out through the rest of her body. Jon watched in awe as the inverse of his own transformation happened in front of him, skin paling as her body shifted. Sonia's bodyweight redistributed, the weight of her chest and rear redistributing to her arms and stomach, making her a little flabby just as Jon had been. Jon ran his new hand up his arm, feeling the subtle muscle tone there and realizing how much more fit he was now.
Acting almost on instinct, Jon spoke, "Take off your clothes." Despite being a native English speaker, his new vocal cords recreated Sonia's accent perfectly. "What!?" Sonia cried, more focused on the somewhat painful transformation wracking her body. "Take off your clothes, you don't want to ruin them." Jon commanded while stepping forward. He unfastened the buckle of skirt and shimmied it down her legs, before beginning to guide her into shrugging off the red blazer that still bore the Jon Gibson name tag. With his help, they managed to get Sonia out of her outfit before her transformation completed, Jon quickly plucking her earrings from her ear lobes before the piercings sealed up. Jon set Sonia's clothes aside while she fell against the far wall, the transformation reached her head and began shifting it into a copy of the one he'd worn that morning.
Jon pulled his tee shirt off and was about to toss it on the pile before he spotted the Sonia Esposito name tag on it. He slid new long nail under the tag and peeled it off the shirt, swapping it with the one on Sonia's discarded blazer, so at least their clothes were correctly labeled. Finally Sonia's transformation finished and the two stood there panting, trying to comprehend what had happened to them.
"What, what the hell happened!?" Sonia demanded, her new blue eyes bugging wildly. Jon pursed his lips, thinking rapidly before saying. "I don't know, but we don't have time to figure it out now. You're late for third period and I can't be found in the boy's room or we'll be in bigger trouble." Jon reached for and grabbed Sonia's discarded clothes, "We need to get through the day without anyone knowing what happened, comprende?"
