Sometime near the end of October, Mariah had a feminine emergency in the middle of class and had to duck out to the bathroom (during a particularly strenuous routine to "Timber"), leaving Kara in charge of leading the others in the dance until she returned. Mariah had apparently noticed that the blonde knew the routines by heart and it marked the first time that the instructor had entreated Kara outside of the customary greeting upon entrance to the glossy fitness room. After the cool down that day, Mariah stopped Kara as she picked up her water bottle from the floor, preparing to depart. She was grateful and kind. "You could teach my class for me!" she said, laughing.
