Rather than quell her rebellious thoughts, her success simply fueled it. She applied to the Chicago Dojo of the ACW Academy and was accepted as a provisional admittee. A quick learner, she took to the training immediately. Standing 5' 10" and weighing 131 lbs., she had the size and range to keep her opponents at bay and was able to use her reach advantage to grapple with her adversaries. More noteworthy was her ability to use her long legs to deliver kicks to various parts of opponents bodies. Her biggest weakness was her unwavering belief in her own superiority. "Because she was a fast learner, and very skilled physically, she believed that once she had "perfected" a maneuver, she could not be stopped," said trainer Tanako X. "She argued with a number of the trainers at the Dojo, refusing to continue practice on elements that she felt she was already accomplished in." This led to a well-publicized confrontation between Cartier and Tanako X. "I told her that she must conform to the regimen we set out in the Dojo, or she must leave. I saw that she wasn't trying be disrespectful, but really just believed she knew better. I took her onto the mat in front of the other student and trainers and told her she could try as many maneuvers or attacks as she wanted and that I would deliver one kick and immobilize her." After evading a flurry of kicks and punches by Cartier, X delivered a roundhouse kick to her back that knocked the wind out of her and left her helpless. "I hoped that it would humble her and show her that she still needed to learn a lot. Unfortunately, it did not." Cartier immediately left the Dojo and filed a lawsuit against X and ACW. The lawsuit was dismissed before it went to trial.
