When he didn't release at the kick, she had a feeling she knew where he was going next-- after all, if you had the limb of an opponent in hand, you might as well use it against them.
As he started to fall back, Dinah scrambled forward and, after a miss the first time, finally managed to get both hands clasped around the back of his neck to keep him from falling all the way back. Had he been wearing his uwagi, she would have grabbed the collar instead, but without it, she held onto his neck instead. While she was grabbing for his neck, she flexed her foot, catching her toes up just under his shoulder, right behind his armpit and held, stalling for time to keep him from landing completely down on his back and wrecking the ligaments in her foot wrong-- painfully wrong. With her left leg caught between either of his, Dinah wrenched her left arm down, squeezing her hand between her leg and his to grasp the upper arm of her own gi for support. At the last second, she released his neck with her remaining hand and locked it down on top of his thigh and throwing her free right leg up over as well, her foot near his hip. She leaned back slightly, going for a knee bar.
