It seemed like Arisa found a way out of her situation that Geb had put her into. That was fine, after all, he could do other plans that he had ideas for.
Because her fist was no longer blocking the way, Geb now had a way to attack. Or, well, an additional way. Letting his arm be grabbed by her, Geb at the same time would do a low sweep towards the woman's legs with his right leg. Aiming at her knees, due to the fact the woman had been pivoting it probably would have been even easier to tip her over onto the ground. His strength would most likely have no problem with this, so he went forward with the sweep.
Should she have been knocked on the ground, Geb still would be in her grasp. However, he could use this to his advantage, having lots of possible attacks he could use. Should she fall on the ground, Geb would most likely let himself be taken down with her (or just go down on his own, should she have let go) and use his left knee, the one that did not sweep, to pierce downwards onto her liver, on the left side of her body, with all of his strength.
Should the sweep somehow be avoided, in order to get out of his current situation Geb would have to use his left leg and kick the woman with a circular kick in a counter-clockwise motion upwards in order to reach her hips, trying to knock her off balance. But again, only should the sweep be avoided would this turn of events happen in the timeline that was true.
