Thank you for responding. I have watched the video, and yes, I get to this point, press the square button, and am still grabbed by the throat and thrown to the ground, killed in one sweeping succinct movement, then get her attitude.
I have gotten to this point multiple times, repeat the motion, as well as try other things, and still cannot defeat her. It is very frustrating!
What am I doing wrong? Or is it a glitch?
Thank you for your help! I removed the disk and after reinserting it and thus restarting the game, I was able to defeat her. It was far easier than previous iterations of the fight, and I am wondering if the glitch was the gameplay mode, i.e. this previous fights I had engaged in weren't playing in the Story Mode but another, far harder mode. The Sister spoke a whole lot less during this fight, and the damage I was able to inflict on her made the fight go quickly. The whole fight lasted maybe two minutes, whereas before the fights were lasting, when I was able to get to the third and final stage of the fight, in excess of three minutes.
I finally beat her and am able to move on!
