@BloodySorcerer Her only response to that later conversation is "...Seriously...", i.e. just repeating what she was told. The "Right" came from Ayame (notice the bubble-arrow pointing the
other way). The girl is an idiot who believes rape is a form of love just because she was told so. We have no actual evidence of her having changed at all, just that she is upset (facial expression). Her being upset in the first place was because she's jealous of Ayame changing her own image.
Regardless, the fact that Ayame had to
stop her by force and sit her down to talk, means she didn't stop on her own. If it's like you said, Ayame talking to her made her realize what she did and stop, Ayame is
still the one who
stopped her. She didn't realize how horribly she was acting on her own, someone else had to point it out to her. If she had stopped the rape
before Ayame came along, yeah I agree, she would have stopped on her own. She
didn't.
