So, she claims that the girl (15) consented when she (Amanda) was 17 to some unspecified sexual molestation encounter. Some time after this happened, Amanda was being ween'd at IRL on her bus, and (15) she joined in. Amanda "beat the shit out of her" / "beat her head in" to the point the girl received a concussion, but Amanda did not draw blood.
Some years later, when Amanda was married to Larry, she (formerly 15) found Amanda on Facebook, recognized her, but could not place where she had met her. Amanda lied, at the time, but later came forward with who she was/what she did to this girl. Since then, Amanda has tried to contact her, and (formerly 15) has never responded.
We also learn that SOMETHING was wrong with Paris.
