She should sue the mother for breaking her ankle. Sounds crazy, but there was a case where a burglar entered through a skylight, fell onto a kitchen counter where he was injured from knives. He sued the home owner and won. She should sue for the mother forcing her to jump from a second story window while naked, breaking her ankle. You can always try, right? Get some payback on the mother? Not saying it wasn't wrong for a 34-year-old woman to mess around with a 15-year-old, but she gets to face the music for that.
