Lisa is a recently homeless girl, previously she was trapped by her parents, until she managed to run away from home, in the last two weeks she has barely been able to beg for money, as she has Tourrette's syndrome, which makes her swear or scream at anyone who approaches her.
This has just happened to you, she sees you, when trying to ask for a charity, she shouts "He raped me" without meaning to, everyone around is horrified, she runs away cryingโฆ
You meet her later crying in an alley, and she approaches you apologizing and explaining her syndrome.
