Josephine Polly Nyack

What initially appears to be a nun is a driver in a red sports card who Gen runs off a mountain road in a race. She tells him to call her Cotti but her full name is Josephine Polly Nyack. She is not an actual nun, but rather, stole a nun's uniform from the boarding school she attends.
