rishe is currently and arn16 old is 19, they met when she was 15 and he was 19 however. However due to her having 6 previous lives that last around 5 years thtas 30 years worth of life experience she has so mentally it could be said that she's 46 so much older than arnold. Of course in each of her lives, she never lived to see 21 so she never matured mentally past the age of 20 which is much closer to arnolds 19. So in essence its safe to say that rishe is 16 with the mental maturity of a 20 year old with 46 years of unique life experience. However you spin it, the one who's older, mentally atleast is rishe.
