The Hindu code of Manu was very clear in these matters. If the woman's father is not around, the duty of controlling her base desires falls to the closest male member of her family, in this case Raj. The code also states that if she disobeys, she will be reborn in the womb of a jackal and tormented by diseases. If true, that seems like an awfully large gamble, given that the prize is Leonard.
