Imagine that when Jasmin was invited to RLC, she was told that she would be living in a house with other girls, and cameras everywhere. She should try to act naturally although there would be bonuses for putting on a show. What she might not have been told was that all the viewers expect to see the girls playing lesbian games and dancing naked to all hours of the morning! Jasmin hasn't changed one bit since her first day, this is just her natural personality, and she sees no reason to change it. And as I've said before, I like that about her, it indicates strength of character.
I'm pretty sure that Michelle has been brought in and told that her job is to bring sex and excitement. If there are girls in the house who have different mandates then there are bound to be clashes
