Come on, it's not her fault. First of all no one has ruined the whole mood. Irma, Anna and Ilona were very close so it's only natural that when a fourth person is thrown into it the dynamics change. I think she blended in quite well, all things considered, and they all get along fine. Secondly, if anyone is to be blamed it's RLC for having too many girls at the same time in the apartment, not the girl who most likely didn't know exactly what it would be like. Personally I don't mind, it gives the place something extra that the other apartments don't have.
