Legal Question in Landlord & Tenant Law in Kentucky

I'm confused by the facts here. She "got out of the contract," but your parents are still paying rent on her behalf?

If she is not obligated to pay rent to the landlord under the lease agreement, then she isn't obligated to pay rent to anyone, unless she has some sort of other agreement with the roommates. However, if she is still on the lease, then she has to fulfill her obligations under the lease, even if she moves out early. If she doesn't pay, her roommates will likely have to pay for her, and then could come after her for the money,
