I think Blair reports back to Jasmin what is going on and what the other girls are doing, she was just there telling something to Jas and then back to the kitchen.
Maybe would be better for Jasmin to leave if she dont get things solved with Rose, can't be fun for her to live in that house always having to avoid the other.
Belle and Rose comes for real but only when they do it by themselves, meaning that show they put on before wasnt real orgasm, even though it was nice to see :)
