Carmella asked Harold and Lou had they see her bra (lol - that bit was amusing!) and then she saw Lolly wearing it. The next day (well episode, i think) Dylan came to talk to Carmella about Will but Lolly came in so they went to the bedroom... Lou and Harold then came in and Lolly implied that they were having sex and she saw, so Lou has demanded that Carmella moves out. She is doing so, but has told Harold that she doesn't trust her at all, she's lying and think she has issues!
She's just causing trouble and trying to stir things up - rubbish at it though as pretty much everyone doesn't trust her!
