I agree, its like your parents kicking you out, sending you to live with ''friends of the family'' (the ones you dont really know but do), then telling you that there moving too but you cant move back.
Its Nicoles home, its not just a house to her, its the place shes lived in for the past year or so, the place she probably feels safest, and feels closest to Roman.
She been through alot in such a short period of time, and shes been on the short end of the stick for alot of choices - Roman kicking her out, letting Aden not her move back in, been shipped off the Camp Summer Bay house for the imminent future - If i were here i'd be just a little annoyed too.
