Rubina again accused Jasmin of being someone that she is not (she was clearly pointing to how Jasmin changed after Aly's entry). I think it was the feedback that she got from Aly that made her rethink her game and change her strategy...that does not make her fake. She had a valid reason to put her game first because the turn of events in the initial weeks (the doll task or the WKW where she was called Rubina's puppet) made her believe no one had her back and she was just being used to further their own games.
