No matter how Arshi is viewed by other housemates.... she always respected Rubina until today's episode.... but the way she shouted at her.... and told her to shut up like a dictator and called her gandh.... she's the one who started this rivalry....not Arshi.
Now Arshi has full right to go out on her. Even in the next episode Rubina would do her body shaming by making that duck lips comment on her. So she's the one who is picking fights with Arshi. Not the other way round like Rubina fans are claiming.
