I'm not saying that urvashi is a saint, i'm sure she will create a problem in future. But as of now, all she is showing is concern for her sis, any sister would feel the way she does. But its Tara who is reacting the wrong way. She needn't behave the way she is. Urvashi never told her to do that. Its Tara's own doing!!!!!!!!! So why portray her bad already???
Even if the director wants to show Saloni has a person, who never does any wrong (which is getting annoying), its on us viewers to look at every character from a diff angle. For eg. Kaveri and Kaki are bad from any point of view. But i don't think we can say the same for urvashi (atleast not right now)
