In this track as a whole (not taking episodes one at a time), Raghav has messed up just as badly as Pallavi has. But because of the way the show is written, we're made to sympathize with him because we get so much insight into what he's feeling. Thus the frustration cancels out a bit.
I'm okay with Raghav and Amma being pissed off at her. But I agree with that poster ki denying her entry into her own home was too much, if that's indeed what happened because I haven't watched. Uss ghar pe Pallavi ka koi haq nahi hai kya? Vijay throws her out of the house for a mistake, Jaya denies her entry for another. Do women have that little rights in their sasurals?
