I read many people call her immature. I do not think that was immature. She was angry and she let out her feelings - unlike most people on the show who just shutup as soon as they're one the stage. I applaud her for her boldness and her maintaining WHO SHE IS rather than turning fake.
It's a bittersweet dose of reality. I found it rather funny that the show instigated Gurpreets anger and wounds and then when they got the reaction - they asked her to apologize too. LOL. That's what you call TRP.
I still didn't understand why Yashs mom does not like Gurpreet. I'm from U.S so the episode with this argument did not even air yet - I just watched it online - but it's confusing.
