I'm actually so curious to see where this story line leads too.
Rape is such a huge issue, all around the world. And for Ekta to make a mockery of it, it a pretty bad move. I don't think she'd be that dumb to just ignore it. I hope it gets resolved in a proper way (i.e Pihu being found out, her apologizing to everyone, and sent off to therapy).
And regarding Priya and her blindness, well honestly, I think its a pretty predictably move. Priya has been shown to be "smart" one. She thinks she figures out things quickly, that her hunches are always correct. When she starts thinking like that, nothing can change her mind. She's very stubborn. I remember when Ayesha started to go bad, at first, Priya had a hard time believing it. Only later did she realize her mistake. The same thing is going on with Pihu. She won't stop believing her daughter's words, because as she pointed out, it would be the fault of her OWN upbringing. In some ways, its a matter of her ego. I'm pretty sure if Priya looked a little further, she would find out the inconsistencies in Pihu's story. But her pride won't let her.
Actually, I think Priya and Ram's reaction is pretty realistic. Priya refuses to believe that her upbringing failed, and I think a lot of parent's face those same questions when their child does something wrong. And Ram is going to use his power to destroy the guy who allegedly hurt Pihu. A lot of rich people prey on the poor. There's been quite a few instances of peoples lives being destroyed because they don't have the resources to fight back. And even as a father, Ram's reaction was believable.
Anyways, I just hope Pihu doesn't go unpunished. That would be ridiculous.
