I'm actually repulsed by some of the posts I've read here, implying that Yash will be dirty if he is someone else's son. Uhh I don't think so. I disagree. There's nothing, and I repeat nothing wrong with the child if you were born out of wedlock. It isn't the child's fault!
I'm looking forward to this track and I sincerely hope that Yash turns out to be Radha and SP's child just so the CVs can send out another powerful social message about this.
