Maybe Raghav and Paakhi are playing a joke...
I know its a kind of sick joke, and looking at Raghav's face doesn't look like one but who knows , maybe it is . Like the results ka time, he disappeared and everyone thought he ditched kalpi? He decided to clear the results first so Kalpi can then confidently talk about her marriage plans to her mother.
So he knows that Kamla is worried about Paakhi's reaction to his marriage to Kalpi and he told her don't take any tension, he'll handle Paakhi. So maybe he went and talked to Paakhi about his feelings and made her understand that he never loved her in the first place. Paakhi then agreed and they both played a prank today. Then tomo Paakhi will say to Kamla, how can u think I would come between two people who really love each other. You have brought me up to be a sensible person etc etc...I know this is a far fetched explaination...but its the only one ot redeem the show...
Rags being blackmailed : kuch hazam nahi hua...
First off, what will they blackmail him with? His mother? As soon as he sees his mother , he will know what has happened and will put 2+2 together that's why they made such an effort to hide her...Also won't he question the kapoors why they didn't tell him before about her? Why now? Also kamla will ask about tai and spill the beans that tai is the same woman who was being chased by goons. Raghav will then know it was Kapoors all along. Also Raghav doesn't love Paakhi and will use her for revenge as soon as his mother is given to him. I eman, if he's being blackmailed , as soon as he marries Paakhi , he will get his mother, then why would he care for Paakhi? he will drop her like a hot potato.
No, I think this just might be a sick joke..and I hope Kalpi gives him a good tight slap for this...
