Jai must have loved Pia and that is the reason for his anger but now from the last few episodes I have noticed that when the background song "Adat si ho gayi hai" they are not showing Pia's pictures where as before they showed her pictures evertime......
Like on the beach in goa he is thinking but about who - Pia...Roshini...or Bani.
Maybe he is falling in love with Bani and he is afrais as he knows she was against his marriage to Pia and he once again do not want his heart to be broken into pieces. ........Thats proves his anger towards bani which sometimes is out of place and time....
Yup I surely think Jai is in love with Bani.....and he is in denial.
