That willl be really digusting.
He knows that JW loves Bani contrary to what she is made to believe. He knows that Bani's hatred of Jai is based on a lie. Otherwise he is her life.
No matter how much he hates Jai or how he thinks his revenge is justified he should come clean with Bani about the truth about Jai if he claims to love Bani.
If at all he proposes her then he is just llike Pia. Selfish obseesed.
Or is this why he won't be negative character & will actually get JB together just because he starts loving her. That will be interesting turn.
