I think that when Jai finds out about Bani's stupidity he should say enough is enough and just leave Walia MAnsion and allow arrogant Bani to continue on her path to self-destruction.
If he stays and is forced to go along with the nonsense God alone knows what will be his fate.
He will ultimately be blamed for everything negative that happens.
So if he does leave and perhaps stay in the penthouse suite in his posh hotel, he will long for Bani, perhaps grieve but he will also have some degree of peace of mind and eventualy Bani will be forced to regain his love and trust on his own terms.
He needs to get over his weakness where Bani is concerned.
