If Bani is going to go away from WALIA MANSION as the previews are pointing then I think today Rano paved th eway for Bani's exit.
Rano went to talk with Jai but end up giving information to Ranveer. And as we all know the sole aim of Ranveer is to bring his mom back in the house and he will use this to throw Rano and BAni out of hte house.
If left to Bani I do not think she would ever leave Jai own her ownđ She is too too much in love withhim and now I think that Park road incident would make her angry but not make her leave the house.
