this is just my perdiction but i believe that ipshita is in on the plan with nikhila because its too much of a coincidence that she came back from london the same time that samar was entering their lives and also she kept shiv away on buisness so i think this whole thing was intentional and ipshita is plotting to get him back
also tomm i think that ipshita is going to pretend that her and shiv slept together and shiv wont remember a thing because he was so drunk and then she will probably use the whole guilt thing and when gauri finds out shes gonna think that shiv wants to be with ippi and she will leave
