Play on guys insecurities
Create a dejavu situation
Make a understanding and mature wife act in immature way and unnatural way beyond her real character
Make a wife who used to understand husband feelings when they were enemies now totally oblivious and naive
Make. Wife behave with a friend in such a way that it seems her life was worthless Nd non functioning before friend popped up
And then pull a trump card
Make a guy who was giving moral science lectures few months back behave like a animal with his wife
And you have a result
Husband who was proved wrong and bad
Wife mahan and hurt due to husband doubting her character
And new entry friend justified
Even If show is damaged
