JW punished Bani after their wedding for pia's sin. Now how should he punish pia for even bigger sin that she is commiting. not ONS. She is commiting the biggest sin by breaking her sister's marriage.
since she is pregnant😕 and JW knows her intentions. he should treat pia worst then ever, once bani leaves WM. PIA ko jahannam ( HELL) kya hota hai pata to chale. JW knows, jahannam ka rasta logo ko kaise batana hai. I hope he doesn't go there by accepting PIa
