Because SP showed no remorse nor guilt for humiliating his own flesh and blood in spite of the fact that he knows the truth. I want to see him ruined and shattered. I remember the way SP mistreated Aarti and her in-laws for hiding the real status of Aarti, as if SP has no dark secrets. This man pretends to be righteous.
Loved your written episode adding your thoughts on right and wrong. Absolutely agree with you. What remains to be seen is whether Arti will say the whole truth - if so, whether Yash will react the same way as half truth or will he fight for his mother Radha. According to me - Yash may protect his family and try to be loyal staying away from truth for a while - but circumstances/situation/ Aarti on the other side of fence may make him realise whether what he is fighting for is worth it - especially if more insults are thrown at Radha and Aakash in the future episodes to come. Lets see and wait . One thing is sure - brilliant performance is what we all are going to watch from one and all.
