Preet and Naina's plan was like Shergill's.. Very silly... Naina stands for Baba and is gang... Trisha stands for Preet...Bilal stands for Rizwaan..
Preet's dialogues to Naina were as if someone was questioning the motives and actions of Baba and gang...
Shergill will accuse Rizwaan.. But Preet will blindly trust only Rizu just like Trisha did on Bilal... Sheru will tell Rizu I will expose you...like how Preet told Naina...And like Preet ka popat hua Sheru ka bhi popat hoga...
But now slowly Rizu will start getting strong guilt feelings...like Bilal... Bilal's dialogues are a reflection of what Rizus state of mind will be... Preet's dialogues to Bilal were questions to Rizu actually...
Ishaan supported his family only...blindly...Like how Rizu supports Baba
And his gang...
