I don't understnd what is Sameer's f****in' business to take on Dolly for Shweta Tiwari. Dolly is rite when she sayz Sameer bhai ki buri aadat kay woh chalti train mein chadte hain. If Shweta's got a problem with Dolly she can sort it out herself, she is cunning in involving Sameer as a shield, he then gets hurt from both sides, one from Dolly another by reacting and showing what a big L he is whereas Shweta ji goes behind him, and kinda wins in her own way, hiding the real Shweta Tiwari behind the fake one.
I've a feeling like Khali ji Sameer bhai has the hots for Shweta Tiwari, one can see that during gal mitti bol dance how Sameer ji was blushing and visibly refusing eye contact with Shweta ji as he was clearly awe-struck by her dance act.
Sameer should'nt get into issues which pre-date him knowing Shweta Tiwari, and the problems Dolly have with real Shweta Tiwari. Shweta won't give a rat's a** about Sameer once this show is over, and he mite not like the real Shweta Tiwari.
