When Sameer, who spends 24 hour a day with Shweta, and is sharp and intellignet than probably all of us, does not find anything wrong in her and goes to such extends to support her, why people talk agianst Shweta and conspiracy theories like she was waiting for this opportunity.
She is luckily captain coz of Veena, Dolly already made up her mind before entering that she would make it difficult for Shweta.
Shweta even looked set to forgive Dolly and carry on with the PT session, and solve it in the confession room but matter was dragged. Even she never might have thought that Sameer will go such extends I feel. So she was sort of shocked and didn't react at first, but good that she supported Sameer despite being manipulated by Manoj and Seema at the end.
