Too many coincidences have been woven in story to give the final outcome credibility...Why did not Deepak even once try to meet Gautam after he was out of coma as he was the only loose end who might have seen Rajeevs face..if he did why was it not mentioned..Nobody mentioned to Deepak that Gautam was out of coma?...Why didn't Rajeev have his fathers residence key? Why didn't Rajeev call the police stn frst to asertain his fathers presence there.the name Mano n the correlation seems out of place just to create a plot decive...writer has intentionally or unintentionally left these loopholes for the final shock value which is worthless.
