tanu clues..

Twice after purab showed his recording..tanu kept saying that she had the original video...and then she realised what she said...purab however should have told her that she may be good at lying and keeping secrets..that is why she is quick to say the same about pragya...that would of planted some sort of question in abhi's mind...i was hoping that when he was telling her about how she would have to shut up..he could of brought in these lines..would of really shut her up..
