Don't understand how Gautam's act is similar to Upen's?
I mean if Gautam was given the power to nominate and he nominated Dimpy then I would call that backstabbing. But he did not do that, as he was not given the right to nominate, and if he was given that power, the he would not nominate her. He did not save Dimpy and did not nominate her, so what's the fuss?
Whereas Upen's act was so obvious and tactical, as he nominated P3G and Sonali. If Upen did not nominate Pritam and Puneet, then I would say Gautam and Upen's act were similar.
