Gautam shouldn't have said ki "woh le gayi thi mujhe washroom mai" BUT its not like he doesn't understand and ADMIT that he is responsible too. When Punz and Dimpy told him he is party to it - HE AGREED. Now would you give him credit as he did agree that its his fault too and that he will have to address it with Diandra? Or would you just like to call out a fault again since he didn't agree the first time?
He's admitted once that he's wrong too but put the blame on Diandra 10+ times. If he keeps repeating it obviously he's going to look like a wuss that can't stand by his actions.
