Four of the guys together covered Sambhu trying to take her away from there. I am sure if they wanted to Upen, Rahul could've managed to make Ali shut up when he was provoking GG, but they did not. Why? Simply, because it was Gautam.
The only point I am trying to make is, that the HMs should stop claiming they took a stand for Gautam because if they really wanted Ali to shut up they would've grouped up to shut him like they grouped up to make sure Sambhy/Dimpy fightiisn't too escalated.
Just saying!
