He needs to have a pair of balls to take his own stand. Bada aaya tha pizza aur sex wala. Kahi ka nahi raha. He just wanted to target Gautam and become the MALE HERO in the eyes of the witches and started saying shit to Sonali and making an issue out of nothing. I mean, seriously. Singing a song to a girl? Did that hurt his soul because all the girls consider him a "brother".
In fact, if you look at the whole issue, it was literally made out of nothing. First Karishma starts it, Dayandra drags it, Deepshikha conspires, Arya is thinking how he can become the hero, Sukirti starts another issue out of nothing & brings her team along to corner Gautam again, and they jump on him. They just need a reason to fuss with him. There isn't any ACTUAL issue.
