What hero?
He only did that coz he knew Sid was this close to popping a vein and hitting someone physically. He simply intervened so that he doesn't get thrown out of the show. He didn't call out Shukla on his BS. Rather kept saying Tu Bahar ho jata agar tu maar deta. That doesn't make him a hero. He is complicit too.
Rashmi's done this many times. Be it in Devo-Shefali fight or the one between Shukla-Paras today. And She barely had an motive as such.
