To be honest, I feel that Shehnaz's outburst after everyone chose her for being the jealous one over Mahira was NOT A DRAMA. I strongly feel she has a phobia of the word 'jealous' which is why she reacted like that.
It may seem weird that a person may have phobia of such a small thing, but it's actually true. Maybe there has been a big incident in Shehnaz's past related to jealousy word which is why she reacted so hyper.
I have been there in this similar kind of situation before so I understand what is going through Shehnaz.
Salman Khan was harsh to her, but he wasn't entirely wrong because fact is a lot of people don't really understand what is going through the person in that phobia situation.
More power to Shehnaz.
