Go back listen to the episode properly. when suyash was being verbal with mandana Rochelle told him to calm down and said I m here to mandana when mandana told here to be quiet. Rochelle then said how can I be quiet being a woman. If he crosses the line I will stop him. Right now he hasn't crossed the line he is ok. But she stood up for mandana. So go listen with your ears properly
Oh I've watched very clearly. She was stating Suyyash is within his limits despite of giving open threats. If she couldn't call a spade a spade then in what sense was she even 'trying' to help Mandy? What Suyyash did since past two days was gazillion times worse than what Suyyash and Prince together did in rickshaw task: remember the comments Rochelle made on them back then? Forget that, just the day before she told Nora Mandy didn't push Kishwer, and later on have Kishwer benefit of the doubt. The contradiction is just too much and Mandy was right to stop her right there.
