Did mandana play a masterstroke today?

which means she knew based on the assumption that Giselle would have conversed with Mandana about prince being the killer and she also knew rishabh wasnt the killer coz she and rishabh must have spoken about it and also that rishabh was a detective

next I am sure hundred percent that she wouldn't have helped Priya in any case.

So I am thinking she said that to priya to play reverse pyshcology coz she knew priya wouldn't believe anything she said and also that the cool group wouldn't believe her anyways. Also her statement of Rishabh being the killer was to distract priya away from suspecting anyone else and also trying to deviate from the actual killer whom Rishabh had already zeroed into...

I also feel she asked Rishabh for help coz she knew prince was not being himself in the kitchen and it was a ploy and rishabh can collect evidence .

I can understand suyash helping priya coz he didnt want rishabh to win but why would mandana help priya that too against rishabh whom she is close to?

I am not sure if it was reverse psychology or not but ManD instilled doubts in Priya's head against Prince. This way Priya would be cautious of Prince and wouldn't let him murder too easily. She also knew that Priya will still suspect Rishab as he was with ManD when she was murdered.

I dont think it was reverse psychology as such, but she made sure Prince wasn't successful in killing all and indirectly helped Rishab win.

Coz ManD told Priya 'you and Rishab should work together to catch Prince'. So even then she had Rishab in mind. She wasn't helping Priya. She was helping Rishab

Then, when next murder happened Mandana and Kish were sitting together in coffin area, they were not surprised about next murder, but when Nora was announced as murdered their reactions different, especially Mandana screamed 'What' with such a surprise. After, its doubt between Rish and Prince.

Regd, Mandana informing Prince as murder to Priya, i thought she genuinely helped detective to catch the murderer, but Priya didn't believe in Mandana's words.
