You know i wondered the same thing. My thinking is that she wants to gain Mandhar’s trust so he confides but he has already told her so why woukd he confide again. She never recorded it. She is queen of recording it seems. Lol
Also what are their plans in find out what happened? They already know what happened so what do they want now. Mandhar to confess maybe?
As for pallavi running out, she was afraid he would kill aai….oh wait i forgot they were alone🤣 but then he wouldnt trust her so she stayed but she could have asked amruta to do her a favor and stayed in the locked room when Amruta came to unlock her. She could have said send a msg to farhad not raghav because she knows raghav would get upset and shoot anyone in sight but if farhad knew then he would be able to relay it calmly to raghav after he got the divorce papers. Maybe even a msg like please ask raghav to read the divorce papers carefully. Each line. Etc.
