How did munshi know rajveer is part of the plan

But I'm wondering how the munshi came to know that it was geetu AND rajveers plan. He told kavya that geetu is chamki and geetu and rajveer both planned this to take revenge from them. Now we know munshi came to know that chamki is geetu when rishabh confirmed. But how did he come to know that rajveer is also a part of the plan??

Is it a blooper or some clue towards who is saheb. 😕

On a serious note it is not difficult to find out for a thurd person as Rajveer and Geetu's full attention is on Abhi they have never noticed if anyone else was on their trail

Also i feel geetu and rajveee were quite dumb in the hospital anyone could have heard them and actually Kavya did

The way these two keep discussing plans without taking any precautions, even Sevakram must be aware of their plans by now.

I think Munshi is working for a person who knows everything about everyone. May be that person knew everything about Geetu-Rajveer's plan. So may be Munshi also knew from the very beginning that Chamki is Geetu, before Rishabh told him this. Not only Munshi, Priyam is also working for that person. That person may be Rajveer himself, or someone else. May be it's Ragini who is alive & planning all this!!!! Whoever he/she is, he/she is very clever, he/she knows everything about both Abhimanyu's & Geetu's plans, & wants take advantage of all this for his/her own purpose.

And then like @Urmita has mentioned above it's not that Rajveer and Geetu ever discussed their plan in a hush-hush tone.
