Gayu, I think you might be right about the bail. He will make a condition that she cannot to go Trilok's house so all will have to move into AN. Let's see what happens.
Kalyani herself is wary of this Trilok and doesn't 100% trust him but for Pillu, she is willing to do anything. And she is convinced by Suhana mostly.
Also, I donr think its Kaka replacing Mai's medicines. Overall theme is that someone is tampering with all the medicines in AN and Trilok is the owner of some pharmaceutical company supplying the medicines so no coincidence.
