in the current scenario, I understand why Priya doesn’t want MM to know before clarifying with Ram, my comment is about Priya not wanting her mother to know about MS attempting to murder Ram.
Ohh ...i thought you were talking about ram and vedika.
I think not telling Meera is about that Priya thinks that Meera still has feelings for MS and will be hurt that MS is a murderer.
I can't think of any other reason.
