The mystery phone call

The episode ends in great suspense today, any guesses on who called Thulasi and what it could be about? 

I think it is Prabha. TA mst ave come to office to look for Prabha.

I'm thinking it's Prabha also. 

So it's not Prabha or Mohan based on yesterday's episode...

Lol, we were all wrong, it was Padma!
