It will be Guddi who may expose Suman. She must be boiling inside for being burnt alive and losing original face. Further she loved Ravish, not Atharva. She knows Suman is dangerous and so she maybe bidding her time to take revenge.
The marriage shooting was not at the behest of Vividha.
So Atharv is being drugged and Ravish is being kept in the dark.
Madhav's sixth sense is making him not to trust Suman.
Suman is playing double role. One for Raghav and another for Ravish.
She has become the central player, better than KK.
