Kesar's Trump Card??

When I watched the precap and Kesar said Gulaal will surely come back, he seemed too determined there. It made me think of his trump card. Is anyone else with me in thinking that he will tell her to come back or he will reveal that Dushyant killed Vasant and that she's known all these years and didn't tell the family? I know right now he isn't thinking straight and that is a terrible reason to get her home, but he has to get her home; he's so desparate. Isn't that his main goal right now? I honestly don't know where this show is going, but that seems like his next move. He has tried pouring his heart out and begging and even the sarpanch. I would think when faced with such stiff opposition, especially now from Gulaal's dad, he has to use his "trump card". What say????
