umm i think it's just going to be a dream. Just thinking that it's a serial, they kinda have to stretch the track out and so Adi getting to know the truth would be too soon. If Adi gets to know of his father's truth, I bet he would go directly to his dad and demand the truth. It just seems too early right now.
I personally do not want the truth to be out so soon, I would rather want to have some nice episodes of Priya and Adi developing their relationship deeply. Once that's set and once Priya has some solid proof, she can go ahead and tell Adi.
p.s. my main concern right now is vidya-gaurav, they need to move that track faster!
