He told Priya truthfully that he has nothing to do with Juhi. And surely she believes him whole-heartedly. I do agree though Ram isn't going to be handed a scot-free ride. But he cant be penalised for everything. Yes, he should be spending more time with Priya and helping her around in catching up with the 7yrs gone by. He needs to look into what Priya feels for right now.
I must say apart from Ram having the opportunity to confess the marriage story a number of times, they have NOT shown Priya sharing her difficulty to come to terms with the present situation. She isn't opening up to her MOST trusted person, then how do you expect him to read her mind?
All's fair in love and war. Let's face it, the war is no or less an episode or two away. As for love, surely it will come around once the war dies down.
