It is Ram's insecurity...that is making him react this way. The man in falling for his wife and he fears that she might not reciprocate. I'm sure they will show shreya or Kriti filling something in his mind as obviously there is going to be no patient there in the clinic
This is exactly the reason behind his outburst or questioning Priya. She might have been late for the death anniversary ritual. And since he is looking forward to be with her and everything, her absence or delayed arrival might have created a huge disappointment and a rage of insecurity. Fueled by Kriti or Shreya possibly.
So he is just showing it on Priya.
This scene is reminding me the one with R's birthday and how he gets upset and insecure over the fact that she didn't consider his birthday important or went with Krish or something.
And only when he gets to know that she went all the way for that favorite cake of his, he comes around and apologized.
Now the same is happening here.
