Said this before in another thread:
I don't believe at all that he technically cried just for Sree. It stems from how much Surbhi words of abuse and questionable remarks on his character were still hurting him, seeing Sree in pain and possibly missing his own kid.
We can see Romil has been down for quite some time, and through frustration he shed tears as he couldn't control them anymore. It got even worse when Surbhi got so favoured that whatever she said and did to Romil was never touched upon by Salman in this episode in such unfair fashion, so Romil reached his breaking point. Even when he was in the opposition side, we saw him feeling bad for a depressed Sree compared to his useless ex friends.
He has every right to feel upset and cry whenever he chooses to be. He's a human, not robotic. No one can judge him if he wants to cry a lot. Judgmental people calling him fake are the worst. Crying makes a person feel better after having such dark more than vial emotions repressed for quite some time.
