the moon scene was just so beautiful... omkara and gauri stuck in their own difficulties.. if u notice both are stuck into forcibly marrying someone they dont want to..
the moon in the dark night is the only available light.. just like their lives at the moment seems completely in darkness and they are trying to gaze into the only available light...
gauri remembered all those times that she was in difficulty and how god got omkara in her life to get her out of it everytime.. she is still somewhere within herself hoping he will be the one to save her yet again..thats why she tried to touch the moonlight..
omkara on the other hand misses chulbul in his life.. even if he wont mention.. there is a lot of pain in him missing his friend now.. he knows chulbul would have come up with some solution.. but omkara made peace with himself that marrying anyone means the same..wether gauri or swetlana.. he can may as well save his family now.. omkara after getting ready for his wedding too thought of gauri.. and kali's words that om's chulbul is his bulbul now.. omkara does acknowledge his marriage but he feels that gauri is not a kind of person who can be with one guy.. so he just dusted off his thoughts..
so finally destiny will bring them back together.. the only way to save one other's life at the moment.. 😳
