It was before the lake that Dutta cleansed himself of all his memories, of all that he keeps locked inside, all the things that trouble his soul...those things that keep him from sleeping, keep him from being happy, from being INSAAN.
So it is that we find ourselves with Naku by the water, revealing herself. Intentionally or not I do not know. I myself hope it is all intentional. This is her turn to cleanse herself of her secrets, of the very thing that locked her up, kept her from living...from being happy.
I do hope that the reveal does come to pass tomorrow or Monday. This is how they part ways, both knowing each other's secrets, unburdening themselves of their guilt. And leave the decision in each other's hands.
