I totally love the use of Ayaana and Roshni., by Aman.
Ayaana comes when she is fulfilling her responsibility as a saviour. Like she jumped in the well to save Chotu, that's Ayaana for him. And Roshni is a personal thing, like he screams her name when she's gone and also to revive her, he keeps calling her Roshni.
Smartly and effectively used.
