If I were a writer, I wouldn't have written the hostel scene at the end. Anokhi should have said, no, he is not here and why would he be or something like that.
The way it should have worked out is, Shaurya would call them saying ACP just found him unconscious and explained how the family was looking for him and ACP could have told them where they are and promise to get him home. That is easier to buy rather than this scene, nobody would believe in this.
Devi's questions were spot on, I would ask the same question. Creative writing without proper logic, analysis kind of goes ...
