HS' reaction when he realized that the wedding video had equal footage of him, as well as special moments that Minnie had included which beautifully captured their bond and their happiness at being a family... Damn fine actor Aniruddh is.
Linked back to what he had said about Minnie not being able to hurt her mother but could hurt him... Well, the evidence was there, he was just as important a part of her life and he had always known, and this was a strong reminder that it had all been in his head, her love and admiration for him had not changed one bit.
