A well crafted episode, remniscent of the early DMG days....full marks to the creative team...
While Ridhima's unspoken surrender and Armaan's aching yearning for her was very natural (which I suspect is a dream), to me the defining moments of the episode were different...
Ridhima's capitulation to her emotions and acknowldgement to herself, as she hands the baby to Armaan, and, sees in him, as a culmination of all that's happened in the last few days, a kind, caring, considerate, loving man, an infalliable friend who can be wild, passionate yet incredibly gentle...
Armaan's disbelief, and, his yearning when Ridhima involuntarily bares her emotions for him to see, while watching Chirag & Ritu...his melancholy, a wistfulness and a fledgling hope that his desire is being reciprocated, longing to hold her and reassure himself yet unable to reach out lest he destroys the phantasm...
