Rewatched episodes the previous PD track onwards. Having watched those, Aditya on the bridge just became the obvious culmination. On that bridge, he was a man who was not ready to let go and one who could not help himself but hold on to the last remaining indentation that Imlie had left with him. My perception from the day I viewed the episode remained justified.
The last time he was in PD, it was a turning point unlike any other because he decided that Imlie was safe only if he was around. While he could subconsciously not fathom living without her, consciously he had decided that her care was his prerogative. Cue the hospital visits, worry about the stitches, concern about overworking etc etc. all this was happening in parallel with him opening up to her a bit more each day in a way that was not possible with Malini. Rupali hints at his coming home on time every day while pulling his leg the day he misses Imlie and that should have been indicator enough that him missing her is warranted. But now that I rewatched it, it became glaringly obvious. He was already used to having her around but that day, he became flustered as well because he no more had control over her well being with her being at ACs place. And he did the only thing he could thrash around at the people who he decided were the cause of her agony.
By the time Aditya came to PD this time around, he was so knee deep in his connection to Imlie that when her staying back seemed inevitable, Aditya did the only thing he could with that spot of sindoor. Hold on to it. The continuity in that spot on his shirt could have been handled better though.
And lastly the Aditya we saw in the pooja episode is the one who has started listening to his conscience. “Agar yeh sach ka ehsaas hone ke baad bhi tumne usko nahin sweekara aur iss sach ko Malini ke saamne nahin rakha toh yeh sabse bada dhoka hoga”.
He is going to return alone. Imlie will miss him. He will miss her. I do not think he is going to try and bring Malini back on his own but will do so only because the Ts have been destroyed by her leaving. This is an Aditya who is only going to get more selfish in his quest for love.
