I want to see the show visiting Arpita's deceased husband's birthday. Maybe with the date approaching, Aryan has nightmares and Imlie consoles him, seeing him for the broken soul he is. Kind of like the scene from Qabool hai where Sanam comforts Aahil. Then, they have a sequence like the song gun gun guna re with Imlie trying to get the family to celebrate Arvind's life rather than mourn the death. And the Tripathis look on as the Rathores, including Imlie, look like a picture-perfect small family.

Then Aditya confronts Imlie afterwards, trying to justify himself so she doesn't see him through Aryan's vengeance-laced eyes.
"Imlie, woh ek galti thi jo saloon pehli hui thi"
"Jaanti hoon. Par uss galti ki saza kitne log jhel rahe hai, woh shayad aap nahi jaante Aditya Sir." and with that she storms off.
