Once, during Diwali, on Prashant's instigation, Yash had asked Aarti if she felt bad about him still keeping Arpita's photo in his closet. He had asked her if it was necessary to erase memories of old relationships to make place for new relationships. And the answer was no. Looking back at Aarti and Yash's relationship, we can see how Aarti has made a place for herself without ever demanding that Yash erase Arpita's memories.
Today we see the characters in a similar situation. Once Akash is accepted wholeheartedly into the family and Yash's position isn't threatened any more, will Gayatri and the rest of the Scindiya's expect Yash and Akash to erase memories of Radha? I doubt if Radha will continue to stay at SM but will Gayatri be able to share both her sons with Radha? Can the two mothers, Gayatri and Radha, coexist in their sons lives.
