Each of Raman's 3 children have endured different life inputs. Ruhi had love and effection of all and became the Dadiamma bringing her best friend Ishithaaunty into her home as her Ishima. When her ties with her are severed like Adi i the phase 1...she has hatred on the surface and prays to Matarani to keep her safe...she wants to spare them from the trouble Nidhi can unleash. I hope its the last weve seen of Nidhi.
Adi's life altered and Ishita picking his mom Shagun from the dustbin and the way things lead up to the earthquake and thereafter gives him reason to live by her values. Shagun too refers to Adi as Ishitha ka beta. Her influence in shaping Adi has been undermined as much as Ishitha's has been exulted. To Adi Ishima is the reason his papa changed. The intensity of her influence on the adolescent Adi is very deep as we see in Aaliya too.
Pihu has the DNA of Ishitha the Jagga jasoos connects the harwali Aunty but does not spill it all. Adi tries to build the bridges in the hope that that is what his Ishima would have wanted him to be.
Aaliya too has experienced the unconditional love of her Amma.
All the kids whom Ishitha has treated she calls hers in the first few episodes. All the kids that have spent time with her think she is their mom.
We say in Tamizh when you nurture others kids as your own yours grows and thrives on its own that seems to be the case with Pihu.
Its Adi and Pihu's turn to play cupid...Alias is an aborted futile mission.
