i feel biologically knowing about the mother had affected her quiet truly . And the relation between indu and shweta must have been affected . I agree regarding indira memories should not be erased , but i feel that was done for indu . Everything here was done for indu , for her upbringing . I don't feel if rishi was a little more friendly towards shweta , than she would have taken in wrong way . She has always understood his love for indira . His avoiding her makes her do things to get his attention .
Its not possible to have a platonic relationship when one person in the relationship clearly wants more. If Rishi were firendly, Shweta would probably infer all the wrong things. Another hindrance to them having a friendly relationship is Shweta's constant efforts to "erase" or "hide" Indira's memories. If Indira's memories were acknowledged and celebrated by all in the family, the relationship between Rishi and Shweta would have been much better as Rishi would not be so insecure about losing out on Indira's memories. It is such an insult to Indira that her daughter does not even know about her biological mother and I blame both Rishi and Shweta for this.
