her love for sid was not true that was puppy love...teenage obsession...remember how he used to say ohh hes soo coool and ask him for diamonds and stuff? well yeh that is infatuation! she loves her parents very much but in her stupidity to harm ichha she cant see that she is hurting them. As for nani she didnt give nani any dhoka cos nani has only supported her in all this!😡
