I don't blame her family for carrying on with their lives while she was in a coma. I don't even blame them for getting Akku engaged to Aman. Difficult times can really test even the most solid of families, and Neha's family is no different. They are all human after all. And it isn't Neha alone that has to adjust to new things. It must be hard on the family as well. But I don't think they understand just how much it is eating up Neha from within.
She has woken up to a new world. And it was not by choice. Neha could not help her coma. And now she is left with no choice but to accept new changes in her life...changes that she never had a say in. Past couple of episodes have been very significant of Neha's state of mind. The first incident that comes to mind is the sari scene. Akku took what Neha had chosen for herself, which was quite symbolic. And her comment that she always wanted what Neha had might be a prelude to future events.
The second incident was when Neha and Akku were joking around with their brother. He teased Akku about her sasural and referred to Hitler Dadi - something that Neha associates with her. And then Aman was mentioned and her face dropped. She stopped joining in and watched her brother and sister having a good time. Once again we see Neha withdrawing, taking a step back and looking at how the dynamics of every relationship have changed.
Tum itna jo muskura rahe ho. Kya ghum hai jisko chupa rahe ho. So apt for Neha.
