Unfortunately for DD, she is repeating the same mistakes. Once again she wants to dictate Sid and Roshni's relationship and steer things in her preferred direction. It's sad because she has seen her daughter die a thousand deaths each day without Sid and yet she is hell bent on creating hassle.
But on one level I do feel sorry for DD. She didn't really get the chance to properly mourn the death of her husband. He came back into her life like a whirlwind and slipped away just as quick. And after his death she was busy with the mission of finding his killer. Now she is left all alone.
Her dialogue connecting the baby to Shiv a couple of epis ago was quite telling and very significant. It basically explains her possessive behaviour towards the unborn child and her bossy attitude right now. She feels as though Shiv is returning in the form of Roshni's baby and I can't help but feel sorry for her. Perhaps if Shiv was alive, she wouldn't be reacting in such a manner. But loneliness can do this to a person.
Having said that, I still think DD is in the wrong and she is walking down a dangerous path here. If she carries on like this then she will end up pushing her daughter away once again. Roshni should be enjoying her pregnancy and should be able to share it with her husband. DD is a mother and it's a mother's job to worry. Except this is beyond worry. It is madness. And DD's OTT reactions are only causing Roshni discomfort and in fact doing more harm than good.
