As much as we would all like Khanak to remove Suraj's picture, and show that she is willing to move to, am not sure that will happen quickly. I would be very surprised if it did. Khanak removing Suraj's picture is a huge step, and the CVs won't show it so soon.
It is not the same as Shaan removing Natasha's picture. Natasha is not his wife, she is his girlfriend/fiance who he still hopes to marry after 5 months. She also understands his situation. His whole family knows how he feels about her, including Khanak. But no one from Khanak's family knows of her existence since he removed the picture before they could see.
Suraj is not a boyfriend waiting round the corner for Khanak. He is her husband and now dead. It is a different matter removing a dead person's picture, especially by his widow. Plus, Khanak's family would think she has forgotten him if she removes the picture. Khanak would not want that. Everyone knows about Suraj,including Shaan's family.
Khanak removing Suraj's photo will happen, I think, when she really is ready to move on with Shaan, and not because she wants to teach a lesson to Hetal. With Hetal around, removing the photo will only invite more trouble for Khanak.
Just a guess...
So for me, her next big step will be to become more close to Shaan in other ways. We may get scenes we get in umpteen TV serials- Shaan coming out of the shower and accidentally bumping into Khanak, tying the dori for Khanak' blouse, tying a chain or putting on a bangle, u know... the usual stuff, which will signify to us that the two are getting closer.
I would like to see Shaan move from sofa to the bed. That should be Khanak's first step. Poor chap will get his back injured sleeping on a sofa. It looks very uncomfy!
