Nice points. Gulaal doesn't want anything for herself in her life...she has dedicated everything to Vasant's family. But Vasant and Kesar are the only ones who are so close to her that they affect her deeply which explains why she has become so happy seeing Kesar behaving well with her.
Given her dedication to see everyone happy, and her plan since years to get Kesar and talli together I doubt whether she'll be less than happy to see Kesar taking care of Talli and not herself after marriage. So as of now I am not getting any clue about any feelings from her side. But there might be a possibility somewhere... The thing I want to see now is how does she realize that she might want to have Kesar by her side always.
Another complication is Kesar's angst regarding Vasant's death and his Talli connection. But I am sure that Kesar's situation can be resolved easily when gulaal is in the picture and I think he would be quite clear at the crucial decision making hour in terms of what he wants. Its Gulaal who is not opening her cards yet.
