I pretty sure talks about remarriage will be touched...it might happen after 5 yrs of leap and probably by Singhs because obviously Shekhars would't want to do anything to lose Shiv's kids.
For now i don't want Anandi to remarry because no one can love her and her kids the way Shiv did...i know i'm being selfish and maybe after few months when i'm over Shiv's death and feel Anandi doesn't deserve a fate of loneliness then plans for remarriage might be ok but even then it should be completely Anandi's decision although it's very hard to imagine a guy better or equal to Shiv who will accept AnSh's kids without wanting his own...Anandi's third marriage will look like a joke because Anandi loved Shiv so much and though no one deserves to be alone it's still an insult to AnSh's love.
I still don't get this decision to bump off Shiv at such amazing moment of his life...BV could have ended well within few months with all the problems solved in both KB and BH and both AnSh and JaGan living their lives with their kids...why are they doing this?
