What I'm about to say isn't some well-established theory, just a thought that crossed my mind.

I think Catelyn will reunite with her children again — at least some of them. And I honestly believe it will be one of the most heartbreaking moments in the story.

Lady Stoneheart, this vengeful and broken shell of a mother, will finally crumble the moment she sees that the children she mourned for so long are still alive.
