I can definitely do that. As far as what to do, it kinda depends on which Stefan you’d prefer to play (regular or Ripper).
If Ripper, we could have had Katherine actually step forward in the 1920s and he and Katherine spent the next century together.
If regular, a few options come to mind”
- Something while they’re both stuck in the tomb - Maybe Klaus didn’t send Katherine with the Cure so both Stefan and Katherine are dragged along with him during the summer while he’s tracking wolves and trying to create hybrids - Katherine’s scheme to break Stefan and Elena up actually worked and she’s trying to win Stefan over still
But I’m open to other thought/suggestions. I was just avoiding the whole human Katherine incident. ;)
