I think all three of us are in agreement that a romance between Nick and Adalind is disgusting. Whether the creators will do it or not, I don’t know.
If Adalind keeps in character, now that (if) Juliette is dead she’s got no further use for Nick, and will use her mother’s or Henrietta’s body to regain her Hexenbiest powers and go back to causing havoc. Being with Nick wouldn’t bring her the power and money and the sort of life that she wants.
Here’s hoping, anyway.
