The Craft: Legacy immediately ends after viewers see Nancy.
Now because Nancy very much still seems to be locked away, and the combined details of Nancy experiencing trauma, we can assume that Lily’s father isn’t a good guy.
Lily learns towards the end of the movie that Helen (Michelle Monaghan) isn’t her birth mother and that she was adopted, a secret Helen kept from Lily all her life.
We saw so little of Nancy that we can’t really figure out the mental and emotional state and whether she’s a good or bad witch now, or still no witch at all.
