It's another to figure who laid it, and why.
It is yet a third to figure out how the main character will learn all about this.
Especially if she's not even the butt of the curse, and has no notion why it was laid in the first place. And is kinda of busy trying to figure out a completely different problem.
That's the fun of trying to have revelations in the tale. And magic is particularly hard to reveal, since it revolves about action at a distance. sigh
