Cora not having a heart reminds me of the Russian fairtale “The Frog Tsarevena” featuring an evil wizard named “Kostshei the Deathless”. Kostshei cannot be killed because he hid his life force in the tip of needle within an egg which was inside a duck which was inside a hare which again was inside a chest which was inside a large oak tree. (Talking of safety meassures running rampant)
Hey, that’s similar to the Giant Who Had no Heart that I mentioned! I had no idea there were more fairy tales where people hid their hearts in ridiculous places like that >w< I'll laugh my head off if she has it in a place like that, and seriously approve of it too.
