Hades in “Unfinished Business”

Hades

[After summoning Fendrake and revealing him to Gold] Remember him? You two had a contract. You tried to void it by killing him during a certain potentially baby-making liaison with your protege, the Evil Queen's mother Cora. You rascal! [Chuckles] Which seemed smart at the time, but it turns out death doesn't actually nullify a contract. Not down here. Because here he is. And here's the contract– [Produces the contract] which he just signed over to me. So, just to be super extra clear, at any time, I can cash in the debt and take your baby. All magic comes with a price. And now, Dark One, the price is you work for me.
