Twelve pomegranate seeds.

Hades tricked you into eating twelve, so now you're stuck with him for all of eternity.

He sighs. "Darling, there's no point in fighting. You're mine, whether you like it or not."

His smirk only grows when you hiss that you hate him.

"Hate is a strong word, love. A very, very strong word. Hate me all you want. You're stuck here."
