Death Do Us Part

HONEY, DOES THIS TASTE LIKE POISON TO YOU? While sitting on death row, I'm given two choices: 1. Be horribly tortured in a way that ends with my intestines being pulled out of my anus. Or 2. Marry the tyrant fairy king. He might eat babies and bathe in their blood, but he's dark-haired, with violet eyes, and oh gods, he's pierced. Deciding I can fix him and his entire backwards kingdom, I willingly say, "I do." But the thing about fairies is, they're sticklers when it comes to wording. So when I realise I only got out of being tortured and not out of the entire execution, what choice do I have other than to kill him first? But how do you kill someone who's bigger than you? More dangerous than you? More knowledgable in the art of death? The only time his guard seems down is when he's *eating*, but it's not like I can just poison *that*... Can I?
