"When I was ten - actually ten, not just looking like it - my sister went through a portal into another world. It was called Narnia. She met a faun, and she had a lovely time, and she came back to us and we didn't believe her because that's not how magic works. I went through the same portal the next day, and I met - a woman. She was beautiful, and... she bewitched me. Not any kind of magic I'd heard of before, just - I wanted to make her happy, and I'd do anything to make it happen. I promised to bring my siblings to her castle, even though I think I knew that she meant us no good. And - I tried. But they were too clever for me, so I ran back to her. She was... angry. She hurt me. She was going to kill me, but Aslan's army rode in and rescued me."
His eyes are shining. "And... they brought me back to my siblings, and I told them I was sorry, and they told me that everything was alright, even though it wasn't. And then the Witch came and told Aslan that I was a traitor, and that by the Old Laws she had every right to me. And he told her she was right. But then he said that if she relinquished her claim then he would give himself over to her instead. And she did. And she tortured him to death on the Stone Table, a sacrifice to make herself stronger."
"Aslan... came back. Killed the Witch. She hadn't accounted for some loophole in the Old Laws, and he had. But." Edmund swallows. "That doesn't mean he didn't die because of me. He talked to me, before that battle where he killed the Witch. Told me... By my grace, you live. For your sins, I died. Were it not for me you had been damned. Remember always what you owe. Live for me; go forth and sin no more. And for fifteen years, I did. I remembered what I owed. I lived for His grace."
"But when Tom was fixing me up for himself, something about that... came loose." He smiles tightly. "Stopped pretending to make sense. I stopped believing that it was a ten-year-old boy's fault that he was hurt by a grown woman, that it was his fault that his god lay down and died for him. I stopped being able to believe that. And I don't think it's a teenage girl's fault if she's not a perfect soldier. If she can't singlehandedly stop every bad thing that happens in the world, without anyone suffering for it."
He closes his eyes. "You don't have to forgive yourself," he says. "But - you don't have to forgive yourself to know that it's not your fault that you're not God. And if no one's told you that, then they hurt you. And that's not your fault either."
