It's three in the morning in the Swan household, and someone is crying quietly in the living room.
This appears to be too complex a question for Elf-Bella. She blinks at him.
"Nope. I'm a magical device. I'm just human-shaped right now. I can be other shapes too."
"Oh." She closes her eyes, smiles a little ghost of a smile. "He's a demon. Also a dragon. You look like the demon part."
And then she falls out of whatever she did and she's back to being too lost to be frightened.
"They - they can't help it," she murmurs. "They try, they try not to - they can't help it."
"The Bond, that's how it works, they can't help it, I had to, I knew it would hurt me but we did what we had to do first, the world is safe," murmurs the elf.
"And now we're still Bonded and it's till I die and they can't stop," the elf whispers, "except when they sleep, and the dragon can sleep a thousand years but the demon can't, and when he's awake and I'm awake and neither of us concentrates - then - he reads my mind - and I can't think anymore, it hurts to think."
"He's asleep, now," she murmurs. "He might be able to sleep for a sennight. Sometimes he can. It used to help. It doesn't help as much anymore."
