"The lion was the seal," Jin said. "It didn't hold the doors shut with strength. As long as it sat in front of them, that thing couldn't get out. That's what a haetae is. It's a guardian. It keeps the evil things on the other side of the door."
Behind him, the doors shook. Dust rained down from the roof.
"We killed it," he went on, "so now there's nothing sitting there. But you turned into it once already. If you can become it all the way, not just the scales and the stamp, but whatever it is that makes it a guardian, then maybe you can do what it did."
Yujin stared at him. "You want me to sit in front of the door."
"I want you to be the thing that sits in front of the door," Jin said. "Long enough for us to shut it for good and get out of here."
