"Luz," Amity breathed into her shoulder. "As long as it's with you, I don't care if the sky is falling."

As she sat on the porch of the Noceda household, drenched and shivering, her mind wasn't on the portal door she’d just lost. It was on the girl who had reached out for her in the chaos—the girl whose hand she was still holding.

Luz let out a sob that was half-laugh. King was gone. Eda was gone. The Boiling Isles were under the thumb of a child-god. But as she looked at Amity, standing there in the rain of a world she didn't know, Luz realized the "Lumity" moments weren't just memories to comfort her. They were the blueprint for how they were going to get back.

She remembered the , where Amity had first stepped out of her shadow to protect a "human." She remembered the glow of the Grom tree , pink petals falling as they danced a monsters' waltz, turning a nightmare into a masterpiece. She thought of the Eclipse Lake mines, where Amity had fought her own insecurities just to bring back a message for Luz, and the way it felt when Amity first called her "awesome girlfriend."

They stood there together—the human and the witch—two halves of a whole that the Collector couldn't break, ready to start the long walk toward a way home.
