Moana didn't speak but she opened her palm a little wider. She knew that Amy wouldn't do anything to the Heart and at this point, Moana knew that she couldn't bring the hearts glow back to it. Now it was just an ordinary stone but as Amy lifted it Moana felt it's weight pull off her palm as if it would have crushed her had she held it a moment longer.

"It began to go out a few weeks ago." She confessed in a soft voice. "I thought I could find out why or bring it back but… I couldn't."

The heart was dormant or dead. Moana didn't know for sure.
