Just had a crazy prediction: Third Origin will make Wendy and Chelia older.


 * Edolas Wendy foreshadows this happening, given how old she is compared to normal Wendy.
 * Saying "good-bye to the magic girl" means "saying hello to the magic woman."
 * Not to mention Hiro seems to imply the Wendy/Mest pairing happening, so this could make that possible.

But I still doubt Wendy will lose her magic.
