After being rescued from the slavers, Illy had been living with the other harpies in their village, but she was troubled because her feathers were falling out and she couldn’t fly anymore. Illy only agreed to be examined by Glenn if Tisalia was present. He thought that was a little strange but agreed to it. Glenn tells her the reason that she can’t fly right now is that she’s molting, but Illy doesn’t agree with his diagnosis and runs off. Illy is convinced that she’s sick and calls Glenn a quack doctor. As Glenn observes her behavior, he notices a change occurring in her.
You aren't losing feathers 
because you're sick!
¡No pierdes plumas por estar enferma!
¡No pierdes plumas por estar enferma!
Vos plumes ne tombent pas
à cause d’une maladie,
Non stai perdendo piume perché sei malata!
Suas penas não caíram
por causa de uma doença!
Вы теряете перья не из-за болезни!
