Outsides
"Fiyero, are you ashamed of my green skin?"
"Are you ashamed of my dark skin?"
"No, of course not!"
"Then why should I be ashamed of your green skin?"
"Because it's not natural! No one else in Oz has green skin!"
"Elphaba, your skin is lovely! Besides, it's not what's on the outside that counts! Your heart is what matters most!"
Fiyero always knew exactly what to say to make her feel better.
