“…Galinda is the character that changes. It’s all wrapped up, right there in her name. She starts out as Galinda, a snotty brat who cares too much about appearances, and ends up Glinda, a battered soul who still cares enough about appearances to never let us see how much pain she’s experienced. She quietly breaks down underneath a cockeyed grin. And she lives her life dealing with the consequences of her change and her choice, without the only friend that ever mattered… Glinda’s last notes in Wicked are in mourning, a lament for Elphaba, who can never let Glinda know she’s still singing in harmony with her.”
(Excerpt from “Wicked, and Glinda: the Musical’s Best Character”. Fan or not of Glinda, it’s an interesting read.)
This is like all my thoughts said with words. Truth.
