Glinda was changed. She knew it herself.... She had invented a nonsense disease for Ama Clutch, and Ama Clutch had come down with it. Was this proof of an inherent talent of sorcery? (22.214.171.124)
Glinda is dealing with her guilt and her growing mistrust of Madame Morrible.
She has also ditched her old "friends" and now mainly socializes with Elphaba, who is becoming a true friend.
Elphaba explains Nessa and her family history to Glinda.
We learn the details behind Melena's death after Elphaba's brother Shell was born in Quadling Country.
We also learn that Turtle Heart is dead:
The crowd, incited by some rabble-rousing faithers and a prophetic clock, fell on him and killed him. (126.96.36.199)
Elphaba talks about her hard childhood in Quadling Country. Frex worked as a missionary and Elphaba witnessed how the Wizard's troops came to mine for rubies and rounded up the Quadlings into "settlement camps" and killed them.
Glinda doesn't care about politics and wants to hear about Elphaba's siblings:
"Nessarose is a strong-willed semi-invalid" said Elphaba. "She's very smart, and thinks she is holy." (188.8.131.52)
Nessa sounds like the life of the party. Shell is notably not deformed.
Elphaba notes that Nessa is their father's favorite. We're sure that little detail won't cause any problems at all in the future.
Glinda is not a huge fan of Nessarose. She finds her overly demanding and obnoxious.
Glinda is majoring in Sorcery (which she has a natural talent for) and she enjoys her classes with Miss Greyling.
Over lunch, Glinda, Elphaba, and Nessa discuss religion and magic.
Elphaba argues that magic is nothing but tricks and illusions.
After Elphaba calls sorcery "trivial." Glinda tries to levitate Elphaba's sandwich and ends up blowing it up instead.
Elphaba laughs and says she doesn't believe in religion or magic. Nessa is offended by her sister's self-proclaimed atheism.
We have a feeling Nessa is the type who would go to a party in order to lecture everyone against partying.
