Glinda and Elphaba-- the Wicked Witch-- have been friends since school and they originally were both going to go against the Wizard because of his cruelty to the Animals and unfair politics, except when they got to the Emerald City Glinda backed out. She wanted Elphaba to just go with the Wizard, because it was easier and it wouldn't get her hurt, but Elphaba was too proud and too focused on doing what was right to back down. So now they've gone their separate ways, but they still love each other and care about each other, even though they've chosen different paths-- one a socialite and the other a rebel.

There. Three sentences.
