Well, here's a little more (I'm posting at night again)
In the Wizard's chamber, Madame Morrible was pacing and muttering under her breath, while the Wizard sat in his armchair near the blazing fireplace. He watched the dancingflames as he gripped a green, glass bottle. This is the reason she was born green he thought, gripping the bottle even tighter.I should have know she was my daughter when I had first seen her. Regardless of the green skin, she looks so much like her mother. "I must get her back" he said out loud. Madame Morrible stopped her pacing and muttering and looked up at the back of his armchair. "I came back to take what rightfully belongs to me. Well, she certainly qualifies as mine. She is my flesh and blood." He turns his face around to look at Madame Morrible "And I do not want her harmed in any way! Is that clear?"
"But, sir, she is an enemy!She must be given an enemy's punishment of death! Besides, when the Gale Force finds her, they shall have to restrain her, and if I know Elphaba, she will not give in without a fight. They won't have any choice but to harm her at least a bit."
"I won't have my only child harmed! Traitor or not!" he said standing up, holding the bottle tight in his fist "I never had the chance to love her as a father, and I plan to make at least a little up to her." he brought his eyes down to the floor "What kind of father would I be if I killed my own daughter?"
"And what kind of ruler would you be if you didn't kill your own enemy?"Madame Morrible shot back. He looked up at her, glaring. "The people will turn against you if you do not get rid of her...for good." she continued. TheWizard gave her a cunning grin.
"That is why, my dear Madame, I choose not to tell the people that she is still alive.Once I have her back, I plan to keep her here away from the rest of Oz, where she will be safe. I shall explain to the guards that I want to use her for her powers,and that they are not to tell a soul about her existence until she agrees to join me." he lowered his eyes again "In which I know she never would."
"Very well, Your Ozness. If that is what you wish.," Madame Morrible said, still looking a bit disapproving "But how will you prevent the Gale Force from hurting her when she is captured? You know they must. She is a strong fighter." The Wizard looked back up and grinned again
"Why do you think I kept Miss Glinda the Good alive? When Elphaba finds out what has happened to her (and I know she will, she is a very clever girl), I'm sure that she will attempt to free her imprisoned friend. I have ordered my best guards to stay hidden and let anyone go inside the prison, but to never let them come out unless they are properly identified; if the person looks suspicious, they are to close off all means of escape and alert me immediatly.So, when my determined little emerald-girl steps inside to save her dear friend and is recognized by the guards, she will be trapped until I come and get her." Madame Morrible raised an eyebrow anddisplayed agrin to match the Wizard's.
"So, you are using Miss Glinda as bait to catch her. But what do you plan to do with Miss Glinda afterwards?"
"Use her as leverage." the Wizard said shrugging "I'll threaten to destroy her if Elphaba ever tries to run away."
"And if Miss Elphaba succeeds in rescuing Miss Glinda?"
"She won't." the Wizard said, turning once again towards the fire "She mustn't!"
