Critical error? or Don't worry about it?

Wait a minute something really important was covered here!! did the wicked witch actually say that?
Well ....I was in a hurry when I wrote that sentence, the wife was calling!! But the Wicked Witch did say about getting the ruby slippers off of Dorothy's feet, "These things must be done delicately!"....just like installing the pins while the transmission is dangling just behind the engine.
See bottom of script:

Dorothy: [Toto is held hostage by the Witch and one of her monkeys] What are you gonna do to my dog? Give him back to me!
Wicked Witch of the West: All in good time, my little pretty. All in good time.
Dorothy: Oh, please give me back my dog?
Wicked Witch of the West: Certainly. Certainly. When you give me those slippers.
Dorothy: But, The Good Witch of the North told me not to.
Wicked Witch of the West: Very well.
[to her flying monkey]
Wicked Witch of the West: Throw that basket into the river and drown him!
Dorothy: No, no, no! Here... You can have your old slippers. But, give me back Toto!
Wicked Witch of the West: That's a good little girl. I know you'd see reason!
[the Witch stoops to steal the shoes. But, fire burns Dorothy's toes and the Witch's hands. she reacts in pain]
Wicked Witch of the West: Ohhhh!
Dorothy: I'm sorry! I didn't do it. Can I still have my dog?
Wicked Witch of the West: No! Fool that I am! I should have remembered! Those slippers will never come off as long as you're alive. But that's not what's worrying me. It's how to do it. These things must be done delicately or you hurt the spell.
