In The Wizard of Oz (1939), when Dorothy arrives to Oz and she is introduced to Glinda and the Munchkins, the Wicked Witch of the West arrives and threatens her, but Glinda insinuates that she is powerless there (part of the script):
GLINDA Keep tight inside of them -- their magic must be very powerful, or she wouldn't want them so badly! WITCH You stay out of this, Glinda, or I'll fix you as well! GLINDA Oh, rubbish! You have no power here. Be gone, before somebody drops a house on you, too. WITCH Very well -- I'll bide my time -- and as for you, my fine lady, it's true, I can't attend to you here and now as I'd like, but just try to stay out of my way....
Here's the scene:
Forgive me if I'm not getting it correctly (English is not my first language), but what does Glinda mean with "You have no power here"? Is she literally implying that the Wicked Witch is powerless in some places of Oz/Munchkinland (something doubtful as she magically appeared and the Munchkins are scared to death of her)? Is it referring that she (Glinda) is more powerful than the Witch? What does she mean?
