Glenda The Not-So-Good Witch
A Story of One Power Hungry Witch
In America's song Tin Man one verse goes, "Oz never did give nothing to the Tin Man that he didn't already have," which is true. And Glenda the Good Witch was the one that caused all of Dorothy's problems in Oz.
If you start at the end of the movie when Glenda tells Dorothy she always had the power to go home and all she needed was to click the heels of the ruby slippers together, you just go, "Whoa!" Then you backtrack and see Glenda really isn't that good of a witch, after all.
Let's go back to when Dorothy lands in Oz and Glenda comes in her bubble. The Wicked Witch of the West wants to know who killed her sister, then she makes a dive for the ruby slippers and what does Glenda do? Why, she pops those shoes on Dorothy's feet, which is the beginning of all of Dorothy's problems. And who is it who sends Dorothy down the yellow brick road to visit the wizard with the promise he can help her get home? That's right. Not once does she mention to Dorothy she can use the ruby slippers to get home. Because there's nothing in it for Glenda if Dorothy goes home, right away.
The next time Glenda pops up to help she causes it to snow to kill the affect the poppies are causing Dorothy, preventing her from going to see the Wiz. Why does Glenda want Dorothy to go see Oz? Well, it isn't to help her to go home, as one initially assumes, until Glenda reveals Dorothy could have clicked her heels together to go home all along, only Glenda didn't tell her that, and instead sent her down the yellow brick road to face danger and possible death. So why does Glenda really want Dorothy to see the Wizard? One could surmise it's because he'll promise to help her go home if she promises to kill the Wicked Witch of the West. Which is exactly what he does.
So, Desperate Dorothy and her desperate friends go off on the mission to kill the witch. Dorothy gets kidnapped by the witch and her desperate friends rush to save her. In the process the Scarecrow gets set on fire. In all of this danger where is Glenda? Why, she's nowhere to be seen. It's up to Dorothy and her friends to save themselves and to kill the witch. After wards, they return to the Wizard to get what he promised them. The Tin Man, Scarecrow and Lion get a bunch of junk that you could find at a yard sale and the Wizard offers to take Dorothy home in a hot air balloon. She misses the balloon and Glenda just happens to show up just as talk is getting around to Dorothy staying forever. That's the last thing Glenda wants. Dorothy has served her purpose, now it's time to get this chick out of Oz. So she tells Dorothy she's always had the power to go home, and all she has to do is click her heels together. If Glenda is really a good witch, wouldn't she have told Dorothy that from the start?
Why does Glenda want Dorothy gone? Because Dorothy could be a threat to her power-grab for control of Oz. After Dorothy throws water on the witch, the witch's people are hailing her as a heroine for freeing them from the wicked witch. I imagine it's a sentiment that's felt throughout Oz, which is a major threat to Glenda's grab for ultimate power over Oz. That's why she needs to get this chick out of Oz and fast. By manipulating Dorothy to do her dirty work for her she's gotten rid of the Wicked Witch of the West and the Wizard, who both had their own pockets of power in Oz. All that remains is getting rid of the last threat to her total domination of Oz, the conquering heroine who vanquished the witch, Dorothy.
Don't be fooled by her fairytale princess like appearance with her magic wand and her pretty ball gown and perfectly coiffed hair-do. This is one manipulative power-hungry witch!
