The Tin Man is the Reason Dorothy Got Left Behind in “The Wizard of Oz”

Remember towards the end of "The Wizard of Oz" when the Wizard takes off in his hot air balloon and leaves Dorothy behind? Well, the Tin Man did it and I have proof.

Watch this clip closely. When Dorothy jumps out of the basket to chase after Toto, you can see Tin Man undoing the rope that is keeping the balloon anchored.

I'm on to you Tin Man.
