Kids say the darnedest things~
In the 1939 Wizard of Oz movie, we've seen Scarecrow getting torn up and patched back together, no big deal, right? And I've read plenty of fanfics where Scarecrow/Fiyero does some basic maintenance of having to patch himself back up, usually very gradually over time.
So, like, how does that all work? What does being a magically enchanted scarecrow entail? How much of him can be removed/replaced and it will still be him? How much of his original body, if any, needs to be present for his consciousness to transfer over???
Please point on the magic scarecrow where the sentience is located.
These are questions that are never meant to be thought about very hard, yet think about them very hard I shall.
And now so shall Fiyero, the poor bastard.
