Frightened about what had happened to his friend, the Tin Man pushed through the crowds of joyous people

Frightened about what had happened to his friend, the Tin Man pushed through the crowds of joyous people. He walked casually down the yellow brick road, calling out for the Scarecrow, but every time was left fruitless with a reply. He finally reached a fork in the road and came to a stop. He looked around and saw a huge cornfield beside him with an empty post and millions of crows. He glanced at the road itself and discovered something lying in the middle of the fork. He approached it to discover that it was the Scarecrow's hat. He picked up the old, tattered hat and discovered a note inside, which he unraveled and read quietly to himself…

Dear Fiyero, (What the…Fiyero? How does the Scarecrow know him and why does he have his mail?)

The plan worked!! Everyone in Oz believes me to be dead, but just to be safe, meet me at Kiamo Ko after the commotion begins; that way, no one will notice you're gone. Once the celebrating begins, sneak away from the scene and travel to the poppy fields. There, Chistry will pick you up and quickly transport you to Kiamo Ko. Once you arrive there, pound on the trap door 3 times so I know it's you, and I will activate "the door" (What could "the door" be? What in the world is Fiyero involved in?) Then we will together leave Oz and will search for means of the cure (Oh Oz, is he ill?). Till we meet again, my love…

Elphie

What the hell is happening? The Scarecrow knowing Fiyero! Fiyero and Elphaba together!! Elphaba alive!! There is only one way to find out my answers, and the answers lie in Kiamo Ko.
