Before the Curse
Zelena rips out the Scarecrow's brain. ("Our Decay")
The Scarecrow is kidnapped by a flying monkey and brought before the Wicked Witch of the West, who explains to him that she's working on a time travel spell and to complete it she needs a symbol of innocence, a symbol of courage, a symbol of love and a symbol of wisdom. She says how a symbol of innocence could be a baby for example, while a symbol of wisdom could be a brain - the Scarecrow's brain, to be exact. She prepares to try and rip it from his head, but Dorothy soon shows up and defends the helpless creature, chaperoning him to safety while she uses Toto to temporarily incapacitate the Wicked Witch. Zelena soon finds them in their hiding place though, and she rips the Scarecrow's brain out anyway and he drops to the floor dead. She keeps Dorothy alive though, wanting everyone to know that she failed so that she finally loses her greatest weapon of all: the love of the people. ("Our Decay")
