Is fiyero dumb in wicked the life and time of the wicked witch if the west?

In the book he meets an early demise when he is brutally murdered by The Wizard's secret police, presumably because he is affiliated with Elphaba, who is now a fugitive from The Wizard. Also in the book, he accidentally contributes to the Witches downfall. Before her accidental death by Dorothy she eventually realizes that Fiyero might not have died, but rather was changed into something else (the Scarecrow). Getting excited knowing that he was headed her way, she eagerly sent out many of her "workers" to pull off the face of the Scarecrow to reveal Fiyero.


In the movie, he is a careless, happy-go-lucky, kid who cares little about school. But when he meets Elphaba, he begins to understand that there is more to life than having fun and never thinking. He is transformed unwittingly into the Scarecrow by Elphaba as she saves him from a very painful, and ultimately fatal demise, by the Wizard's Guards. He helps Elphaba stage her death and runs away with her out of Oz to start a new life. Fiyero is the vehicle that makes a successful conclusion possible, by helping Elphaba escape.

Does this make him dumb? I do not think so.
