3x2 - Where on Earth is Carmen Sandiego?

Carmen's thefts all seem to follow a Wizard of Oz theme. While chasing after Carmen, Zack and Ivy discover that Carmen was an orphan. They trail her to the Golden Gate Girls' School which is about to be torn down. The detectives recover all the stolen objects except for the orphanage. Zack and Ivy see this theft as being almost justified though because it was about to be torn down and was the only home Carmen ever knew.
