Which element for WICKED was used for the first time in the London version of the musical and the creative team liked it so much that they put it into the set design for the NEW YORK Broadway show?

The scene of Elphaba and Fiyero's first meeting

Explanation:

When the musical Wicked was performed in London for the first time in 2006. at the West End, production changed some details to suit the local audience. There were changes to the dialogue and accent, like the line “fix your hair” was rewritten to “do your hair”.

The change that was a bit bigger, and that was later included in Broadway production was the scene of Elphaba’s arrival at Shi*z University. In the London production, Elphaba met Fiyero the first time he arrived at the university. There are some new dialogues here that set the tone of their relationship for later. This scene is now included in the New York production.
