Status Transfer, Emotional Switch
In this scene the two actors will be assigned contrasting emotions. At some point in the scene they must switch the emotions from one player to the other.
The emotions must be contrasting (love, and hate), and the players must make strong choices in the beginning of the scene. The transition is best appreciated if it is done subtley and the transfer is somehow justified within the context of the scene.
This can be done with status (high versus low), and the players must make a switch in status within the scene. Any of the endowments can be switched: political beliefs, animals, appliances, vehicle types, etc.
