A foreign character who refuses to speak the language other characters are speaking on purpose.
Like Dokken on "Lost" or Finland on "Scandinavia and The World".
EDIT: Changed the odd name.
Five hats means that five tropers think it is ready to publish.
You are saying that you think this draft is ready to be published. That means the description is not ambiguous,
it doesn't duplicate an existing trope, there are at least three examples, and the title makes sense.
