There's a scene near the end of the Princess Bride where the evil Count Rugen confronts Fezzik, Inigo and Westley in the castle, and orders his guards, "kill the dark one and the giant, but leave the third for questioning."
One thing about those orders has been bothering me, and if I were one of those guards I would have survived by stopping to ask a question. Did Rugen mean to kill Westley, the "dark one" dressed in black, and question Inigo, the ringleader and (seeming) stranger to Rugen?
Or did he mean to kill Inigo, the one with dark hair, and question Westley?
I'm hoping there's more clarity in description or Rugen's thoughts in the book, but I do not have it.
