As we know that it was Borden who sends Angier to Tesla when he asks the trick behind his magic. So, How did Borden knew that Tesla's machine could create a replica? Did he use Tesla's machine to create a replica(Fallon) or were they real time twin brothers?

  • He didn't know, that's the point. He wouldn't have sent him to Tesla anyway if he knew Tesla could build such a thing. But anyway, clear duplicate. – Napoleon Wilson Aug 18 '15 at 10:43
