What do you think Borden wrote on the note Caldlow tore up? *SPOILERS*
In their meeting at the prison at the end, Freddy offers Angier a folded up note: "Here, that's what you're after. That's what this is about. Take it."
Angier: "Your secret?"
Freddy: "Yeah."
Angier then tears it up without looking at it: "You always were the better magician, we both know that. But whatever your secret was, you have to agree, mine is better."
An incredibly powerful moment, but it raises two questions:
(1) Wouldn't Angier still be curious to know the secret? and, more interestingly to me,
(2) What did Freddy write on the note? The truth, or another ruse like "Tesla"?
