Remember the part where Borden was accused of murder because he went downstairs and saw Angier (presumably a clone) drowning? Borden tried to save the drowning Angier. But, for the trick to work, the prestige is another Angier revealing himself onstage, with lots of people watching. So why was Borden accused of murder (downstairs) when the audience saw the prestige Angier onstage? OR did the prestige Angier even showed himself onstage? If not, how did the prestige Angier know NOT to appear to finish the act and frame Borden that night?

This is the reason why I wanted to watch it again. 3 days after and I still can't stop thinking about the film. I don't have a life these days :p
