I think that Angier - or his clone (more on this later) – did frame Borden like you suggested and did not appear on the balcony like he usually does with this trick. So everyone in the audience, who didn’t know about the drowning device, thought Borden killed him….see now my question is, was it Angier himself or his clone that cooked up this whole scheme? Ultimately it doesn’t matter what happens to Borden, but I am really wondering if the original Angier was the one who was killed or was it the clone when he uses Tesla’s machine the first time?? What do you think? is it the original Angier that lives on or his clones? You should definitely see it again because it made me love the movie even more after being able to figure out some things I missed the first time around.
