question (major plot hole?) spoiler
Unless I'm missing something, this is more than just a plot hole--it makes the whole film make no sense.
Why is it important to make it appear that Rachel is getting kicked out of the gang? The people she gets kicked out in front of are all together at the end of the movie, and were presumably all in on the con from the beginning, except for Dustin Hoffman's henchman Lupus, and (a) Lupus just gets killed at the end by the banker's guy, and (b) I don't see how it could've helped to try to make it seem to Lupus like Rachel was getting kicked out anyway, y'know, even if Lupus hadn't died when he did.
They should've wanted it to seem to the banker people like she was getting kicked out, not to Lupus.
This aspect of the plot, I think, makes no sense. Unless I'm missing something.
