The movie now you see me, what the hell is the ending suppose to be?

The four magicians have accomplished their tasks successfully like the FBI agent (played by Mark Ruffalo had asked). The FBI agent was in fact the one who hired the magicians to help him take revenge for his father, also a magician who died while performing a trick. The four horsemen agreed to help him because of The Eye, presumably some sort of secret society only for the most talented and distinguied of magicians. The Eye had remained only hearsay and a legend up till then, but at the end the four horsemen realised that it was real an they joined it by jumping into that carousel thing.
