At the end of the movie, before leaving Angier behind, Cutter told (not exact quotes):
(Cutter) Once I told you a sailor who onced described drowning to me. Remember?
(Angier) Yes you said it was like going home!
(Cutter) I was lying. He said it was agony.
I can understand why Cutter lied (to console Angier for his wife's death) But could not understand why did he need to tell the truth at the end?
Was it because he knew Borden (twin) was going to kill him and that before death Angier must know the truth?
