In The Sixth Sense, Dr. Malcolm at one point tells Cole that he will not be able to help him and that he will contact someone else that can.
After this, Dr. Malcolm listens to the recordings of himself and Vincent talking. In the recordings Dr. Malcolm can hear "I don't want to die" being repeated over and over in Spanish.
This, somehow, makes Dr. Malcolm change his mind, but I do not understand why.
Prior to listening to the recordings Dr. Malcolm tells Cole that he does not believe that he can see dead people, after listening to it it may seem like Dr. Malcolm changed his mind.
