How we cite our quotes: All quotes are from The Sixth Sense.
Quote #1
VINCENT: Do you know why you're afraid when you're alone? I do. I do.
This is as close as Vincent gets to telling Malcolm what's really wrong with him. Is the film saying that if you don't express your deepest fears, it can eventually kill you? Hint: yes.
Quote #2
VINCENT: I was afraid! You told me I was having trouble coping with my parents' divorce. You were wrong. You were wrong. Now look at me! I don't want to be afraid no more.
Vincent decides that killing himself is the only way out of his misery. That motivates Malcolm to get Cole to talk about his fears so he won't meet the same fate. Cole already hates himself, so that's a realistic concern. Plus, Malcolm has seen the scratches on Cole's arms and probably suspects they're self-inflicted.
Quote #3
COLE: We were supposed to draw a picture. Anything we wanted. I drew a man. He got hurt in the neck by another man with a screwdriver.
MALCOLM: You saw that on TV, Cole?
COLE: Everyone got upset. They had a meeting. Mom started crying. I don't draw like that anymore.
MALCOLM: How do you draw now?
COLE: I draw people smiling, dogs running, rainbows. They don't have meetings about rainbows.
Cole's experience is scaring the heck out of everyone in his life because they don't know what's going on. Although they might be even more scared if he does tell them.
