How we cite our quotes: All quotes are from The Sixth Sense.
Quote #1
ANNA: Finally, someone is recognizing the sacrifices you've made—that you have put everything second, including me, for those families that they're talking about.
Seems like Anna's making a dig here, since we (and Malcolm) assume she means that Malcolm has put her second in order to help other families. But really, it doesn't look like she's holding it against him too much, since things start getting romantic between them right after.
Quote #2
[Written in Malcolm's writing in Vincent's chart: Parental status: divorced.]
[Written in Malcolm's writing in Cole's chart: Parental status: divorced.]
These two scenes show us two things: that Malcolm sees the cases of Vincent and Cole as similar, and that a kid being from a divorced family is something that is worth noting. As it turns out, Malcolm erroneously attributed Vincent's emotional problems to his parents' divorce.
Quote #3
MALCOLM: I'm not supposed to talk about stuff like that. Once upon a time, there was this person named Malcolm. He worked with children. He loved it. He loved it more than anything else. And then one night, he found out that he made a mistake with one of them. He couldn't help that one. And he can't stop thinking about it. He can't forget. Ever since then, things have been different. He's not the same person that he used to be, and his wife doesn't like the person that he's become. They barely speak anymore—they're like strangers.
Cole has turned the tables on Malcolm and is asking him personal questions about why he seems out of sorts. Malcolm acknowledges that he shouldn't be talking about stuff like that with a patient, but he does anyway by telling Cole a "story." He's extremely upset about how his relationship with his wife has deteriorated since the incident with Vincent, but he's unclear on how to move forward. The distance between Malcolm and his wife mirrors that between Cole and his Mom. Except for the inconvenient fact that Malcolm is dead.
