The End
People still ask Harron and Turner if Batemans murders really happened, or take place in his imagination.
Mary Harron: I would never answer that. As Quentin Tarantino says, If I tell you that, I take this movie away from you. I will say theres a moment where it becomes less realistic, and thats the moment when the ATM says Feed Me a Stray Cat.

So in the first place the director/co-writer and other co-writer don't say the same thing about this. Either way, I more subscribe to an "author is dead" approach to analyzing works. What Guineverre Turner claims about the process of writing the scenes does not necessarily hold up to the textual evidence, and how she felt in developing those scenes did not necessarily translate to how those scenes resulted, and the direction that was taken to actually create those scenes past the initial text. For example, right after your quote cuts off she says,

Like he shoots at a cop car, and it just bursts into flames, and she just directed him to look at the gun like, Hmmm, how did that happen?

There's more to a movie getting made than the screenplay.

The significance is the reveal to Jean.

But my point is, Jean no longer holds relevance to the story at that point. Patrick's interpersonal life doesn't matter in the last minutes of the movie.
