It's unclear what, exactly, is going on in Julia’s mind. There is, though, a clear double-meaning at play when she says, “It’s a blank,” since she’s both referring to the blank loaded in the gun and, perhaps, to her own state of mind—after all, she has just “blank[ed]” out by going into an absence seizure. More broadly, though, her morbid fascination with and fear of the gun suggests that she has significant trauma surrounding her hunting accident. When she says, “She’s hurting herself,” it’s unclear what she means, but the mysterious statement hints at the idea of internal, private suffering and agony—even if the nature of this suffering remains obscure and difficult to grasp.
