Quote #4
He thought of the Bowie girl—no, McDougall, her name was McDougall now—saying in her breathy little voice that she had hit her baby and when he asked how often, he could sense (could almost hear) the wheels turning in her mind, making a dozen times five, or a hundred a dozen. Sad excuse for a human being. (6.295)
Again, Sandy McDougall has an evil secret, which according to the novel makes her a sad excuse for a human being. And soon she'll literally be a sad excuse for a human being… in that she'll be a vampire. So everything works out on a symbolic level.
Quote #5
"Matt, do you know what's going to happen to you if you even let out a whisper of what you've told me?" (8.115)
Ben is telling Matt he needs to lie to the authorities or people will think he's insane. The vampire hunters actually end up telling a lot of whoppers to keep the police off their backs. It's almost like they're in cahoots with the vampires, helping them hide so that the plot can rush along.
Quote #6
… George Middler had a suitcase full of silk slips and bras and panties and stockings and that he sometimes pulls down the shades of his apartment over the hardware store and locks the door with both the bolt and the chain and then… he falls to his knees and masturbates. (10.10)
Vampires often symbolize lust (see "Themes: Lust"), and so many of the secrets in this book are sexual secrets. The book says little about George Middler except that he dresses in women's clothing secretly—and later it's suggested that he's a homosexual and a pedophile. Linking homosexuality and cross-dressing to evil, vampires, and pedophilia wanders uncomfortably close to homophobia, though it's worth mentioning that in 1986's It, King explicitly condemns homophobia.
