Thinking about how for a good fifteen years Brian was just constantly following Dexter, monitoring and watching his every movement. Like there used to be a faint warmth to the air beyond just the Miami heat that was only for Dexter, at least before Dexter snuffed out.
I imagine somtimes Dexter catches himself missing the contours of it before he remembers he should know better. The revelation of it in the end just causes its abscence to make everything sharper, clearer, every noise, every movement, every breath. And Dexter knows it if anyone else tries to follow him. They don’t have the technique or the subtlety to cling onto every spare moment, let it linger in miserable tense silence without outright begging for attention. It’s sloppy and reckless and there’s a cold bite in the atmosphere that gives it away, brings a message to failed imitators, “Good luck trying to do that. Big brother already did it first. And better.”
