I have been binge-watching Fringe and am now in Season 3. I have noticed that in every single episode, there is a moment when a long injection needle pushes into a vein, with no rhyme or reason, and all action is stopped while we watch this agonizing piercing with blood drops around it. To me, it appears like this is equivalent to addict-porn, someone getting vicarious pleasure from the sight of injections into veins--and it creeps me out. Now that I have seen it, I dread the moment that damn needle appears, and I wish it would stop.
Does anyone know the backstory on this obsession with needles?
