...so let's cut to a close-up of Julia Stiles's hands tearing open a packet of sugar, and given the pile of granules on the table in front of her she obviously needs to find a different way to occupy them. I'd suggest a smartphone and a Twitter app -- while hardly more productive, they at least won't attract ants.Dexter walks into the coffeehouse where Lumen is most thrillingly occupying her time, and when he joins her, she notes that he always looks disappointed when he sees her, like he was hoping to find an empty table. "Guilty," replies DVO, and I think they tend to overuse the VO for exposition quite often but I will never tire of mental hilarities like that one. Dexter tells Lumen that she should really consider his advice that she leave town and go home, but she asks, "If you had something horrible happen to you, could you just forget about it and move on?" He replies that he'd want to, and I assume he's talking about his childhood trauma but I'd like to imagine he's referring to the cheap technique the writers just used there. Surely Dexter is aware of the parallel -- in fact, especially given what he's going through with Harrison, it's exactly why he wants to divert her from the path of revenge -- so for the writers to give us this on-the-nose line for a One To Grow On moment is insulting. I mean, I know I'm coming from Mad Men, The Show Where Unnecessary Dialogue Goes To Die, but still.
Anyway, Lumen, after making sure that packet of sugar will never, ever hurt anyone again, asks Dexter to help her find those guys and kill them, as she saw him dispose of Boyd. "You knew what you were doing." Unfortunately, the arrival of the waitress stops Dexter from surveying her on the specifics ("Did you really think so? I thought I could have dragged out the death blow just maybe a second and a half longer"), and when she asks him if he'd like "the usual," I wonder about his choice of venue here, as it seems sloppy for him to be seen with sugar-packet-shredding Lumen by anyone who could pick him out of a lineup. When the waitress is gone, hopefully not to call Joey Quinn about the poster he dropped off earlier, Dexter tells Lumen in hushed tones that if she pursues this course of action, things will only get worse -- it will open up something inside her she'll regret ever learning was there. And while this is meant to frighten her in more than one way, as well it might given what she saw Dexter do, she kind of stupidly says she can't trust him, since she doesn't even know his last name.
