At home, Dexter does not find a match for the print, and then his nanny Sonya (Maria Doyle Kennedy! Marie from the only Queer As Folk I'll ever acknowledge! Catherine of Aragon from The Tudors! How I love her!) comes out with a freshly-bathed Harrison and gets ready to go. Before she leaves, however, Dexter asks if she's ever noticed Harrison being aggressive, and she asks, "Aggressive? What do you mean?" Don't make me start in on you, honey. I'm having enough trouble with Dexter. Anyway, once Sonya has absorbed the concept of "aggression," which they of course do not have in Ireland, she tells Dexter that Harrison's a wonderfully gentle boy, and besides, even if he had a little dust-up it's nothing to worry about. "My brother used to bite people, bloody little cannibal. Now he's a vegetarian. Works for Greenpeace." Does...she actually think her brother would have eaten human flesh if he hadn't gone vegetarian? I feel like I'm getting confused about everything in this episode. What I'm not confused about, though, is the fact that it was in fact Lumen who left her print behind, as when he searches the DMV database he comes up with her name, like, DURR, Dexter. A hilarious little throwaway tidbit on her license, however, is that she's an organ donor, like, make sure you make a note of that if you end up having to stab her to death, Dex!

Dexter goes to Lumen's motel room, and I know he paid it current last time but I don't know why that means it would be untouched at this point, but regardless, after he works some lock mojo, inside he finds a big old Wall of Psycho, with clippings and photos and notes written in CUCKOO SPEAK and the word "RAPE" in about four thousand different places, and Dexter's face is like, "This is a bit crazier than I usually take my crazy, thanks." Still, from this, regardless if there's actually a connection to Boyd, which I still have not heard Lumen actually say, it does seem like she was telling the truth about some other terrible stuff having happened to her. On the other hand, when did she have time to do all this? Just since Dexter rescued her? Seems like a lot of work even for the sufficiently motivated. Anyway, in all the sensory overload you might have missed it, but from the way it's shot I think the paper with three locations on it -- "Venetian Causeway, Julia Tuttle Causeway, North Bay Village" might be significant. We also get a quick focus on a picture of some dude with a beard, and then Harry pops up and literally asks Dexter if all this work seems like the product of a stable mind, like, I know you're being sarcastic but I think I'm still going to have to respond NO. Dexter notices a makeshift bed in the closet and theorizes that Lumen slept in there because "a closet was the only place she felt safe from them," and if she's this nuts I'm surprised she didn't do a Fuentes on Dexter last week instead of just scratching him in the arm. Anyway, Harry urgently uses sock puppets and semaphore flags to try to convey the fact that Lumen has lost her ever-loving mind, but Dexter is too busy with the missing letter he's just located from Boyd's onetime cellmate "Robert Brunner," who wrote that he's getting out on parole and needs a place to "sleap." If there's also any talk of them revisiting "aneal seax," Dexter demurely omits that part. Harry tells Dexter that Lumen's path isn't going to end well, like, thanks for keeping up after you've been on the show for five years, Harry, and then adds that Lumen is going to bring Dexter down. Dexter takes a long moment to contemplate that...
