At the station, Matthews runs into Batista and is like, hey, Quinn did great on the exam, but Angie did even better, and you wouldn't want to derail your career as Lieutenant before it's even begun by fucking up this decision, but hey, totally your call! Batista's face: "Greeeeeat." That's its default setting, but still.
At Helena Metro, Dexter enters his office and gets the prints results – three matches, all of women reported missing, the latest of whom was taken two weeks ago, and we can tell from the frizzy hair that it's the girl who's currently thankfully unconscious in Yates' basement. DVO declares his intention to find out of Yates is The Brain Surgeon – by posing the question once Yates is on his table. He walks out into the common area, whereupon a downtrodden Batista calls an impromptu meeting on Norma Rivera; early indications point to the ex-boyfriend, but Batista, obviously still annoyed about the night before, cuts off Quinn's attempt to contribute, and after Masuka comes up to leak hormones all over the proceedings, Dexter heads out to take care of more personal business. It might not be enough to peg him as a killer, but I bet reviewing security footage of all the times Dexter has left the building during work hours would at least be enough to get him fired. Also, Batista tells Quinn to solve the Rivera case if he wants the promotion, which is a thing that might happen and people might care about.
A cute college-student girl finds Masuka, and with an endearing note of shyness, she cuts through his bullshit to tell him he might be her father – he was a sperm donor in college. Masuka gets predictably stunned and terrified, which in turn makes his daughter embarrassed and sad, but when she turns to go, she knocks over some lab equipment, and the noise seems to break the spell, and soon they're both doing that goony laugh he's known for, which I guess cements the idea that they're father and daughter. Funny, because I don't hate her, but there's time.
Elway steps into Deb's doorway to find her on the floor, case files spread out all over the place, and when he mildly points out they have filing cabinets, she explains that "this is kind of my process." Heh. Apparently, she's feeling better enough about herself in the wake of her last talk with Vogel that she's cutting short her time off, so he decides to welcome her back by ordering food and joining her. I hope he doesn't opt for steaks and beer, because that would just kill Dexter.
