Seeing Dexter's car parked outside some bar, Deb mutters to herself about what a "lying little shit" he is before walking up to the door and seeing him, with his back to her, through the window. Her phone then rings - and he tells her he already ordered her a beer. Heh. She's both relieved and slightly peeved that this was part of the plan, but after the cute waitress gives Deb the promised drink, Dexter pulls out the Speltzer file. Deb remembers the case well, so Dexter tells her he thinks Speltzer is getting ready to kill again - he shaved his head that day, which fits his past alleged MO and signals that he's found his next victim. Deb wonders how Dexter would know that, so Dexter motions with his eyes, and Deb turns to see Speltzer in a chair flirting with the waitress. Deb, the pieces coming together quickly, gets to her feet and starts to berate Dexter, but he pulls her into the back and explains that he was trying to show her that there's some value to what he does. She's not buying it, Dexter - point out that you save her department money! Dexter goes on that he's taking trash off the streets, and when Deb tries to claim that the legal system works, Dexter replies, "If it worked as well as you think it does, I wouldn't be so busy."

He adds that it's for that reason that Harry structured his code the way he did, and if he takes Speltzer down now, no one else will have to die. Deb asks if he's really claiming that he does what he does to save lives, and Dexter manages both to do himself a credit and to sell himself short when he merely says that the end result is the same. Obviously, he does it first and foremost to satisfy the need in him, but even though he wouldn't say so himself, I think saving innocent lives has become meaningful to him. Deb asks if he's really going to commit murder based on a haircut, but Dexter says no - he hasn't even finished vetting Speltzer yet, and he won't kill him until he's absolutely sure he's guilty of murder. Deb, though, won't hear him: "This is done. And nothing better happen to that bald piece of shit over there." I'm only guessing about the bar scene in Miami, but I still feel like "Which one?" would be an appropriate response. Deb takes off, but DVO stays behind to let us know that he's not done with Speltzer...
