Back home, Dexter picks up Harrison and takes the kid's temperature. Rita tells him her ex-husband's parents called and would like to take the kids to Disney World some weekend. Rita assures Dex Paul's folks are nice, it was Paul who was the "abusive black sheep" of the family. Plus, Rita says, it'll be good for Cody. She explains the fight and Cody's reasons for defending Dex. Rita doesn't appear to be at all suspicious, but she does say that Cody wants to quit Junior Sailors. Dexter totally doesn't care and goes to give Harrison a cool bath while Rita cooks dinner.
Deb and Angel are at her place, puzzling over the Christine situation -- both what she might know and how they should handle Quinn. Angel says they should "think outside the box," so we know Miami Metro is on the cutting edge of 1998 language. Deb's got something outside the box for him: Christine's the same height as the shooter. Angel's intrigued but neither knows WHY the hell she'd kill Lundy. He wants to do a DNA test, but they have nowhere near enough for a warrant. Deb's got an idea, though. One that lives outside a certain box.
Dexter bathes Harrison while DVO tortures him about Cody's fight -- the night he left the camp site WAS the night he killed Innocent Farrow, remember. For some reason, this sparks an idea: "Trinity's not the only one using his family as human shields."
Meanwhile, Quinn has officially blown his stack, having been told about Deb's suspicions. He screams that Christine didn't have anything to do with the shooting and accuses Dexter of being behind this. Man, Quinn has developed quite the hard-on for Dexter in such a short time. Deb rightly wonders what the shit Dexter has to do with this, and Quinn backs down like a chump. Deb, being kind, allows that she might be wrong about this, but Quinn's a good cop and he knows what it's like to have a hunch like this. Quinn's pissed Deb told Angel, making him look like an asshole. She tells him not to make it about him. Just help them get the DNA evidence, exonerate Christine, and then be free to shove it up Deb's ass whenever he likes. (Masuka just got phantom limb pain, wherever he is.)
