Wowee.
Signficant Event #1 - Dexter tries to shred his Mommy's photo, stops midway and saves the photo. Clever setup there - if Dexter had never touched Laura's file, the worst Deb could have learned is that Dexter is unwittingly related to the ITK. He could have denied knowledge of everything - Harry's affair, Laura being his mother, Brian being his brother.
By saving the photo after partially shredding it, he's establishing evidence that he knows who Laura is, and is trying to hide something - Harry's affair, that Brian was his brother, or both. That photo has now become a much more incendiary thing for Deb to discover than the original file.
Significant Event #2 - The inevitable happens, Dexter deliberately murders an innocent. He's done similar things in the past - the pedophile who never murdered anyone; Miguel's brother, even though that was self-defense. But this is the first time he's ritually slaughtered someone who turns out to be innocent.
Even scarier is the way it happened. I dunno about anyone else, but when Dex was in the kill room, the thought flashed into my head: "Hey! How does he know it wasn't the guy's assistant who murdered the models?" Followed by SQUICK and "Oh well, I sure hope it wasn't the assistant."
If I can think of that, why can't Dex? Because he isn't the perfectly objective serial killer anymore. Far from being the guy with no emotions, he is being ruled by his emotions. He doesn't like the creepy stuff the photographer does. He hears the word "rape," one of his hot-button issues (the other being anything to do with kids.) The guy says something sleazy to Deb (and far from the worst she's ever heard) and that sets him off even more. Maybe the guy's accent reminded him of Lila.
Dexter has gotten so completely compromised that he simply cannot continue to delude himself that he has the ice-cold objectivity needed to continue to kill according to the Code. I hope the writers really confront the consequences of this problem - the way I see it, Dexter has no choice but to stop killing. Yet that will put him and his loved ones at the mercy of the truly remorseless Dark Passenger. I have no idea how this problem can be resolved but I'm sure it will be fascinating!
