Dexter Season 7 Episode 12

La Guerta: (Deb holding a gun to Dexter) Shoot him, Deb. You have to end this. Shoot him.
Deb: (Dexter picks up a knife) Stop!
La Guerta: Do it, Debra, shoot him. Do it shoot him! This is not who you are. You're a cop; you're a good person. You're not like him. Put him down!
Dexter: It's true everything she said. You're a good person. It's okay.(Dexter puts the knife down) Do what you gotta do.

Harry: I think it's time to run Dexter. You knew one day it would come to this. That's always been the plan Dexter.
Dexter: That was before. It's not just Deb,
I don't want to run either.

Harry: Before? Before what?
Dexter: Before everything! Before I married Rita, before I had a son, before Deb knew who I was, before I fell in love.
Harry: What difference does any of that make?
Dexter: Somewhere along the line the fake life we created as a cover for me to kill became real. It's not fake to me anymore. I don't want to lose it. I'm going to stand my ground.

Hannah: (to Debra) You're the lieutenant of Homicide and you wear a big shiny badge and yet you know exactly what your brother is.

Hannah: (to Dexter)If you're worried I'm gonna tell people what you are then don't worry. Your secret is safe with me.

Dexter: I can't let Deb go down for what I've done.

Dexter: Sometimes it only takes a moment to reveal what we really are.

Doakes: (flashback)There's something off about you,Morgan! I should've seen it before. The fake smile the doughnuts-you don't even walk like a normal person. You glide like a...fuckin lizard on ice!

Dexter: It was a mistake to try and act human in front of Doakes. All I did was reveal how fake I was.

Dexter: We both knew it would come to this,one of us dead or behind bars.
Hannah: Except I always thought it would be you.

Dexter: I'm just a creep motherfucker.

Lt. Maria LaGuerta: (Interrogating Dexter Morgan) You framed Doakes! After I defended you against him. You betrayed me, this department, everybody around you.
Dexter Morgan: Is that what this is about; your desperate need to believe that James Doakes you knew, or thought you knew, wasn't a cold-blooded killer?
Lt. Maria LaGuerta: You don't have the right to speak his name.
Dexter Morgan: You're so hurt, angry, scared.
Lt. Maria LaGuerta: He's dead because of you.
Dexter Morgan: You were his partner, his lieutenant, his lover. But if you couldn't see what was right in front of your eyes, what does that say about you?
Lt. Maria LaGuerta: I swear to god, Dexter, I'm going to nail you to the wall for what you've done.
Sgt. Angel Batista: Maria.
Lt. Maria LaGuerta: To the wall!
Sgt. Angel Batista: Maria, that's enough!
