Dexter Season 7 Episode 12

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.
