Dexter : (voice over) Born in blood. Both of us. Harry was right. I thought I could change what I am, keep my family safe. But it doesn't matter what I do, what I choose, I'm what's wrong. This is fate.
Music: "Venus" by Frankie Avalon
Quinn: (to Dexter) Hey, it's the fucking Karate Kid.
The Karate Kid is a 1984 drama about a martial arts master, who agrees to teach a bullied boy Karate to show him that there is more to the martial art than fighting.
