Gwen Cooper: I know exactly what you are thinking, Jack Harkness, I know it: "She won't do this, not really, not my Gwen. No, Gwen she can't hurt me. Gwen loves me. She never hands me anywh" -- You know this is about my daughter. And I swear for her sake I will see you killed like a dog right in front of me if it means I get her back in my arms. Understood? Jack Harkness: Understood. And let me tell you: Now that I am mortal, I am going to hang on to this with everything I got. I love you, Gwen Cooper, but I will rip your skin from your skull before I let you take this away from me. Understood?! Gwen Cooper: Understood. I feel like I now know you better than I ever have before. Jack Harkness: Yeah. Right at the end.
