How is it that Mulder and Spender can have the same DNA if they are only half brothers. My understanding is that only twins will have the same DNA.
In any event, Spender was a FBI agent as much as Mulder was. If they have the same DNA, the system should have logged 2 hits instead of just 1 hit on Mulder.
Reyes: Dana... the room's all fresh for you. I threw out all the old bedding and bought some brand-new stuff, okay?
Scully: Thank you.
Reyes: I know it's impossible to stop thinking about what he said, about William... but it's all lies, Dana, and you were the one who proved it.
Scully: And how should I prove it now? By insisting that I can protect him... only to learn too late that I can't?
Reyes: You say it as if you have a choice.
Scully: He didn't have a choice to come into this life. I don't have a choice about what he is or was... but I do have a choice about the life my son will have... And shouldn't I choose that he never have to be afraid of anyone or anything? And can I ever really even promise him that?
Reyes: But who can?
Scully: I have seen my share of the hideous, of the disgusting and the repellent, but you, Sir, are the most perfect expression I will ever see of all that is vile and hateful in life.
Jeffrey Spender: That may well be, but for a moment, you believed it - that I was him.
Scully: I never believed it.
Jeffrey Spender: You wanted to believe.
Scully: You are as false as your face. I bet you wish night and day that that bullet that was meant to kill you had succeeded.
Scully: Where's Dr Edwards?
Dr Newman: I'm Dr Newman. I'm going to take your baby.
Scully: He's been injected with something.
Dr Newman: We're taking him to trauma. Airways are open. Lungs are clear. Heart rate slightly elevated. Skin is warm. Nondiaphoretic.
Reyes: I spoke to another doctor, a woman - Dr Edwards.
Dr Edwards: I'm Whitney Edwards. Agent Reyes?
Reyes: Yes. This is Dana Scully.
Dr Edwards: Do we have any idea what he's been injected with?
Scully: I've no idea. I don't know. I don't know.
Dr Edwards: We're going to run some tests on him...
Scully: I'm a medical doctor, okay? Can I...
Dr Edwards: Good. Then you know what this is all about. You just need to sit tight for me and let us do our job.
Scully: Agent Reyes.
Reyes: Agent Scully.
Scully: Do we know who he is?
Reyes: He says his name is Miller, but he has no identification on him. Beyond that, we don't know a lot.
Scully: Why are the lights off?
Reyes: He wouldn't speak with them on.
Scully: What do you mean?
Reyes: If you saw him in the light, you'd understand. Something's wrong with his face. He's been severely burned - by fire or maybe acid.
Scully: And he says he knows me?
Reyes: And that he's afraid. A victim of what he calls the alien conspiracy.
Spender: It'll never be over. They'll always know what he was. They'll never accept what he is.
Scully: Well, I can protect him.
Spender: And if you can't? Look at me, what they did. Is this what you want for your son?
Doggett: (To Spender) I don't care who the hell you are!! If anything happens to that baby, I will personally take you out.
The time stamp on the first scene in the X-Files office, with Doggett doing push-ups, is 11:21 pm. Chris Carter's wife's birthday is the 21st November.
Although David Duchovny is uncredited in this episode, he is seen for a split second, by Scully when she is examining the disfigured man, soon to be named Jeffery Spender (Mulder's half-brother), when she looks in his eyes.
Subtle hint that the Cigarette Smoking Man is still alive? Spender claims that he is seeking revenge on his father by depriving "them" of super-William: not something you typically do if the target of your revenge is...well, dead.
Near the beginning, as Scully is in her car with William, she is singing "Joy to the World" to William, the same song she sang to Mulder while they were stuck in the forest in the Season 5 episode, 'Detour'.
