Carter: They said it isn't either one of us. We just have to keep trying.
Ambassador Joseph Faxon (Christopher Cousins): I don't mind trying. I just, I thought we'd be working on our second child by now.
Carter: Me too.

Joe: Maybe we should get a second opinion.
Carter: The Aschen are hundreds of years more advanced in this than we are.

Carter: I'm fine, right?
Dr. Fraiser: Sam, I don't know how the Aschen doctor could have missed it, and frankly I don't think he possibly could have.
Carter: What?
Dr. Fraiser: You can't have children.

Jackson: Guys, I think it would be public knowledge if something this catastrophic was happening to the entire population.
Carter: Would it? I mean the Aschen can convert planets into stars. You don't think they could control the media if they wanted to?
Jackson: Assuming the Aschen can keep something this big a secret, it's been ten years. Why now?
Carter: We were completely taken in. This way they didn't have to fire a shot. I mean it's slow, methodical. Painless.

Jackson: We have to think of something else.
Carter: Like what?
Jackson: I don't know. Contact the Tollan. Find the survivors of the Tok'ra. I mean there have to be some out there. Teal'c what about the Jaffa?
Teal'c: Very few remain loyal to the Tauri since the wars end. There are few symbiotes available for implantation.
Carter: We don't even control the Stargate. God, what have we done? This morning we were celebrating.
Jackson: Now I wish we could take it all back.

Dr. Fraiser: We are considering changing the lives of the entire human race on earth. Do we have that right?
Carter: If we don't, then we will live to see the end of the entire human race.

Carter: So this is the place you kept threatening to take me. It's good to see you, sir.
O'Neill: I'm retired, Carter. Lose the sir.

O'Neill: Let me tell you something, Carter. You want to erase your mistakes? That's your business. My conscience is clear. I warned everybody. I threw up a red flag and everybody—including you—shut me down.
Carter: I'm asking you to put that behind us.
O'Neill: You're not happy with the way things turned out? Sorry to hear that. Personally, I like things the way they are. No more saving the world, just a nice pond with no pesky fish in it. And the single most pressing issue in my life is whether or not to get a dog. There are a lot of pros and cons to that subject.
Carter: Jack, we're talking about the future of the human race.
O'Neill: So was I.
Carter: We're doing this.
O'Neill: Let me know how it turns out.

Tour Guide: And these people comprise the famous SG-1. Arguably the most important, although not my personal favorite, team of the entire command.

Carter: So. When did you decide against getting a dog?
O'Neill: I'm still thinking about it.

A note comes through the Stargate
Hammond: What is it?
Jackson: Well?
O'Neill: You tell me.
Jackson: “Under no circumstances go to P4C-970. Colonel Jack O'Neill.” That looks like your handwriting.
O'Neill: It is my handwriting. And it's my signature.
Teal'c: Though you sent no such note?
O'Neill: Nope.
Fraiser: Sir, may I? {she takes the note} That looks like blood, sir.
Hammond: Have it analyzed.
O'Neill: General, wasn't 970 on our mission list?
Hammond: It was. Not anymore. I'm not taking any chances. I want P4C-970 removed from the dialing computer immediately. Dismissed.
Carter: I wonder why you sent it. I wonder when.
O'Neill: Yeah. Gotta wonder.
