- Odo: I plan to investigate the Klingons, the Bajorans, Quark, the visiting Terrellians...
- Commander Sisko: You think Quark had something to do with this?
- Odo: I always investigate Quark.
- Chief O'Brien: You need to run a basilar arterial scan.
- Doctor Bashir: Why?
- Chief O'Brien: Because if you don't, I'm gonna die in less than five hours.
- Doctor Bashir: Who told you that?
- Chief O'Brien: You did. In the future.
- Doctor Bashir: Oh. Well, who am I to argue with me?
- Chief O'Brien: I really felt I was standing on the Promenade watching myself talking to Quark.
- Doctor Bashir: What was the conversation about?
- Chief O'Brien: He was complaining about some Klingons. He said they'd damaged two of his holosuites.
- Doctor Bashir: Well, you do have one problem. If all you can hallucinate about is Quark's maintenance problems you have a sadly deficient fantasy life.
- Odo: [after a lengthy derivation] The three Klingons now on the station are part of a covert strike force that reports directly to the Klingon High Council.
- Commander Sisko: Why didn't you just say so?
- Odo: Well, sometimes I have to remind you just how good I am.
- Commander Sisko: The Romulans generally prefer to sit back and pull the strings from a distance if they can.
- Major Kira: This is one puppet who doesn't like her strings pulled.
- Commander Sisko: And Major, when you're with the Romulans, try to be diplomatic.
- Major Kira: I'm always diplomatic!
- Major Kira: [in her interview with the Romulans] That's it! You can rip the cloaking device out of the Defiant right now, I am not answering any more questions! And I suggest you avoid asking Odo those questions, or you may just find yourself on the other side of that bulkhead floating home!
- Major Kira: ...And then... What's his name?
- Odo: Ruwon?
- Major Kira: Ruwon... started to insinuate that... you were...
- Odo: That I was what?
- Major Kira: Interested in me.
- Odo: [alarmed] He said that?
- Major Kira: Have you ever heard anything more...
- Odo: Ridiculous?
- Major Kira: Exactly!
- Odo: I think I can question them until the Romulan delegation leaves the station.
- Commander Sisko: Just be careful.
- Odo: Commander, there is no careful way to question a Klingon.
- Chief O'Brien: Trust me, Quark. Darts and bars go together like bacon and eggs.
- Quark: At least people order bacon and eggs.
- Chief O'Brien: I feel like someone just walked over my grave. I mean, I've had a few brushes with death in my career. But there was something about watching myself being killed, feeling my own neck for a pulse that wasn't there...
- Doctor Bashir: Well, could've been worse - could've been me.
- Chief O'Brien: You look pretty bad.
- Chief O'Brien: It's the radiation.
- Chief O'Brien: But if you feel bad, and you are my past self, shouldn't I feel bad too?
- Chief O'Brien: ...
- Chief O'Brien: ...
- Chief O'Brien, Chief O'Brien: I hate temporal mechanics!
