Downer Ending: Eddington escapes, Kassidy is arrested and Sisko is left alone again.
Explain, Explain... Oh, Crap!: Sisko starts asking why someone would want to draw him away from Deep Space 9 if the station wasn't going to be attacked, wondering what else would be going on there, and then pauses mid-sentence as he realizes it's about the industrial replicators.
Eddington: I know you. I was like you once, but then I opened my eyes. Open your eyes, Captain. Why is the Federation so obsessed with the Maquis? We've never harmed you. And yet we're constantly arrested and charged with terrorism. Starships chase us through the Badlands and our supporters are harassed and ridiculed. Why? Because we've left the Federation, and that's the one thing you can't accept. Nobody leaves paradise. Everyone should want to be in the Federation. Hell, you even want the Cardassians to join. You're only sending them replicators because one day they can take their "rightful place" on the Federation Council. You know, in some ways you're even worse than the Borg. At least they tell you about their plans for assimilation. You're more insidious. You assimilate people and they don't even know it.
The Mutiny: Eddington gets Sisko, Odo and most of the rest of the senior staff off-station, then stuns Kira with a phaser to take command and carry out his plan.
Not a Date: Garak says this about his upcoming holosuite time with Ziyal, but Quark knows better.
Not So Different: Eddington uses this as part of his Motive Rant, telling Sisko that the Federation is in some ways no different, if not worse than the Borg.
Oh Crap!: Kassidy's reaction to the Defiant de-cloaking in front of the Xhosa.
Papa Wolf: When Sisko confronts Kassidy about the Maquis' activities, his biggest worry is whether or not Jake might get hurt in an attack.
Unwitting Pawn: Eddington was just using Kassidy as a decoy so he could get away with the replicators headed for Cardassia.
