Asshole Victim: All of the Ancients who returned to Atlantis were exterminated by the Replicators, but they were such huge Jerkasses and Ungrateful Bastards that no one gives a damn.
Batman Gambit: "Plan-D"; McKay "accidentally" reveals their plan to sabotage the city's shield generators with C4 to the captive Woolsey and O'Neill, then "fails" to break them out of their cell. When they are mind-probed, the Replicators learn the plan and disarm the C4, overlooking the "real" sabotage; swapping the shield generator crystals for Anti-Replicator disruptor crystals.
Woolsey: That sounded like another explosion! O'Neill: Yes, yes it did. Woolsey: What does that mean? O'Neill: Something exploded.
Commuting on a Bus: Landry and O'Neill, at least in the context of Atlantis. While Landry and O'Neill will still appear in the final concurrent Season of SG-1 and the Direct-to-Video Movies, this episode marks their final crossover appearances on Atlantis.
O'Neill: So, am I to assume you are not surrounded by heavily-armed SG teams and young strapping Marines? Weir: You've got Col. Sheppard, Ronan, Teyla, McKay, myself and Dr. Beckett. O'Neill(sarcastically): Oh! Dr. Beckett, is it? Well I'm comforted.
Curse Cut Short: of the "another character interrupts" variety, when Jack O'Neill expresses disdain for McKay's proposed "Plan C:"
O'Neill: Sounds more like a Plan F, doesn't it? As in, 'We are totally—' McKay: If we can fight our way back to the bay...
Deadpan Snarker: Teyla after Woolsey expresses surprise that O’Neill figured out the plan but he didn’t.
O'Neill: I’ve seen Carter crack enough codes to know that McKay was faking the door thing. Woolsey: He was? I bought it completely. Teyla: I believe that was the point.
Guns Akimbo: Teyla, with the Anti-Replicator Guns.
Human Popsicle: Or Asuran Popsicle, anyway. Sheppard refers to Niam's retrieval as "picking up some frozen goods".
Leaning on the Fourth Wall: O'Neill's remarks about thinking of retirement, yet remaining involved in the community feels like Jack being a smartass to the Asurans and more about RDA speaking to the Stargate audience about having stepped from from SG-1 (yet still remaining a recurring character).
Kansas City Shuffle: The team lets O'Neill and Woolsey in on their plan to sabotage the city. However, the Asurans mind probe both of them and discover the plan in time to undo the sabotage... only to learn the lethal way that this was a cover for the actual plan, which involved rigging the shield generators to wipe out all Asurans in the city as soon as they activated. The team figured the Asurans would mind probe their captives, and deliberately fed them a false plan which the Asurans could stop without noticing the real one.
Mind Probe: Asurans have the exact same method the other human-form Replicators in Stargate SG-1 did, which is to literally stick their hands into someone's forehead and have their nanites extract the information directly (and painfully) from the victim's brain.
Woolsey: That was the worst thing I've ever experienced... O'Neill:(pats Woolsey on the back sympathetically) It gets worse.
Plot-Demanded Manual Mode: For some reason, the lever in the flooded control room that drains the also-flooded shuttle-bay has to be held down or else it automatically flips back and stops draining. O'Neill is quite displeased, as it means having to hold his breath for a very long time while in very cold water.
Reckless Gun Usage: Richard Woolsey violates numerous rules of gun safety while he's carrying his pistol. May or may not be justified because while he's largely just a bureaucrat, he's also a former NID agent who should at least know the basics.
Space Is Cold: Niam is coated in frost when they pull his body in from orbit.
This Is Gonna Suck: O'Neill when he realizes the Asurans are about to interrogate them, Replicator-style.
Time for Plan B: It takes Plan D before they get one that actually works.
Unspoken Plan Guarantee: Plan D is able to succeed because the audience (and, crucially, O'Neill and Woolsey) only learn up through Plan C.
