02. Reliquary (Martha Wells)

John: McKay, what do you think?
Rodney: I think you should stop exchanging facetious random babble with Ford and try to use your obviously overrated gene to make this damn thing work.

John: Ford's in charge.
Rodney: Oh, no kidding. I'll try not to stage a coup while you're gone.

04. Halcyon (James Swallow)

Rodney: Snow. I don't perform well in the cold, Colonel. I get the ah - The sniffles.
John: Then take a scarf.

Rodney: John?
John: Rodney, I don't want to appear like I'm uncaring or disinterested in your complaints, but I am, so that's how it comes out.

Rodney: Okay, sure, we do have a patch that says Atlantis on it, and maybe we might want to keep where we come from a secret from some people, but who in the Pegasus Galaxy can even read it? It don't see the point.
John: You're forgetting one thing, Rodney.
Rodney: And what's that?
John: For all we know, on Halcyon a red maple leaf on a white background could be a symbol for 'please eat me alive' in their native language.

Rodney: True, but you have to remember that the majority of the Wraith have been dormant, although that's changed recently thanks to certain people.
John: Are you ever gonna let me forget about that? I don't keep reminding you about that planet you blew up.

07. Casualties of War (Sonny Whitelaw & Elizabeth Christensen)

John: I gotta say, nothing makes a guy appreciate his position on the Atlantis food chain like being ordered to hold a flashlight.
Rodney: Many people with more postgraduate degrees than you have gotten me coffee, Colonel Uppity.

John: You're saying we blew a fuse?
Rodney: Yes, that's exactly what I'm saying, except my version wasn't painfully simplistic and utterly superfluous to the point.

10. Nightfall (James Swallow)

John: But you can disarm it, right? I mean, you're Rodney McKay, genius guy. You do this sort of thing all the time. You thrive on it!
Rodney: The thing I thrive on the most is not being reduced to my component atoms.

12. Dead End (Chris Wraight)

John: OK, remind me again why I agreed to come down here with you?
Rodney: Because your devotion to duty knows no bounds, and I need your impeccable scientific credentials. That, or Zelenka's laid-up sick and you're the next best thing.

John: Quit complaining. You're the one that started all of this.
Rodney: I'm so glad you're here to point these things out.

John: But stay sharp, we don't know what we're getting into here.
Rodney: Oh I think we do. And it begins with a Capital T.

John: Looks pretty bad.
Rodney: Well, that's an astute comment, if I ever heard one. Why don't you take over the repairs? Perhaps I could hand you a wrench from time to time and make the coffee?

John: Nothing. Nada. Zilch. This baby's going nowhere.
Rodney: This endless positivity is really helping. Honestly, you should think about becoming a motivational speaker or something.

John: You've started looking a little... crazy-eyed.
Rodney: You think so? God, that'll be the cold. I mean, my eyes are my best feature. Apart from my hair. And Jeannie always said I had a cute smile.

Rodney: I'm going to have to do the whole thing with a few rolls of duct-tape and a hair-dryer.
John: You brought a hair-dryer?

Rodney: Let's not do that again: it's far too gribbly.
John: Gribbly?
Rodney: Technical term.

13. Hunt and Run (Aaron Rosenberg)

He tried to put himself in Ronon's shoes - and failed miserably. So he tried to think like Sheppard instead. That was a little easier, though horribly limiting.
