Dr. Rodney McKay: You have no idea which way to go, do you?
Maj. John Sheppard: Just trying to get my bearings.
Dr. Rodney McKay: Translation: "I'm lost. "
Maj. John Sheppard: "You're going to be fine"?"Beckett'll figure this out"? You really suck at the whole "bedside manner" thing.
Elizabeth Weir, Ph. D.: I know. I'm sorry.
Maj. John Sheppard: But I appreciate the effort.
Maj. Lorne: I was hoping Lt. Ford would recognize a friendly face and turn himself in.
Dr. Rodney McKay: You mean me?
Maj. Lorne: Well, you were friends, weren't you?
Dr. Rodney McKay: Oh yeah, when we weren't out on harrowing missions, we used to hang out together. I'd share my dreams of self-sustaining fusion, he would talk about how you could sever a man's torso with a P-90.
Teyla Emmagan: Do you kill all your violent criminals on Earth?
Dr. Rodney McKay: Certain countries, yes.
Maj. John Sheppard: Do we need to get into this right now?
Dr. Rodney McKay: I'm not sure I can fix this.
Dr. Peter Grodin: You can fix anything.
Dr. Rodney McKay: Who told you that?
Dr. Peter Grodin: You did. On several occasions.
Dr. Rodney McKay: I'm sorry. It's just... I react to certain doom in a certain way. It's a bad habit.
Eldon: The technology on this ship is far more advanced than the Olesians'.
Dr. Rodney McKay: How ironic, then, to have been shot down by the cast of "Braveheart."
Elizabeth Weir, Ph. D.: Carson?
Carson Beckett M. D.: Elizabeth.
Elizabeth Weir, Ph. D.: How are you doing?
Carson Beckett M. D.: Oh, just peachy, thanks. You?
Elizabeth Weir, Ph. D.: I'm sorry to put you in this position, but you're the only one besides Colonel Sheppard and General O'Neill who've actually fired a drone from that chair.
Carson Beckett M. D.: Ironically, they're the two people I nearly killed when I did that.
Dr. Rodney McKay: Well, thank God! You were the only... I thought I was gonna.
Teyla Emmagan: I thought you were very brave.
Dr. Rodney McKay: Really?
Elizabeth Weir, Ph. D.: You were right.
Carson Beckett M. D.: Lovely... About what?
Elizabeth Weir, Ph. D.: Your theory of the Wraith evolving after the Ancients arrived in the Pegasus Galaxy.
Dr. Rodney McKay: You've got to be kidding me.
Dr. Zelenka: Pay up.
Maj. John Sheppard: You know, Rodney, you were great back there. Wanna take the stick?
Dr. Rodney McKay: Really?
Maj. John Sheppard: No.
Commander Acastus Kolya: My name is Commander Kolya.
Maj. John Sheppard: "Kolya", that's a difficult name to pronounce. Is that a first name or a last name?
Maj. John Sheppard: Well, leave it to convicts to know the best way to tie people up.
Marin: The island is a penal colony. The prisoners usually don't cause much trouble, as long as you don't try to land there.
Dr. Rodney McKay: Well, you could put up a sign.
Maj. John Sheppard: Hi, folks. I hope I didn't crash-land on anybody.
Chosen answer: Because the ZPM allowing them to dial Atlantis was being used at the Antarctic defense outpost. They couldn't risk making Earth vulnerable to attack from Anubis by depleting it with repeated dialing to the Pegasus galaxy. Once they knew Atlantis was in serious danger, they had no choice.

ZPM from Antarctic was depleted in first dial, dial in Siege was done via ZPM from Egypt (SG-1: Moebius Part-1/2).
