Episode Quotes
Sheppard: How's it going, boys?
Rodney: Well, we'd be making a lot more progress if Timmy Torture wasn't trying to kill me every two seconds.
Zelenka: I'm not trying to... kill him.

Rodney: Let’s jack it up, see how far we can penetrate.
John: Penetrate?
Rodney: What?

Rodney: Sheppard, we’re coming in too steep, we need to ease up on the angle of re-entry.
Lee: In fact, you mean “entry.” You see, we never actually left…
Sam: Bill…
Lee: Oh right, right.

Dr. Bill Lee: Space is quite vast.
Ellis: You don't say.

Episode Goofs
The backpack Dr Lee is wearing when he's beamed aboard the Apollo is not the same as the one he was wearing when he stepped through the Stargate moments earlier.
