Goof: Just after the fight between Ronan and Kiryk, Kiryk picks up his Wraith stunner off the ground and places it in its holster. However, the next shot shows him walking towards Keller with it in his hand about to place it in the holster.
Ronan Dex was introduced in the season two episode "Runner". This episode is appropriately titled "Tracker" to reflect Ronan's switch from being the hunted to the hunter.
McKay compares the short nights on this planet to the city Whitehorse in Yukon, Canada. The city is so close to the Arctic circle, that during the summer months, the city would have very short nights.
Kiryk has acquired a teleportation device that does not seem to be created by the Ancients or the Wraith. It is possible that this race is still alive as Dr. Weir mentioned many advanced civilizations were hiding from the Wraith in "Ghost in the Machine."
Celise's village was attacked by Wraith because Kiryk spent a night there, similar to the situation Ronon Dex caused in at least one village during his time as a Runner. In the Season 3 episode "Sateda", he returned to the village and was turned over to the Wraith.
The planet was designated M33-985. The planet's sun has a very gradual descent angle, meaning the world has very short nights.
When Keller tries to remove the tracking device she mentions that it is different from Ronon's. This must mean that the Wraith must have learned from their mistake and made the device more complex to remove.
(Sheppard walks into the infirmary, followed by Ronon)
Sheppard: Well, how's our little patient?
Keller: Oh, much better. She's a heck of a fighter.
(Sheppard looks at Celise, gesturing at Rodney.)
Sheppard: Is he bothering you? Cause I can have him removed...forcibly.
Celise (hopefully): Really?
McKay: Yeah, he's kidding.
McKay: Okay... here's the thing, I've been thinking and ahhh... I need to know your intentions.
McKay: With Jennifer.
Ronon: I don't have any intentions.
McKay: Oh. Okay. (turns to leave and begins to smile) Good.
McKay: (stops smiling and turns around)
Ronon: What do you mean by intentions?
McKay: I mean are you interested in her in a... romantic... fashion.
McKay: Good. (turns again to leave with a slight smile)
McKay: (turns around showing irritation on face) What?
Ronon: Maybe I do... have... intentions.
Ronon: Do you have intentions?
McKay: Well, of course I do, that's why I was asking you.
McKay: What took you so long?
Ronon: Oh, you're welcome.
Ronon: It's going to be dark soon.
McKay: Actually, we have two hours, 43 minutes, and 17 seconds. This planet's sun currently has a very gradual angle of descent and a very short night. I always make it a point to download the planetary data on every address I dial, even goodwill missions. Yeah, things like atmospheric conditions. soil consistencies, available water supplies… what?
Ronon: Just wondering how long you'd make it out here without your little gadgets.
McKay: You know, I think you'd be surprised, you know. I may not be exactly what you'd call an outdoors person. But that doesn't mean I don't find the man vs. nature thing uninteresting. Hell, I joined a scouting organization when I was a child. Lodge 14 of the Fort McMurray Eager Beavers.
McKay: Yep, large rodent, big teeth. They use 'em to chop down trees and build dams. Very industrious. I was with them for a few months before they asked me to leave, but I got the manual, still have it… Scouting for Beavers. Valuable resource.
Ronon: What the hell were you doing?
McKay: At the moment, killing Wraith!
McKay: (to Ronon) I'm sorry, but I guarantee you at some point you're going to need my help. You'll see. There'll be some problem you can't solve, and then you'll turn to me. I'll figure it out in the nick of time. And you'll say "Good job" or just grunt or slap me on the back harder than necessary.
McKay: Look, How are we going to get up there?
Ronon: You said something about solving a problem.
McKay: Yeah, technological problems, not rock-climbing problems.
Ronon: Thought so.
McKay: Mind your step, sir.
Burly Woman: Sir?
McKay: Ma'am, sorry. You have a... (Gestures towards mouth and looking at Ronon) That is clearly a mustache.
