"We all need to stop for air now and then, or we'll burn out. That's the one thing you people don't know how to do."
— Maj. Gen. Hank Landry
Landry arranges some downtime for the team to bond at O'Neill's cabin in Minnesota, but Mitchell ends up left alone with the general as the others are tied up at the SGC. As Carter, Teal'c and Vala investigate a rash of savage animal attacks across several planets, Mitchell and Landry's vacation is cut short when a local hunter is killed in remarkably similar circumstances.
"Uninvited" provides examples of the following tropes:
- Alien Autopsy: Dr. Redden dissects one of the mutant creatures after it's brought back through the gate, revealing that it's infected with a radioactive parasite.
- Aliens in Cardiff: Man-eating mutants in Minnesota.
- Arbitrary Skepticism: Discussed by Mitchell and Landry regarding the sheriff's suspicions about the creature.Mitchell: This sheriff doesn't think we've got a Bigfoot on our hands, does he?Landry: He's a decent enough guy, he probably just watches too much television.Mitchell: On the other hand, we have seen real-live alien monsters.Landry: He doesn't know that.
- Back-to-Back Badasses: The hunting party comprised of SG-1, SG-3 and General Landry all stand back-to-back in a defensive formation as the creature is stalking them.
- Bring It Back Alive: To begin with, this is Vala's opinion of what they should do with the creature, as it'll be more valuable that way. Unsurprisingly, everybody ignores her.
- Character Catchphrase: Carter's Abandoned Catchphrase of "Holy Hannah!" from the early seasons makes a comeback when the creature first appears in full view during the team's hunt.
- Continuity Nod:
- Landry picks up on Mitchell's prior comment that he doesn't really feel like he's in charge of the team and reminds him that he's the one who was so hellbent on getting the band back together in the first place.
- Vala asks Carter if she's gotten over her fear of sitting in Landry's chair yet.
- Carter states that Agent Barrett is recovering from being brainwashed by Ba'al.
- It's mentioned that this isn't the first time Ancient technology has allowed creatures from alternate dimensions to bleed into ours.
- A Day in the Limelight: Landry has a much bigger role in this episode than most others.
- Death by Irony: The local sheriff is gruesomely killed by one of the beasts seconds after Landry assures him he has nothing to be concerned about.
- Diving Save: Teal'c tackles Vala out of the way of the explosion after killing the first creature with a grenade.
- Formerly Fat: While not exactly thin currently, Landry reveals that he was this as a child after taking offense to an insensitive remark made by Mitchell.Landry: [about Daniel] Still in England. Seems he's met some lord or earl with a private library of ancient reference material on Merlin and Morgan Le Fay. He's obviously quite excited.Mitchell: Yeah. Like a fat kid in a candy store.Landry: [suddenly serious] I was a big boy in my youth. Never did appreciate comments like that.Mitchell: Yes, sir. Sorry, sir.
- Gory Discretion Shot: Pretty much every time someone is mauled by one of the creatures.
- Healing Hands: Vala makes a comment about using the Goa'uld healing device on the members of SG-25 after they're attacked.
- Heroes Gone Fishing: Landry drags the team out for some bonding downtime at O'Neill's cabin, despite the fact there's still a war raging on.
- Hidden Depths: Landry off-duty is revealed to be something of a Cloudcuckoolander and an animal lover who takes his birdwatching very seriously.
- Ignored Expert: Landry doesn’t listen to Vala’s suggestion to lure the creature into an ambush instead pursuing a more risky strategy of heading into the woods in the dark in small groups to hunt down the monster.
- Immune to Bullets: The creatures are incredibly resistant to weapons fire and are not fazed by a single P90 on full auto. Fortunately Teal’c has a grenade handy for the off-world creature and the creatures on Earth attack after the search teams have regrouped and can combine fire.
- In Harm's Way: Mitchell claims that the only time he feels "relaxed" is when he's in the middle of the action fighting for his life, and that he gets antsy with nothing to do.
- Incredibly Lame Fun: Mitchell's reaction when Landry starts enthusing about getting to see the "Fulvous whistling duck".Mitchell: That's a good one, sir. You know what, the hat really sells it.[Landry just looks at him]Mitchell: Oh, you're serious. Well sir, as, uh... tempting as a duck that whistles sounds, I was thinking about going for a run.
- Know When to Fold 'Em: Played for laughs when Teal'c loses the team poker game to Carter at the end of the episode.Teal'c: A true warrior... knows when to fold them.
- LEGO Genetics: The parasite somehow "rewrites" the host DNA to turn them into huge mutant creatures that don't even remotely resemble the original species.
- Make Sure He's Dead: After Mitchell kills one of the creatures, Vala proceeds to unload another clip into it, just to be sure.Mitchell: What the hell are you doing?!Vala: Rule number two: never approach a creature assuming that it's dead.
- Nice Job Breaking It, Hero: Carter realizes that the sudden appearance of the parasites is the result of the SGC scientists eliminating a radioactive field given off by the Sodan cloaking devices to make them safer for humans to use — except it turns out that the purpose of the radioactivity was to repel the parasites.
- Nothing Is Scarier: We never fully see the mutated creature Teal’c and Vala encounter offworld. Only its POV and partial shots of its corpse.
- Odd Couple: Teal'c and Vala form one when they're paired up off-world.
- Reckless Gun Usage:
- Lampshaded when a hunter comes charging out of the forest rambling about a creature while swinging a shotgun around; Mitchell tells him to watch where he's pointing it and eventually confiscates the gun before letting the man continue.
- And again when Vala fires a volley of shots into the dead creature... from behind Mitchell, without warning, as he approaches to examine it. He is not amused.
- Landry and Mitchell go wandering around the woods during hunting season in camouflage and a brown leather jacket, respectively. Any seasoned hunter knows that you should wear something highly visible, like the common orange hat or vest, so that another hunter with an itchy trigger finger doesn't mistake you for an animal (or a mutant interdimensional monster). But then, neither of them have much experience in sport hunting. On the other hand, a seasoned hunter should also know to clearly identify your target and not just shoot randomly into the brush like the guys who were spooked by the invisible Trust agent.
- Shout-Out: The creature is essentially a quadrupedal, horn-less pinky demon.
- Side Effects Include...: After the side effects of the cloaking devices are discovered:Vala: The Sodan have been using these devices for hundreds of years. You'd think there'd at least be a label on the side in bold print that says, "Beware: may cause deadly extra-dimensional radioactive monster-causing creature to appear"... or at least "Danger" would have been nice.
- Smart People Play Chess: Landry engages Mitchell in a chess match while they're at the cabin, though the latter is self-admittedly terrible.
- Suggestive Collision: Played for laughs when Teal'c lands on top of Vala after tackling her out of the way of an explosion.Vala: Well, I'm flattered, but I don't think we have time for this.
- Trash Talk: While the team are playing poker:Carter: I'm not much of a gambler.Teal'c: That is obvious.
- Villain Decay: Discussed in-universe when Teal'c comments on the fact that a few years ago the presence of the Goa'uld on Earth would be considered a major catastrophe, whereas now it's a secondary concern at most.Teal'c: It is ironic that not so long ago the mere presence of the Goa'uld on Earth would have been cause for great concern.Carter: Seriously! Who'd ever think that we'd have bigger fish to fry... or that you'd use the word "ironic" in a sentence?
- What Happened to the Mouse?: The creature they encountered on the first planet and the two creatures on Earth were killed on-screen, but the fate of the creature on the second planet was never shown or mentioned. Although, since that planet was controlled by the Ori, it can probably be assumed that one of the Priors used their powers to kill it if it kept attacking the population.
