Held captive by Hathor, Daniel and Carter can do nothing but watch as O'Neill is implanted with a Goa'uld symbiote. Meanwhile, Colonel Makepeace leads the rescue operation from earth after receiving information as to SG-1's whereabouts, and Teal'c attempts to rally support from the Jaffa on Chulak.
"Into the Fire" provides examples of the following tropes:
- Ace Pilot: Teal'c manages to "thread the needle", a notoriously difficult maneuver to pull off, on his first try without any prior training.
- Break Out the Museum Piece: Bra'tac and Teal'c dig out the "Needle Threader", a variant of death glider designed to be flown through the wormhole that was apparently discontinued after too many Jaffa crashed it into the gate.
- The Cavalry: Makepeace leads the rescue operation from the SGC after receiving intelligence as to the whereabouts of SG-1. And then Hammond, Teal'c and a handful of free Jaffa put together a force to rescue them when they get cut off.
- Complaining About Rescues They Don't Like: After Makepeace and his team are taken captive by Hathor's forces:O'Neill: Nice rescue, Makepeace! Good job!
- Cover Identity Anomaly: O'Neill's plan to impersonate a Goa'uld might have worked, if not for the fact that he only knows one word in their language. Still, it only had to work for a minute, so good enough.O'Neill: Jaffa! Kree!
Trotsky: [rapid stream of Goa'uld]
O'Neill: ...You heard me, I said "kree!"
Daniel: ...Jack?
O'Neill: Hi, guys. - Disney Villain Death: Hathor gets one when O'Neill throws her into a vat of liquid nitrogen.
- Forced to Watch: Daniel and Carter have to watch helplessly as O'Neill is implanted with a Goa'uld symbiote. Hathor also tells O'Neill that once the Goa'uld has taken over, he will be forced to watch from inside his own body as it uses him to kill the other two.
- Frontline General: Hammond's response to being told that the President will not authorize any further use of manpower on the rescue operation is to step through the stargate himself.
- Heroic BSoD: Daniel after watching O'Neill implanted with a Goa'uld. The same awful fate has now befallen his wife, brother-in-law and best friend, and this time he witnessed the horror up close.
- Imperial Stormtrooper Marksmanship Academy: The tower snipers.
- Also a rare one for the SG teams - during a brief firefight inside at ranges of perhaps 10-15 meters the sheer number of bullets they fire vs the very few that actually hit is actually quite staggering.
- In the Hood: Hammond wears a light colored robe and hood to blend in on Chulak when he listens to Teal'c's Rousing Speech described below. Hammond reveals himself to Teal'c after the speech is over and the ones who believe in Teal'c are still there.
- Kill It with Ice: How O'Neill dispenses with Hathor. Earlier, the Tok'ra spy is able to kill the symbiote inside O'Neill this way, by putting him back in the cryogenic chamber before it's managed to take control.
- The Mole: The female Tok'ra operative in Hathor's ranks, who was able to leak information about SG-1's whereabouts to Makepeace at the beginning of the episode and later intervened to stop the Goa'uld symbiote from taking possession of O'Neill.
- No One Gets Left Behind: Twice subverted by Makepeace, despite his enthusiastic volunteering for the rescue mission: first, when he finds out from Daniel and Carter that O'Neill has been taken as a host, he tells them to consider him a casualty and that they can't afford to go looking for him. Later on, there's a blink-and-you'll-miss-it moment in the Tok'ra tunnels where Daniel goes back to help a fallen Marine and Makepeace literally drags him away as they're still under heavy fire.
- Oh, Crap!: When the rescue operation plus Daniel and Carter realizes that they're cut off from the stargate by an energy barrier, and then when the cannons rise up from the ground.
- Only a Flesh Wound: After Daniel gets shot in the leg by a staff cannon:Makepeace: How's the leg? Can you walk?
Daniel: It's just a deep, bleeding gash, I'll be fine. - Pre-Mortem One-Liner: O'Neill gets one shortly before throwing Hathor into the deep freeze:Hathor: We will destroy you for this!
O'Neill: And we would just like you to go away! - Redshirt Army: Most of the forces that Makepeace brings through the gate with him.
- Rescue Reversal: Makepeace and his team set out to rescue SG-1 only to end up getting captured themselves, forcing O'Neill and Carter to do some quick thinking to prevent them from being executed.
- Rousing Speech: Teal'c delivers one to the people of Chulak, though it doesn't exactly go as he'd hoped.
- Some Kind of Force Field: Hathor's base is defended by a solid energy barrier powered by an enormous generator.
- They Don't Make Them Like They Used To:Teal'c: There is an old Jaffa saying, General: "They do not build them as they once did."
- Villain Ball: Hathor.
- She tells O'Neill that once the Goa'uld she implants in him takes over, he'll be Forced to Watch as it kills Carter and Daniel. Which, given that she abducted SG-1 in the first place because they have information she needs, seems a little wasteful and shortsighted. Was no other symbiote due to mature and need a host, ever?
- After O'Neill's failed attempt to kill the symbiote with his bare hands, Hathor orders him taken somewhere "he can be properly restrained!" for the implantation. She has half a dozen Jaffa who could probably just hold him as they do the implantation then and there, but no, let's take him somewhere he can be Strapped to an Operating Table next to the one thing that can kill the symbiote (although, in fairness, that was probably the Tok'Ra operative's idea).
- What Does This Button Do?: O'Neill finds where the generators for Hathor's shields are hidden ostensibly by pulling a lever at random.
- We Need a Distraction: Daniel, Makepeace and several other soldiers are held at gunpoint; Carter estimates that the rescue should arrive within minutes, so they just need to buy enough time before Trotsky starts shooting. Cue O'Neill striding out into the middle of the field, doing his best impersonation of a Goa'uld.
