"I'm beginning to realize that I'm not gonna solve this, and that one of your typically insane ideas is probably gonna be our best chance."
Dr. Rodney McKay, to Maj. Samantha Carter
Carter and McKay search for a way to shut down the gate as Anubis continues bombarding it with energy, with just hours left until it overloads and destroys all life on Earth. Meanwhile, Teal'c and Bra'tac are joined by Rya'c on a mission to locate Anubis's weapon and destroy it.
"Redemption, Part 2" provides examples of the following tropes:
- Ace Pilot: Rya'c has apparently inherited his father's skills in this area, outmaneuvering Anubis's forces in a stolen Death Glider in order to destroy the weapon.
- All Up to You: Teal'c and Bra'tac get captured by Anubis's Jaffa, leaving their rescue and the destruction of the weapon up to Rya'c.
- And Mission Control Rejoiced: When O'Neill returns safely to Earth after jettisoning the stargate into space at the end of the episode.
- Belligerent Sexual Tension: Played for Laughs; McKay thinks this is the dynamic he has with Carter, whereas she outright can't stand him to begin with... however, after they part on decent terms at the end of the episode, she says that she found him more attractive when she hated him (though going by her expression, she was most likely teasing him).
- Big Damn Heroes: Rya'c pulls off an impressive aerial rescue of Teal'c and Bra'tac.
- Blind Jump: When O'Neill suggests disposing of the gate using the unstable hyperdrive, it's noted that while they have no idea where it will end up, it doesn't really matter as long as it's not here. They then upload a patch so the hyperdrive will only go a few million miles away, a blip in galactic terms but more than enough to dump a gigantic bomb.
- Chekhov's Gun: The faulty hyperdrive on the X-302 is used to dispose of the stargate, once they've reprogrammed it to minimize the risk of the instability blowing everyone up.
- Coming of Age Story: Rya'c accompanies his father and teacher for his first real mission in the "field".
- Continuity Nod:
- One of the scientists suggests trying the same technique to shut the gate down that they used when it was connected to a black hole.
- Carter reminds O'Neill that Jonas gave up everything he had to bring them the naquadria.
- Upon seeing Anubis' weapon, Bra'tac doesn't recognize it as Goa'uld technology. By contrast, Teal'c instantly recognizes it as Ancient technology and remarks he's seen a similar construction before.
- Crazy Enough to Work: Carter's initial plan to have O'Neill tow the still-active stargate out into space. McKay also lampshades her propensity for these kinds of plans.
- Danger Deadpan: O'Neill employs this as he's rapidly falling back to Earth in the X-302 after the initial plan fails and his engines have burned out.O'Neill: I'll just... keep falling.
- Didn't Think This Through: When Chekhov relays Moscow's opportunistic 'Bargain with the SGC Using the Second Earth Gate' proposal, Hammond rightly points out the Russians are overlooking one very key problem.Hammond: Here's the part you obviously don't understand. Even if, and I stress "if" we are able to successfully dispose of this Gate, there's nothing to stop Anubis from starting all this over again with the second Gate. No one's going to be running a Stargate program, Colonel. The second Gate has to stay buried.
- EMP: McKay's first idea to shut the gate off involves firing an electromagnetic pulse through the wormhole. Not only does it not work, it makes the situation infinitely worse.
- "Eureka!" Moment:
- Carter has one when Jonas asks how they installed the stargate in a mountain through the small doors. She realizes that they can lift it back out through the top of the mountain, then they can fly it out into space so that Earth won't be in danger when it overloads.
- Another one when, after O'Neill is unable to get the stargate to a safe altitude with the X-302, he realizes that for these purposes the unstable hyperdrive is just as good as a fully functional one: it doesn't matter where the gate is sent, so long as it's not here.
- In the Back: Rya'c gets shot in the back with a staff weapon, though it doesn't really seem to bother him much.
- Large Ham: McKay has fun lampshading Anubis's penchant for theatrics.McKay: "Hey, Anubis, this is your agent. You're playing it way over the top, can you get serious please?"
- Major Injury Underreaction: Rya'c's only reaction to taking a staff blast is to say that it's "nothing he can't handle".
- Nice Job Breaking It, Hero: McKay's idea to shut off the gate using an EMP results in the computer systems temporarily going offline, Carter being electrocuted and cuts the remaining time until the gate explodes in half. To his credit, he does realize this, and becomes (slightly) more humble after the fact.
- Pet the Dog: McKay is genuinely concerned about Carter after she gets electrocuted and admits that not only does he respect her as a scientist, he's actually jealous of her ability to think outside the box.
- Race Against the Clock: Carter states at the beginning of the episode that the gate can only withstand the attack for another 54 hours. After the EMP fails, it gets cut down to 24 hours.
- Relocating the Explosion: When they realize they can't get the Stargate to deactivate before it is destroyed, the scientists attempt to come up with ideas to minimize the devastation. Quinn and Carter's solution is to simply throw the gate off the planet.
- Shout-Out: O'Neill points out that it doesn't matter where the hyperdrive sends him, so long as it's "a galaxy far, far away".
- Stupid Scientist: The two bickering scientists who are always seen together and seem to exist solely for Carter and McKay to put them down.
- Survivor Guilt: Jonas still has a bad case of this following the events of "Meridian", insisting that he should have been the one to make the sacrifice in Daniel's place.
- Tagalong Kid: Rya'c starts out this way after he insists on accompanying Teal'c and Bra'tac on their mission, though he proves his worth by the end of the episode.
- Technician Versus Performer: McKay explicitly identifies this as the difference in his and Carter's approaches to science, claiming that science is just as much of an art as music is, and Carter will always be better than him because she's a true artist while he just isn't wired to think that way.
- Teeth-Clenched Teamwork: Carter and McKay, at least to begin with. They do eventually come to something of an understanding, however.
- Throw the Dog a Bone: O'Neill asks whether Hammond can't throw the Russians a bone and give them their own team in exchange for use of the Russian gate — though he's mostly acting out of self-interest since he doesn't want a Russian officer on his team. His giving Jonas the empty spot on SG-1 probably counts too, given how he treats Jonas the rest of the time.
