With the team still being held prisoner at the Tok'ra base, Carter suggests they offer her dying father the option of becoming a host. At the same time, the complex comes under attack from the Goa'uld, leading O'Neill to suspect that the Tok'ra have a spy in their ranks.
"The Tok'ra: Part 2" provides examples of the following tropes:
- Aborted Arc: Daniel suggests that Earth could provide willing hosts for the Tok'ra, since presumably there would be plenty of other terminally ill humans willing to take on a symbiote to save their lives. This never comes up again in later episodes.
- Actually Pretty Funny: When Jacob first meets Selmak/Saroosh, he observes the dying host doesn't look so good. Selmak snarkily responds that Jacob (who's also in ill health) is no vision of beauty himself. Martouf tries (and fails) to restrain a smile while Jacob cracks up.
- Body Surf: Once he realizes he's suspected of being the traitor, Cordesh(Anker) abandons his old host and jumps to a different body in the hopes of avoiding detection.
No word on what happened to the symbiote that was already in there. - Borrowed Catchphrase: Jacob uses his daughter's "holy Hannah!" a few times.
- Broken Masquerade: Carter and Hammond fill Jacob in on what 'Deep Space Radar Telemetry' really means.
- Convenient Terminal Illness: One of the reasons the team gets off on the wrong foot with the Tok'ra is that none of them are willing to become a host for Selmak; fortunately, Carter's father just happens to be dying of cancer, making it a much easier decision for him.
- Cool Old Lady: Selmak's old host. Selmak might also count, considering that all the other Tok'ra characters use female pronouns when talking about her.
- Cruel and Unusual Death: Cordesh's former host, Firnan getting pulled into the "vanishing tunnels".
- Driven to Suicide: Cordesh's host allows the tunnels to collapse on him out of guilt at being complicit in Cordesh's betrayal (Anker's infiltration).
- Deadpan Snarker: Selmak turns out to be just as much of one as Jacob.
- Double Agent: Cordesh is actually Anker, who took Cordesh's identity.
- Fantastic Racism: From the Tok'ra's point of view, SG-1's refusal to even consider becoming hosts looks like this. Garshaw questions how they can hope to have an alliance when the humans are so disgusted by the entire Tok'ra way of existence. In fairness, she has a point: while SG-1 have excellent reasons for being reflexively disgusted by the Tok'ra's nature, on the grounds that their only real exposure has been through the Goa'uld (who took Daniel's wife and brother-in-law as hosts), and Jolinar, who forcibly (out of desperation) hopped into Sam, then died, that very disgust is something of an impediment to working with the Tok'ra.
- Insufficiently Advanced Alien: The other reason why the Tok'ra are initially reluctant to ally with Earth, as we have nothing of technological value to offer.
- Internal Reveal: Jacob Carter finally learns of the Stargate Program and Sam's involvement.
- Kill and Replace: Though never revealed in the series, it was discovered in the RPG that Cordesh was actually killed prior to this episode and replaced by a Goa'uld named Ankre.
- The Mole: Cordesh. Well, actually, according to the RPG, it was revealed that Cordesh was killed and replaced by Anker.
- My God, You Are Serious!: Jacob's reaction to Sam and Hammond's revelation of the Stargate Program. He initially thinks it's just a cover story and they're lying to him...only to gradually realize they are completely serious.
- Orifice Evacuation/Orifice Invasion: Since the Tok'ra prefer to enter a host via the mouth to avoid scarring. Carter looks appropriately squicked upon watching Selmak leave the old host and enter her father.
- Talking to Themself: Selmak's host claims she is quite the conversationalist.Carter: Well, that's good, Dad. You can spend hours cracking yourself up.
- Unwitting Pawn:
- Vomit Discretion Shot: Jacob, due to a combination of chemo and gate travel.
- Willing Channeler: Jacob voluntarily becomes a host.
- With Due Respect: When O'Neill orders Carter to leave Jacob/Selmak in the tunnels after their "blending" due to the complex coming under attack:Carter: Due respect, sir, but no. I'm not leaving him.
