Yeah, it had that line again. A callback to when it was mentioned in Bloodlines.
S2 Episode 2: In the Line of Duty
No closure with the SGC being shut down plot...not that it is hard to infer things went well for them after they sorta saved the world, but I suppose it was either that or action opening and the latter probably made for better tv or something...
And now it is Carter's turn to be a goa'uld host?
Things seem noticeably off, both in her mannerisms that the SGC start to notice, and in how she is acting compared to what the audience would expect a goa'uld to act. This is not a normal goa'uld.
And somehow Cassandra can sense goa'uld.
Sam gets captured and the team work on helping separate her from the symbiote.
Apparently there is also some kind of shapeshifter on the loose.
Hello Tok'ra. These are good guy goa'ulds. They are a slippery bunch, but we will see more of these people in future episodes.
The shapeshifting thing is apparently a goa'uld hired assassin out to kill Jolinar, the Tok'ra in Sam. Said Tok'ra might know where Sha're is. By the end of this series my apostrophe key will be worn out.
The assassin is pretty slick, able in infiltrate and kill Carter...but since SG-1 are all spliced with cats they have more lives than you can shake a staff weapon at.
Luckily the Tok'ra gave its life for Same to live etc etc and the baddie was zat'd to death.
Pretty much a by the numbers episode that also happens to introduce some threads for future exploration. a fairly average episode, especially after coming off of the season finale and season opening.
