Episode cast overview:
Eric Schneider ...


SG-1 discover nine Goa'uld corpses in a sealed chamber, Teal'c identifies the crest as the nine Linvris, minor rivals of the system lords. While reading a tablet containing page one of some war plan, Daniel unknowingly gets infected by a parasite, which gives him visual and auditive delusions back on earth. An epidemic of migraine causes the general to keep all SG-teams in the base for examination. Daniel was already in a padded psych ward cell when during a visit from the colleagues he hears Ma'chello's voice say the parasite has left to enter its real target, a Goa'uld: Teal'c, for whose symbiont it is lethal. During examination of the page turner which released the designer organism, Jack, Dr. Fraiser and Sam get infected by several parasites, only Sam is found immune, even able to kill it by hosting it. The race is on to find how and hopefully use that mechanism to save the other three infected ones... Written by KGF Vissers

Did You Know?


When they first discover the 9 dead Goa'uld (at the start of the episode) you see Samantha Carter shining a flashlight across the character's back/neck to show the entry scar. Then as she is talking and noves towards the dead body's face, you can see the actor blink when the light is concentrated on his closed eyes. See more »


Daniel: Why are you so quick to jump to the conclusion that I'm crazy? I mean I'm dangerous, I'm out of control? It's 'cause I'm kinda acting that way, aren't I?

Delusion and Parasite
25 November 2015 | by (Rio de Janeiro, Brazil) – See all my reviews

The SG-1 finds a chamber with nine Goa'uld bodies inside and Teal'c identifies them as the rivals of the System Lords, Linvris. Daniel finds a device and while reading it, he is infected by an alien parasite. Back on the SGC, Daniel is delusional and Dr. Fraiser locks him in a cell while the SG-1 is kept in quarantine for observation. When Jack, Sam and Teal'c visit Daniel in the cell, his parasite leaves his body and infects Teal'c. Further, Daniel overhears Ma'chello's voice telling that the parasite was intended to kill Goa'uld. Will Daniel convince his friends that he is not mad?

"Legacy" is a good episode of SG-1 with well-written story and screenplay. The plot is also well resolved with the skilled Sam finding a means to save the SG-1 and Dr. Fraiser. My vote is seven.

Title (Brazil): "Stargate SG-1: Legacy"
