The Fifth Race
14 September 2015 | by claudio_carvalhoSee all my reviews

Jack, Sam, Daniel and Teal'c travel to a planet and when Jack trips on a circle, he activates a strange device that holds his head and he faints. Back on SGC, the SG-1 has a meeting with General Hammond and Jack has a strange behavior, using different words. Soon they all know that the device has downloaded an alien language into his brain. Meanwhile Sam, Teal'c and two other soldiers travel to a planet expecting to help Jack. However they discover that the planet has two suns and they will burn with the heat and they are unable to dial to return to Earth. But Jack sends a schematic drawing showing how to fix the apparatus and the group returns to the SGC. Dr. Fraiser finds that Jack is using 90% of his brain capacity. What might have happened to Jack?

"The Fifth Race" is another original episode of Stargate SG-1. Jack's behavior is funny and his encounter with the aliens that have built the Stargate is a great moment of this show. My vote is eight.
