Stargate SG1 - One False Step

This week on One False Step: IT'S TEAL'C'S FIRST INDEED!! They're just so cute! What happened to Dr. Fraiser in this episode? She seems very out of character. How exactly does daytime/daylight work on this planet? Mom and Dad keep fighting. Why hasn't the SGC made or bought some sort of buggy for long-distance travel? Also, Sam talks to her plants, okay?
