  • Space 1999

    Space 1999 did episodes exactly like this one 25 years prior to SG-1.

    The team goes to another world and start to regress to a lower evolved form. It's up to Daniels allergies and a few dart guns filled with benadryl to save the day.
  • Shows how two seemingly differant types of people, bronze-age civilized people/prehistoric cavemen, really are the same at the heart. Both want to live out their lives to the fullest extent. Good episode. **Major Spoiler Alert** (basically total recap)moreless

    The episode starts in the briefing room, when SG-1 and SG-3 are going over their next mission. After they go over the mission, it shoots to the gate room, where Jack tells SG-3 to wait till a count of 10 then come through, so they have a chance to check out the area surrounding the Gate first. This turns out to be a bad decision because they get ambushed by the natives, and get beat on pretty good. But before any serious damage can be done to SG-1, SG-3 comes through the gate and saves them by scaring off the natives.

    They continue through the forest and find a girl being raped, and Sam insists that they stop him. When they are about to attack, they see figures dressed in white (clichéd I know) hurling rocks at the ‘cavemen’. After they scare away the ‘cavemen’, the people in white identify themselves as the untouched, and invite SG-1 to the ‘land of light’. They live in a palace that looks like it is straight out of ancient Minoan history. To them the ‘cavemen’ are called the ‘touched’. After realizing that there is nothing of military value to be gained from this planet, Jack makes the decision to return to Earth.

    When they get back to Earth is when everybody goes CRAZY! And I don’t mean “okay they’re a little weird”, I mean “go get the straight jacket these people are going into solitary confinement…NOW!”

    While briefing the General on the mission a Lt. On SG-3 goes wacko and attacks Teal’c (not a fair fight I know…for him that is) and is taken to the infirmary after being seen foaming at the mouth. Then a short while later, as Sam and Daniel are discussing the Lt., 2 other members of SG-3 go crazy, get into a fight, and throw themselves out the briefing room window.

    Then my second favorite part of this episode happens. SAM JUMPS JACK!!! Sounds to good to be true I know, and it happened in the locker room none-the-less! But he ended up taking her to the infirmary to be sedated.

    When Jacks meets up with Daniel in the control room, he tells him that Sam tried to seduce him. And when Daniel says that he is going to go check on her, Jack freaks out and goes all territorial, and he starts beating the living crap out of Daniel. But he is stopped by none other that Walter! All Hail Walter!!!

    Anyways back on track, Jack is put into isolation, and it is found out that Teal’c and Daniel are immune. So they are assigned the mission to go back to planet Star Wars (light side/dark side…duh) and to the light side to ask the people there for a blood sample so they can figure out how to stop the disease. But on the way there Daniel is taken by the touched and beaten up. The untouched end up refusing to have a blood sample taken from them, but Teal’c ends up taking one anyway, forcibly from one of the guards. We also get to see that Gen. Hammond was put into the same room as Jack except he’s wearing a straight jacket.

    After discovering that the disease is a histiminealilic, it feeds on histamine, the thing that blocks most people from having allergies, everyone gets the drug, recovers, and is assigned the rescue mission to get Daniel back.

    When they find Daniel, it turns out that his histamine wore off and he became one of the touched. Jack makes a comment about ‘having a girl on every planet’, and this statement sticks with him throughout the series. Although Jack doesn’t really have any room to talk. SG-1 gets him back to the palace and strike up a deal with the untouched for the histamine. You can then see the touched come out of the forest all better, and are reunited with their families.

    My favorite scene happens next when they are walking back to the gate, Sam apologizes to Jack for jumping him earlier. But he says he doesn’t even remember what happened, but then he asks her how her stomach wound is (she got stabbed by her roommate). She tells him that Janet says that it should heal fine, and probably won’t even leave a scar. Jack says he was worried, and when she sounds shocked, he says “Sure, because if you didn’t recover, then he would never see that sweet little tank-top number again!”

    This is my 4th all time favorite episode of Stargate SG-1, and is really good, considering it was only the 4th episode of the series.moreless
  • This episode is truly great as almost everyone turns into cave men

    “The Broca Divide” is definitely one of my favorite episodes of the season. O’Neill’s famous one-liners abound in plenty on this episode that make this episode really funny. The premise of a disease that turns humans into cave men is a really interesting storyline and this pulls it off perfectly. The funniest part of the episode is when Teal’C doesn’t know who Lucy is when O’Neill says “Lucy, I’m home!” The scene when Carter attacks Jack is another classic scene. If you plan to watch SG-1, this is an episode I highly recommend. It’s funny, serious and very interesting.

  • The first episode where we really see the quality that the stand-alone episodes are going to have.

    Apologies for any spelling issues in this review, I write in British English not American and I am mildly dyslexic!

    This is the first proper stand-alone episode that SG-1 did (I refuse to count the abysmal Emancipation) and has two main standout firsts: it marks the first appearance of one of the best-loved characters in the series, Dr Janet Frasier and it marks the first overt appearance of the attraction between Carter and O’Neill (and therefore must be a shippers delight!).

    The plague concept is an interesting one at this stage in the series and introduces the idea that it is not just the Goa’uld threat that our heroes will have to deal with in their explorations.

    One of the things I like about the Broca Divide is that it offers some nice character insights that are expanded on in future episodes. An example of this is Jack’s tendency towards self-sacrifice in order to help others. Another standard that this episode sets is the little touches of humour that make the series as a whole such a joy to watch, humour that is not just in the lines themselves, but also in the delivery.moreless
  • Good episode and Dr. Fraiser's first appearance

    This was a decent episode that had some good team bonding in it. While the story was a little weak there some good things like the mention of the broca divide which was interesting. There was also some good humor throughout like the Lucy quote. This episode was also the start of the Jack/Sam ship. This is also the introduction of one of the most beloved characters in the show Dr. Fraiser. This was a good Teal’c episode because with the team incapacitated he had to help solve the problem alone and he did a great job. In the end an OK episode that had many flaws.moreless

Trivia, Notes, Quotes and Allusions


  • TRIVIA (6)

    • You can clearly see the shadow of the camera as it pushes through the twin bulls head statues about 10 minutes in.

    • General Hammond says that the people SG-1 brought back from Chulak in "Children of the Gods (2)" identified the last four symbols that the Goa'uld used to escape. However, in that episode, the only one near the gate was Jack, and he didn't see the symbols either.

    • Teal'c incorrectly drew blood. He broke the seal on the vial and then inserted the needle. It should have been the other way around, yet he somehow managed to acquire a full vial.

    • The "C-2" label was missing on the door into the gate room in this episode.

    • When Teal'c and Daniel walked through the gate to get a blood sample you could still see their shadow even after they went through.

    • When dialing to P3X-797, they yet again used the Abydos coordinates.

  • QUOTES (10)

    • Jack: By the way, how is the wound?
      Sam: Wound?
      Jack: I understand you got stabbed in the stomach?
      Sam: Oh, yeah, it was nothing. With any luck it won't even be a scar.
      Jack: Good, I was concerned.
      Sam: You were?
      Jack: Sure, if it doesn't heal properly, you'll never wear that sweet little tanktop again.

    • Daniel: (about the people on the Dark Side) We came in contact with them. Isn't that special.
      Fraiser: So, the question is, why haven't you and Mr. Teal'c come down with the symptoms?
      Daniel: Ah, Mr. Teal'c...Teal'c's symbiote probably protects him.
      Teal'c: That would be likely.
      Fraiser: What about you, Dr. Jackson?
      Daniel: That beats me. You're the doctor, Doctor. Ah, maybe I have a natural immunity.
      Teal'c: Perhaps you will develop symptoms later.
      Daniel: Thank you for the moral support.

    • Jack: (about Sam) No, she uh, she tried to seduce me.
      Daniel: Oh, you poor man.

    • Teal'c: General, I would prefer to not hurt this man.

    • Jack: I'm a big fan of all this stuff, but art appreciation is not what this mission is about.

    • Sam: I was going to do my living room like this (Minoan reception hall) but it didn't go with my other stuff.

    • Daniel: (referring to night vision goggles) These don't look like my prescription.

    • Makepeace: You can count on us to watch your backside.
      Daniel: Actually, I was more worried about my frontside.

    • Jack: Lucy! I'm home!
      Teal'c: I am not Lucy
      Jack: I know that. It's a reference to an old TV... never mind. Open the door.
      Teal'c: I will summon the doctor.
      Jack: No, come on. I'm fine. I'm back to being myself. Just open up.
      Teal'c: I cannot be certain that you are back to being yourself. You referred to me as "Lucy."

    • Jack: Daniel, you dog! Keep this up and you'll have a girl on every planet.

  • NOTES (6)


    • The Letter Z
      Just before O'Neill enters the Stargate for the first time, he swipes a "Z" in the event horizon/puddle of water with his right index finger. In the books, televisions series and movies, the letter "Z", usually cut with his sword, is Zorro's calling card.

    • Broca's Area
      Area of the left hemisphere of the brain. It contains the motor speech area and controls movements of tongue, lips, and vocal cords. Loss of speech may follow haemorrhage into this area.

    • Jack: Lucy! I'm home!
      This line is a reference to the classic tv show I Love Lucy, where Ricky Ricardo always announced his arrival at home in the same way.

    • Sam: Pierre Paul Broca was a 19th century anthropologist.
      Pierre Paul Broca made important contributions to anatomy, physiology and anthropology, and he was the founder of modern brain surgery.
