The Terror Within Timeline Explained: Your Questions Answered

When does it happen, and why in that order? The questions people ask about the chronology of The Terror Within (1989): time jumps, flashbacks, cause and effect between scenes and the correct order of events, each answered with spoilers.

Q1

How do gargoyles reproduce in the movie?

Gargoyles reproduce by raping women. This is revealed when the scientists examine Karen and learn she is pregnant. The group realizes the gargoyles have been abducting women to continue their species, which explains why the creatures are specifically targeting female survivors.

Foreshadowing: The earlier radio mention of a female survivor being found hints at the gargoyles' reproductive targeting.

  • gargoyle reproduction
  • Karen pregnancy
  • monster mating
  • creature reproduction
Q2

Why does the group debate aborting Karen's pregnancy?

The scientists debate abortion because they know the fetus is a gargoyle offspring, not a human baby. They explain that gargoyles have a very short gestation period, making the decision urgent. Karen is reluctant since the fetus could have been fathered by her late boyfriend, but the group fears the consequences of allowing a gargoyle to be born in their bunker.

  • abortion debate
  • Karen fetus
  • gargoyle baby
  • ethical dilemma
Q3

What happens when Karen gives birth?

Karen gives birth to a live gargoyle, which immediately escapes from the delivery room and wreaks havoc throughout the bunker. Hal designs a plan to kill the newborn, but the attempt fails and results in the deaths of Hal, Andre, and Neil. The creature proves too dangerous to contain.

Foreshadowing: The earlier discussion about the short gestation period and the group's fear of a gargoyle birth sets up this violent outcome.

  • Karen birth
  • gargoyle newborn
  • Hal death
  • bunker attack
Q4

  • self-abortion
  • gargoyle pregnancy
  • accidental death
Q5

How do the survivors discover the gargoyles' weakness?

Linda and David discover that gargoyles are vulnerable to high-pitched frequencies when a stray dog whistle disrupts a retreating creature. This accidental discovery gives them a viable method to fight back against the monsters that have been terrorizing the bunker.

  • dog whistle
  • high frequency
  • gargoyle weakness
  • sound weapon
Q5

Why does the gargoyle abduct Sue?

The gargoyle abducts Sue with the intent to reproduce, following the species' established method of reproduction. After wounding David and injuring his dog Butch, the creature takes Sue and impregnates her, adding another deadly threat to the group's already precarious situation.

Foreshadowing: This follows the same pattern seen with Karen's pregnancy earlier in the film.

  • Sue abduction
  • gargoyle reproduction
  • creature attack
  • kidnapping
Q6

What method do the survivors use to kill the gargoyle?

The survivors devise a plan to lure the gargoyle into the ventilation system using a dog whistle, then destroy it with the exhaust fan. They later also use remote-controlled explosives to trigger an implosion, annihilating any remaining gargoyles in the bunker before their final departure.

  • dog whistle
  • exhaust fan
  • explosion
  • sound weapon
  • gargoyle kill
Q7

How many survivors escape at the end?

David and Linda are the primary survivors who escape, along with the healed dog Butch. They re-establish radio contact with the Rocky Mountain Lab and carry high-frequency equipment as they venture outside. The final defense destroys the bunker in an implosion, eliminating the gargoyle infestation.

  • David survival
  • Linda survival
  • Butch
  • escape
  • final survivors
Q8

Do the survivors make contact with other labs?

Yes, David and Linda re-establish radio contact with the Rocky Mountain Lab, which was previously unreachable. This contact gives them hope and a potential destination as they prepare to leave the Mojave Lab bunker behind.

  • Rocky Mountain Lab
  • radio contact
  • rescue
  • other survivors
Q9

What happens to Michael and John during the survey mission?

Michael and John are killed during a gargoyle attack while surveying the Mojave wasteland. Their deaths occur off-screen but are heard through radio communications. David and Sue later discover their bodies while searching for survivors and find the pregnant Karen nearby.

  • Michael death
  • John death
  • survey mission
