Timeline questions answered

Aquarium of the Dead Timeline Explained: Your Questions Answered

When does it happen, and why in that order? The questions people ask about the chronology of Aquarium of the Dead (2021): time jumps, flashbacks, cause and effect between scenes and the correct order of events, each answered with spoilers.

Q1

Why did the octopus reanimate and attack after the tagging procedure?

The octopus went into cardiac arrest during the tagging procedure, and when epinephrine was used to revive it, the drug triggered a unexpected reanimation. The creature then attacked Dr. Karen James and killed the two workers before escaping into the facility's ducts.

Foreshadowing: Earlier in the film, Miranda receives a transmission warning about disposing of epinephrine, which hints at the danger the drug poses.

  • octopus reanimation
  • epinephrine
  • zombie outbreak
  • aquarium
Q2

How did the other animals at the aquarium become zombies?

The reanimated octopus excreted contaminated slime that spread through the tank water and into the other enclosures. This slime infected the other animals, causing them to reanimate as zombies and shatter their tanks in a panic to escape.

  • contaminated slime
  • zombie animals
  • infection spread
  • outbreak
Q3

Why did Daniel lie about disposing of the epinephrine?

Daniel Hanley conspired with Senator Blackburn to cut costs at the aquarium. He claimed to have disposed of the epinephrine from Eden Wildlife Zoo, but he never actually did so. This negligence directly caused the octopus to be exposed to the drug and triggered the entire outbreak.

Foreshadowing: Daniel's assurance that the disposal was 'taken care of' before leaving for the VIP tour raises suspicion about his true priorities.

  • daniel hanley
  • betrayal
  • epinephrine
  • blackburn
  • conspiracy
Q4

How did Karen discover the zombie animals were blind?

Karen realized the reanimated animals were blind when she observed their behavior, they relied entirely on sound to navigate and hunt. She used this weakness to her advantage by playing music on her mobile phone to distract and steer the dangerous creatures away from the group.

  • blind animals
  • sound navigation
  • karen james
  • survival tip
Q5

What happened to Beth and how did she die?

Beth Mackenzie had a starfish latch onto her abdomen after it slipped into her notebook earlier in the film. The parasitic starfish attached to her and began feeding on her. Despite the group's frantic attempts to detach it, they were unable to save her, and she succumbed to the creature's feeding.

Foreshadowing: The scene where the starfish infiltrates Beth's notebook foreshadows its later attack.

  • beth mackenzie
  • starfish
  • parasite
  • death
Q6

Why did Clu sacrifice herself fighting the octopus?

Security chief Eddie 'Clu' Cluwirth made a valiant attempt to kill the reanimated octopus in the basement. Her attack failed, and she sacrificed herself in the process, allowing Miranda to continue working on resetting the power to lift the lockdown.

  • clu
  • octopus
  • sacrifice
  • security chief
Q7

How did Miranda and the others escape the aquarium?

Miranda Riley used a stray power cable to electrocute and kill the octopus, ending its threat. With the creature dead, she was able to reset the aquarium's power, which lifted the lockdown and allowed the surviving group to escape through the unlocked doors.

  • miranda riley
  • power reset
  • escape
  • octopus death
Q8

What happened to Skylar and why did he die?

Skylar, on a VIP tour with Daniel, was killed during the group's attempt to reset the power. When they encountered zombified walruses, Skylar's nerves snapped under pressure, and he was fatally attacked by one of the creatures.

  • skylar
  • walrus attack
  • death
  • vip visitor
Q9

What was the transmission Miranda received about?

Miranda received a cryptic transmission from Eden Wildlife Zoo warning her to dispose of any epinephrine the aquarium had received. This warning hinted at a larger risk behind the outbreak, but the message came too late to prevent the disaster.

  • transmission
  • eden wildlife zoo
  • epinephrine
  • warning
Q10

What was Blackburn's involvement in the outbreak?

Senator Bailey Blackburn was working with Daniel Hanley to secure more funding for the aquarium while simultaneously conspiring to cut costs. This cost-cutting scheme led Daniel to skip disposing of the epinephrine, which directly caused the zombie outbreak.

Foreshadowing: Blackburn's interest in securing funds for the aquarium seems altruistic at first but is later revealed to mask his role in the cost-cutting conspiracy.

  • sen blackburn
  • daniel
  • conspiracy
  • cost cutting
  • outbreak cause
