Cultural References

  • This episode portrayed the concept of a clone/twin of the protagonist turning on them in a battle to the death, the concept is also shown in series as Star Trek: The Original Series, Rick And Morty, Regular Show, Star Wars, and several others.
    • One of the references in the episode, "Three Buckets," is when Fern wanted to be the only Finn and take over his life. This is a reference to a Star Trek episode, The Enemy Within.

Episode Connections

  • Fern discovered his abilities to disguise as others in the previous episode, "Whispers."
  • Finn says he is very sensitive to being abandoned. This may be due to his past family history.
  • In a hologram, Princess Bubblegum mentions the events of "Reboot"/"Two Swords" where Finn lost his arm again and his fight with Susan.
  • Finn discovers a new ability in his arm similar to when he found out his "second arm" was made of the grass sword in "The Comet."

Storyline Analysis

  • Finn's prosthetic arm is actually more than meets the eye. It can be used as several power tools and even a weapon, and has a microphone and holoscreen.
    • This explains why Princess Bubblegum spent so much time making it (since Finn first lost his arm in "Escape from the Citadel") compared to quickly making a new arm for Shoko.
  • With the "weed-whacker" mode on his arm, Finn kills Fern by accidentally cutting him in the chest and bursting him into pieces of grass.
    • However at the end of the episode Fern's remains are seen and his eyeball moves. This may imply that in some way Fern is alive.
  • The room in which Fern trapped Finn is very similar to the inside of the Finn Sword: it's an empty space with just a small amount of food and a chair.

Production Notes

  • This episode is the season 8 finale. [4]
  • This episode was released early on the Cartoon Network app on July 14, 2017.


  • The list of abilities of Finn's arm changes order twice. Once after Finn says "Huh." and then when the view zooms into the Weed Whacker option.
