History Recap / TheOwlHouseS1E4TheIntruder

* LiteralMetaphor: On the Boiling Isles, magic comes from the heart... or rather, [[HumanOutsideAlienInside from a "bile gland" attached to the heart]] that serves as a power source of magical energy. Since Luz doesn't have one, this makes it a bit harder for her to learn magic.

* MagicAIsMagicA: Eda explains the basics of witch magic during her first lesson with Luz. Spells require some sort of power source (like a witch's bile sack) and are cast with a spell circle, with the power of the spell being proportional to the size of the circle. This is shown to hold true for Luz's magic as well, when she draws a massive light spell on the wall to incapacitate Eda's cursed form.

* LiteralMetaphor: On the Boiling Isles, magic comes from the heart... or rather, [[HumanOutsideAlienInside from a "bile gland" attached to the heart]] that serves as a font of magical energy. Since Luz doesn't have one, this makes it a bit harder for her to learn magic.

** A subtle one, but in the previous episode King makes a bet with Eda because he wants to be Luz's teacher. Throughout this episode, he's still trying to teach Luz demonology, with her eventually calling him a great teacher

* DoesThisRemindYouOfAnything: When Eda finally talks about her curse, it's handled like a mental condition, and her elixer is comparable to treatment for it. Appropriately enough, she concludes with a fitting [[AnAesop message]]:
-->'''Eda:''' No one likes having a curse, but if you take the right steps, it's manageable.

** During King's demon lesson, one of the beast on his display is a giraffe.

-->'''Luz:''' Aww, you guys are sensitive!//
-->'''King:''' Even demons have ''inner'' demons.//

* WhamShot: King finds out what the second half of the tag on Eda's Elixir says, "An elixir a day keeps the curse at bay."

* DoesThisRemindYouOfAnything: When Eda finally talks about her curse, it's handled strangely enough like a mental illness or condition, and her elixer is comparable to treatment for it. Appropriately enough, she concludes with a [[AnAesop message]] that speaks to anyone with a condition:

* {{Aesop}}:

* {{Foreshadowing}}: Half of the tag on the elixir bottle is missing. King finds the missing half stuck to Luz's foot when she [[LosingAShoeInTheStruggle lost a shoe running away from Monster!Eda.]]

* LosingAShoeInTheStruggle: Luz leaves behind her left shoe to run away from Monster!Eda (and the other half of the tag King found stuck under her bare foot). King retrieves her shoe for her shortly after.

* RedHerring: The Snaggleback. With how much it's brought up, it would be easy to assume that the intruder was a Snaggleback. Such a demon was RealAfterAll, but much less impressive than King thought, and the real "intruder" was actually Eda.

* ShoutOut: The demons in King's presentation include Buer from the ''Literature/ArsGoetia'' and a triangular, one-eyed creature that looks an awful lot like [[WesternAnimation/GravityFalls Bill Cipher]].

* LosingAShoeInTheStruggle: Luz leaves behind her left shoe to run away from Monster!Eda (and the other half of the tag King found stick under her bare foot). King retrieves her shoe for her shortly after.

* HostileWeather: Storms of boiling-hot rain are a common occurrence on the Boiling Isles. Eda says they get plagues rather than weather, and mentions phenomena like "gore-nados", "shale hail", and "painbows".

** One of the creatures on King's board is a giraffe.

* CutenessOverload: When King, after applying bandages to himself and Luz, declares them to now be "boo-boo buddies", she [[{{Squee}} squeals]], her eyes dilate, and she loses the ability to sit up and collapses onto the ground in the fetal position.
