"I know how infuriating humans can be. They have a hard time seeing past their own noses, don't they? But they can change if you help them to look deeper. And if they see the amount of good that you lot are capable of, then maybe... maybe they'll believe in you even when you doubt yourself."

Neron and Tabitha figured out how to get a congressional hearing to get against beast laws passed and they power Charlie to accept the character of a congressman. In the end, she conflicts with their desires during the conference and flips the table attempting to prevent the entry from securing any such enactment, something that prompts a hard and fast fight when Tabitha changes Charlie from the representative to an octopus. Presently, Neron communicates a message through all of Hell disclosing to them that he intends to carry the whole hidden world to the Earth's surface by utilizing dread — through the abuse of beasts — to open up the doors of damnation.

Discovering this out, the Legends choose to utilize Heyworld as a spot where they can put the beasts and make it a fun, adoring condition at such way, the overall population won't fear the beasts. During an initial occasion, Tabitha assaults the carnival with Zari's developed monster, giving Neron the dread he needs to open the doors of Hell.

In a last battle, Constantine and Neron fight with the previous obviously being stifled to death. It's at that point uncovered that Nate had advised Constantine to switch faces so that Neron is diverted. Utilizing a sneak assault, the genuine Constantine is then ready to slaughter Neron and close the entryways to Hell. With Neron out of the picture, Ray's ready to go to his body. Nate stays dead, but is in the end restored when the Legends, beasts, and aggregate of Heyworld assembles around to sing his father's main tune.

Towards the end, Zari shows up to help rejuvenate Nate back, thus evolving time. After her and Nate embrace, she changes into her sibling Behrad, caused by the change of the timeline.

Meanwhile, in Hell, after reluctantly helping John and Nora to get the soul of Ray Palmer in the form of coin, Astra Logue gives to the worker in Soul Exchange bank several soul coins of the worst villains, who intends to release them from the dead.


Preparation ran from December 20, 2018 until January 11, 2019, with a winter break from December 22, 2018 until January 4, 2019. Shooting ran from January 14 until January 24, 2019.[1]


  • The title references the name of the theme park that Hank wanted to create for Nate, but also doubled as a reference to the Legends introducing themselves to the world.
  • After Ava and Zari comment that they should have reached out to the real Trinity (Supergirl, Green Arrow, and the Flash), Sara says that she did ask, but they said no. Nate responds that they (the Legends) "should have done the crossover", a meta-reference to the fact that the Legends were not in the Elseworlds crossover with Supergirl, Green Arrow, and Flash, despite confirmation in "Legends of To-Meow-Meow" from Gideon and Ray that they were invited, but chose not to attend.
    • Their exact response according to Sara, "hard pass", is identical to what Nate said in "Legends of To-Meow-Meow" about being invited to the crossover.
    • Despite her being from a different Earth, and as far as has been chronicled has only been to Earth-1 to aid in crossover-related events (and a wedding), this episode reveals that Supergirl is actually known to its general public and popular enough to become an attraction at the theme park.
  • Astra takes a number of soul coins of history's worst villains from Neron's vault and releases the souls from hell, including Joseph Stalin - the leader of the Soviet Union; Caligula - who is known as one of the worst and most violent Roman emperors of all time; Mary Tudor - who burned hundreds of Protestants on the stake for not being Catholic; and Genghis Khan who took over most of Asia. There were also Lizzie Borden, John Wayne Gacy, Charles Manson, Grigori Rasputin, Benjamin Siegel, Kathy Meyers, Marie Antoinette, Damien Darhk, Henry VIII, Brutus, Black Caesar, Jack the Ripper, Clyde Barrow and Bonnie (Parker).
  • When the Legends are discussing finishing Heyworld to teach the public that magical creatures are nothing to be afraid of, Sara says "If we build it..." Ava then finishes Sara's sentence by saying "They will come". This is a famous quote from the 1989 film Field of Dreams.
  • Nora hitting Ray's chest is a parallel to similar scenes in "No Country for Old Dads" and "Tagumo Attacks!!!".
  • Behrad wears the same shirt under his jacket as worn by Zari in "Here I Go Again".
  • Constantine states that it will take more than a musical number to fix everything. This is a reference to "Séance and Sensibility", as well as an ironic foreshadowing of the Legends singing to bring Nate back from the dead.
    • Ironically, in The Flash episode "Duet", Barry Allen mentioned that his mother once said that "musicals have the power to make everything better", which is what ends up happening in this situation.
    • "Sweet Baby James", the song that Hank, the Legends and the people visiting Heyworld use to resurrect Nate, was also sung by Hank to soothe the Minotaur in "Tender is the Nate". Coincidentally, the same Minotaur plays accompaniment in this rendition.
      • The way that they start singing the song, with Hank's spirit being channeled through Mick to get everyone to join in, is similar to "Séance and Sensibility", in which Hank's spirit is also channeled through Mick, but for another reason.
        • When Mick first starts singing "Sweet Baby James" by having Hank's spirit channeled through him, the team notices Tabitha's staff glowing. Ray then says that if fear (which Neron tried to harness as energy to open a door to release all demons from Hell) could be energy, it makes sense that love can also be energy. This may be a reference to the Emotional Spectrum from the Green Lantern comics, where each color of the Emotional Spectrum represents a different emotion that can be harnessed through the use of a power ring to create light energy constructs.
          • In the comics, Ray Palmer was once a member of the Indigo Tribe, although this type of Lantern harnesses the indigo light of compassion.
      • Phil Klemmer has revealed that the singing in this scene was recorded live on-set, and Dominic Purcell (who portrays Mick) sang his line without rehearsal.[2]
  • As of this episode, it's possible that Nate's identity as Steel is no longer a secret; he continues to not use his helmet, and Sara calls him by name while gathering Heyworld's guests to sing.
  • When the Legends are trying to get Heyworld's visitors to join the singing, Gary says that they need everyone to hold hands. Nora then asks "Didn't they do this last year?" and Ava responds "We're part of the circle this time". This is a reference to the season 3 finale "The Good, The Bad and The Cuddly", in which the Legends (specifically Amaya, Mick, Nate, Sara, Wally and Zari) form a circle and hold hands to combine the powers of the Totems of Zambesi to conjure something to destroy Mallus.
  • This is the last episode to credit Ramona Young as a series regular as she is downgraded to special guest star in the next season.
  • This is the last episode of Legends of Tomorrow to centrally take place on Earth-1, as subsequent episodes happen post-Crisis, and are set on Earth-Prime.
  • The following story, "Meet the Legends", implies the Legends spent the rest of 2019 basking in their fame instead of continued time travel. If they were traveling in the temporal zone, Gideon likely would have detected the antimatter wall from the date of the Anti-Monitor Crisis.


  • Gideon mentions the Anti-Meta-human Act of 2029, but was previously mentioned in "Zari" that law came into effect in 2021.
    • However, it's possible that ripples due to time travel caused the law to come into effect later than it had in the previous timeline, or that two Acts of the same name, passed in different years, exist, as often occurs in the real world.
  • After Nate's death, Sara is shown hugging Ava in the background from a front view, but she is suddenly next to Zari when the camera moves above them.
  • In "The Eggplant, The Witch & The Wardrobe", killing Neron would have required both Constantine and Nora restraining him for several minutes with magic. However in this episode, Constantine is able to kill Neron single-handedly without struggle seconds after the latter leaves Ray's body.
    • This may be because of the difference in vessels, as well as Neron's severely weakened state after being forcefully rejected from Ray's body. This happened after the former mistakenly goes back on his word and kills Nate (which he thought was Constantine).
  • Ray and Zari can be heard singing at various points in "Sweet Baby James", though neither of their mouths is moving except in Zari's solo at the beginning of the song.
    • During the final chorus with the guests, Sara's lips are moving about a measure behind the audio.
