It's the late 1800s in Puebla, New Spain, and for former Kid Hero turned teenager Leo San Juan, it was supposed to be another adventure. Preferably his last, as all he desires after a turbulent childhood full of supernatural derring-do is a normal life, his newly-invented sport of Leg Ball to catch on, and the attentions of the charmingly enigmatic new girl in the neighborhood....
- Badass Preacher: Friar Godofredo. As Quetzalcoatl's goons find out the hard way, the power of HIS FIST compels you! He's also a member of a secret society to boot.
- Establishing Character Moment: For the main cast.
- Leo is introduced as a teen whose special power to speak with and see spirits, combined with his childhood of heroics, has gained him a...reputation he's desperate to shirk - desperate enough to ignore warnings that an apocalyptic threat is rising.
- Teodora is introduced as a snarky ghost with a deathly sense of humor whose selfish and selfless sides are shown simultaneously when she interrupts Leo's class to tell him off for shirking his heroic duties and ignoring his friends.
- Alebrije is introduced by coming out of the shadows to ask his good buddy Leo to play checkers...and try and convince him that shirking his duties is a bad idea for both his town and his friendship with his teammates.
- The End of the World as We Know It: What Leo and company attempt to avert in the second half of the episode. They succeed, but the villain ends up taking the town and everyone but Leo and company with him into his prison dimension.
- Generic Doomsday Villain: Outside of Don Andres and Leo's exposition for why a normally-benevolent creator god is trying to end the world, Quetzalcoatl is initially introduced as this. He's yet another supernatural bad guy for Leo and friends to defeat, only this time the world is at stake.
- Hope Spot: The villain is sealed away, Leo finally has the respect of the townsfolk, and he shares a kiss with the one girl who likes him for who he is. Then the villain yanks all that away from him into his prison dimension, with Leo and friends barely escaping.
- I Just Want to Be Normal: The driving force of the first half of the episode. Leo keeps trying to fit in with people his age...only for his supernatural ones to keep ruining his attempts. This leads to his continual, willful ignorance of his friends' warnings of an imminent apocalypse, eventually culminating in him breaking up with them.
- Windmill Crusader: Leo has become infamous for his "special time" (read: speaking with spirits no-one but him can see) amongst the younger townsfolk.
