Instead of Tater, Nellie's the one who is in search of her "final foam", while Tater's the one enjoys messing with her when it comes to her dreams. As for the primos, they also changed personalities as well.
In the alternate universe, Instead of living in Hacienda Hills, the Ramirez family are living the highlife as residents of Fresedena.
In this universe, Tater's a orphan at the Fresedena orphanage, after being left there when she was just a baby. Years later, she was adopted by the Ramirez Humphrey family.
Tater was really shy at first, but after spending time with her big new family, she realizes that family doesn't have to be by blood.
Based on the infamous Loud House fanfic story "Requiem For a Loud" by UnderratedHero, Tater finds out she has a terminal illness, only having at least 3 weeks to live. The only ones who know so far are the adults in the family, and the older Primos (Lita, Cousin Bud, Nacho, Tabi, and LotLot), with their younger siblings none to wiser.
With how much time left, Tater wants to spend every waking moment with her family before her fate is sealed.
