Easily Once Upon of Swap, it's filler, and not even good filler like Fly from Breaking Bad. The only scene in that episode I liked was hooty.
Some other issues with OUAS:
How does Eda not recognize her sister's face, voice, and mannerisms are different? With Boscha you can make the argument she doesn't pay attention to Luz enough to recognize her face at this early point in the show
Luz is an idiot in this episodes for drawing attention to a WANTED CRIMINAL
Despite the moral, no one learns a lesson
The episode ends with Eda and King not helping Luz, ruining the moral even more
I just hate Boscha
As far as ranking my least favorite episodes of Disney TVA's Big Three, I'd rank it above Mother of Olms but below Roadside Attraction
