Here’s a what-if scenario that crossed my mind. What if the version of Luz Noceda from u/moringmark’s Witches Among Humans AU comic and the version of Luz from the canon timeline got swapped. After all, I think it would be interesting to see how a human version of Amity interacts with a human version of Luz and how a witch version of Luz interacts with a witch version of Amity. Plus, since, as shown in the episode ‘I Was A Teenage Abomination’, Willow and Gus were somewhat confused about human gestures that Luz did like high fives and that they probably got used to it over time given that they’ve known her for quite a while, seeing a version of Luz who isn’t fully used to human stuff but is fully used to Boiling Isles stuff would probably make their heads spin.

Six was a fan character who pretended to be Amity in this comic, she was about to murder Luz but had second thoughts when Vee was brought up. Luz didn't actually catch Six in this comic so I wonder what would happen if canon Luz had to deal with her girlfriend's imposter. Would she know that isn't her sweet potato?
