Willow and Amity's relationship rewrite: I Was A Teenage Abomination
In Understanding Willow there is a reveal that Amity was forced by her parents to stop being friends with Willow and later influenced by her new friends to bully her. This contradicts a bit with Amity's first appearance in I was a Teenage Abomination where she bullies Willow; they are completely alone in the woods, she is doing it completely willingly and seems to enjoy it.
The actual reason behind this is probably because at the time of making this episode, the writers haven't came up with the idea of Amity and Willow being childhood friends yet.
The in universe explanation could be that over the years Amity convinced herself that Willow actually deserves to be bullied (sort as a self-defence mechanism?). Or she is trying to bully Willow out of the Abomination track. I actually wouldn't mind that seeing either of that explored and called out to an extent. But, sadly, after Wing It Like Witches the show completely forgot about developing and exploring their dynamic.
So for my angsty Amillow (platonic and not) needs I'm going to rewrite this mess!
Episode rewrite rant/ideas:
The first time we (and Luz) see Amity is in a group with Boscha and other mean girls. The girls make of Willow for having low talent in Abomination magic pretty much like Amity did in the og. They compare her to Amity - the top of the class. The whole scene Amity seems disinterested in the whole process of bullying, probably studying and/or practicing her magic (to distance herself from the situation), safe for the parts where she revels in praise. Maybe, when prompted by the other girls, throws in some half-hearted insults. The purpose of this scene is the same - introduce Amity, the fact she is a top student and takes great pride in that and the fact that Willow is bullied for being bad at magic. To the "first time viewer" (and Luz) this could still paint Amity as a cold Queen Bee who let's minions to the dirty work.
Some of the Amity's "insults" could in some way imply that Willow should change her track (partly because she is still scared that her parents might expell Willow). I imagine, Willow had an interest in plants even before getting her powers, so Amity would probably think that Plant track would be more suitable for Willow.
After the group leaves, Willow gets angry (the power of her anger is double explained by the fact that she was bullied and her ex best friend just stood there and watched, maybe even encouraged it in Willow's mind).
Maybe Willow had an idea of going to the Abomination course not only because of "better opportunities", but maybe it was originally an attempt to get close to Amity again or to prove that she is not powerless.
Willow: "Please, don't tell me you saw happened earlier-" Luz: "Actually i did! Who do they think they are to treat you like this?!" Willow: "*groans* Amity Blight and her friends - the best witches in the whole school." (Insert headcanon that the rest of the mean girl group are also best students of their respective tracks)
Maybe Luz even confuses Boscha for Amity, since Boscha seems like the meanest girl, yet Willow always focuses on Amity when she complains about the bullying. This would be a false clue that Amity is the main bully here even if she doesn't show it. In reality, her anger stems from their shared history.
I imagine, if Amity found out that Willow was actually good at magic, she would probably with a mix of hope that their friendship could be restored and frustration because all those years where she had to push away her only friend were actually for nothing.
But since Amity saw Willow's bad attempt at Abomination earlier this morning, she quickly turns suspicious. Since she had to work hard to become a top student, she hates cheaters and she hates the idea of Willow being a cheater.
When her top student badge gets snatched off from her, Amity's reaction is similar to the canon one. Her whole self-worth is tied that badge, plus, as we already established her friend group, this could threaten her authority in the group. I imagine she gets a tunnel vision from this point on - she is focused on the badge only, nothing else matters.
(More related to the Lumity stuff but) I don't think it a good idea to have Amity gleefully watching as Luz nearly gets dissected. Since she thought that "the abomination" was alive. It would be better if there was a more explicit hint that it's just her and Bump's plan to get a confession out of Willow or Luz.
I think that's all for this episode! Thank you for reading! :>
