Disclaimer - I don't own Harry Potter or Worst Witch. This is my third story for Froday Eternal Amnesty written for prompt three of table A which is enemy, and the idea of writing a side story to my one-shot crossover where Regulus meets Maud and Mildred on the train popped into my head, but the story is from Ethel's point of view about how in this crossover universe Mildred and Maud end up being her enemy number one.

Black and White: Blackest Black

They were enemy number one in Ethel's book, although she'd initially thought them too much beneath her for them to end up in the number one spot.

Maud Spellybody, after all, was a Pureblood nobody; her family members always sorted into Hufflepuff and never amounted to anything worth noting in the same way a Weasley never amounted to anything. She still remembers her mother speaking with the wife of Uncle Abraxas with certain ladies of the Black family about how Molly Prewett was fool enough to marry into the Weasley family and that her husband, Arthur, had yet to amount to anything beyond having produced an heir with the spare very much on its way.

The other—well, she was a Mudblood, her name not even worth mentioning, though her crime against the sanctity of everything magical was bothering to show up at the Hogwarts Express despite not having received a letter, which meant in Ethel's mind that she was worse than a Mudblood, but mud itself. This non-magical being should have had her memories modified and sent away.

But no, both of them had to end up on her worst enemies list right at the very top where Ethel's older sister Esmerelda Hallow should be, being that she was as perfect as she was. And she'd thought mud was simply an eyesore until the sorting—because the sorting made everything quite clear, starting with Regulus Black, her fiance, as Esme knew since she first met him that they were the best match for each other and declared him hers already, which she felt everyone else there agreed with.

Because those girls had corrupted him, just as his older brother had been corrupted, into going into a house other than Slytherin, with her eyes going wide upon hearing the hat declare for him very loudly, "Ravenclaw!"

And thus, she had to be in that house, that same as Regulus, to make sure those girls didn't lead her astray. " Ravenclaw. I must be in Ravenclaw! "
