"I'm Megan Jones, by the way. Pleased to meet you. Also a muggleborn, if you didn't pick up on that on your own. And if you can't figure it out from the accent, I'm Welsh. From Swansea, to be specific. I don't really have a favorite subject yet because I didn't get to Diagon Alley until two days ago because my family was too busy to make the trip from Swansea to London. I've always loved helping my mam in the garden, though, so maybe Herbology. Although if it's anything like normal gardening and we end up kneeling in the dirt, I'm going to be very glad we spent the extra bit of money to get the Evans Charm on all my skirts."
That grabbed Harry's attention. While he couldn't be certain, it hadn't sounded like Megan had included an apostrophe in that… making it the Evans Charm, not Evan's Charm. And what was the likelihood of another magical person sharing his muggleborn mother's maiden name? "The Evans Charm?"
Megan rose to her feet, as did Hermione. The two looked at each other before grinning and drawing their wands, each tapping the tip of hers against a seemingly featureless spot on the waistband of her skirt. "Real women wear trousers." Anne, Daphne, and Cherise let out indignant huffs at that even as Harry watched in fascination, the two girls' black uniform skirts morphing into slacks identical to the ones he was wearing. "The patriarchy is keeping me down." The trousers became skirts once more and the two girls retook their seats, ignoring the looks the other girls and even a few of the boys were giving them.
Personally, Harry found it all quite intriguing. He knew his mother was a genius with charms, from mentions by others even before coming to this universe, but he'd never even thought to ask what she'd done with the ten years of life she gained in this new world. He probably should have, he realized. Maybe there were other, more useful spells wandering around in that brilliant mind of hers that he could put to good use.
