Honestly I'd never spared much thought to either Marge or Rita, but you've done such a wonderful job of making them fully realized people that I cared about them immediately.
She looked like herself, before she'd decided to become Rita Skeeter, special correspondent on whatever the latest area of interest was.
“Well, I didn't miss you,” she said to her reflection.
This is great, how she deconstructs her own self-made identity. Totally my headcanon for her now.
I love what you've done with the opening of the wizarding world, drawing the cultural response to that in such deft and spot-on strokes. Marge is great, adding her "No Wizards" sign in addition to all the other barriers she's already got to keep her world comfortably where she wants it to be. In her mind, all she has to do is reject a thing, and it stays rejected, safely out of view!
