Hello Lis! I feel like getting enabled into doing things is the mark of a true roleplayer, tbh. I am here because of enabling. I have 2 Harry Potter characters at a panfandom game where we have zero business Pottering things up but like...it happened. Also Slug & Jiggers sounds like my kind of dive, tbh.
I think Percy and Persephone would be the two I'd imagine have had previous run-ins with my girls! Percy because, as you said, Ministry -- I imagine Mafalda is more polite than Elladora given department crossovers and such. As for Persephone, Elladora is actually low-key sleeping with Evan. Which means they have never met (unless they passed each other at the Ministry) and Elladora makes no effort to interact with Evan's kids. But I'm sure eventually they'll meet, because it'd be no fun otherwise!
