Hello, Dea! I'm Angel. Do you pronounce that as Dee, Dee-uh, or Day-uh? I'm just curious. :D
Hooray for Fleur! Millicent would know of her from Fourth Year, and probably know by now that she's married into the Weasley clan, but other than that, I'm not sure they would have crossed each other's paths with any sort of purpose. Mils speaks French rather well and is currently trying to convince Pandora to go to Paris for a day of shopping, so she and Fleur have the language (and a love of Paris?) in common, at least. But randoms can be good, if you'd like to go that route.
