hi julia!!!! v excited to have you here!! louis seems super cute so far 🥺

my most obvious one is lorcan. his grandpa still lives in ottery st. catchpole near the burrow and the twins would've spent a lot of time around the weasley-potter clan growing up. if he had ever wanted some sort of summer apprenticeship (or whatever!) to learn more about animals, he could've worked alongside either luna & rolf or spent time with newt taking care of rescued animals. (i don't imagine his animal collection is as big as it was in his youth, but i'm sure he's still looking after smaller ones even though he's well over 100 years old by now.)

i'm also working on noel finnigan-thomas (noelnoel) who might also know him, even if he's older? (he's 24 and a '21 grad.) i imagine dean and seamus still keep in touch with harry and ron, and at some point noel & his dads have been included in some weasley-potter clan cookouts.

noel also loves animals a whole lot!! but more in the sense of "LOOK AT THIS COOL FROG I FOUND!!!!" than like... any real animal caretaking. he WILL pick up injured bugs or animals he finds and try to take care of them, which probably means taking them to louis.
