Lessee. She overlapped with Bethanie at school for... some time. (I want to say four years but then I checked other things afterwards and the number fell out of my head.) Bethanie also likes books & tea, but not Quidditch very much unless it's at the national level (and even then, she doesn't remember players names) so they might get on.
Ron & Andrew might both know OF her but don't know her personally.
I've also been convinced to app a Spinnet sibling who will be in her year and house! And who knows about quidditch because her siblings are quidditch mad but doesn't actually enjoy it.
