Remember, there is no wifi in jail. So don't murder anyone. Lis here and I have just the two.
Elsie Griffiths (this girl) is one of the bakers at the grocery store and is a fairly mediocre kitchen witch (though excellent baker!) after she decided that her natural hedge magic is totally not for her after a disastrous hedge jump. She's a bit of a mess as her judgment is usually questionable, but her heart is in the right place. She's Jacen's daughter and the family has been there for two generations. (Her grandparents immigrated there.)
Kitty Phillips (mermaidsongs) is the Vocal/Drama teacher and like her trope (Ariel), Kitty yearns to be up where the people are. She finds New Haven stifling, but considering the town is everything she's ever known she's sort of stuck. She's sometimes closed off and comes off cold, but she is usually willing to lend a hand (wouldn't want to be guilted about it after the fact).
I'm not sure how well Amelia would know these two, unless one of the kids they foster would know them? Or just passing knowledge?
