I imagine Boschlow to be just like Lumity: The bully/mean girl falls in love with the good girl.

So instead of Amity, it is Boscha who realizes that she has developed feelings for Willow.

If I read the ending correctly, Skara says, "You look like you saw a ghost!" --Which I think is funny because of how Boscha asked Amity if the ghost she supposedly found was cute, before, so Boscha seems to have a thing for ghosts and maybe Skara knows that, which is why she saw her blushing and said that (generally people get paler when they "look like they've seen a ghost").

Just a funny thought!
