i think it also highlights their own preference when it comes to men in a way. hilda wants love and something sweet hence why she loves cee while zelda seems to prefer power and a more lusty and steamy affair (at least from what we saw so far bc i think deep down she does want someone to connect with a bit more than just physically)
honestly such a good point to make. as it examines the aunts, i think you;ve perfectly summed it up!
& not only that but harvey has a lot of traits that hilda reflects; good-heartedness, gentle, too stubborn about their comfort zones, and ultimately someone who looks to support. zelda and nick are both a little more mercurial, who understands the pull toward power and prestige, and whose allegiances are a little more self-sustained, tho its not a question of whether either loves sabrina.
