I had a heck of a time figuring out what the relationship between these two were and didn’t get it sorted until after page forty-three, when I was getting into “you absolutely HAVE to figure this out now” territory. And now that I went to such effort to get it figured out, I’m a little surly I can’t just lay it on you, but there’s no appropriate narrative way to do this right now and possibly ever, in the main comic. So I’ll just pout over here and confirm any suspicions you might have that although Ruth says “aunt”, they aren’t sisters.
