So, I'm sure this has already been pointed out many times, but in the photo, Lynnette and her friends (L-R: Viv and Miranda) are seen in front of the Royce household. Obviously, DPC has indirectly confirmed that there's no blood connection between Jill's family and the MC's, but I think it's decently clear that their mothers ran with the same crew. Going off hair, I don't think it's too crazy of a theory to predict that Miranda (redhead) is the mother of Bianca who we just met in "Crossroads." As easy as it would be to say that Viv (dark hair) is Jill's mom, we know from the "True Colors" opening flashback that that woman's name is Amelia. Still, I wouldn't be surprised if Viv is tied to the Royces somehow.
