Bianca

Their is a theory that Bianca is Miranda's, MCs moms bestfriend, which I 100% beleive. except the only thing that throws me off on this is Biancas age. while not confirmed, she seems to be a couple years older than jill which is a couple years older than MC. If she is than Bianca would have been a live during the flashbacks MC reads in his moms diary.

Im curious what eveyone else thinks about this. and/or clear this up, maybe ive missed something.
