Darleen Dreamer (hidden)/theories

Who is this Darleen?
I was studying the file with the tumbnails, and I noticed something; this Darleen's thumbnail was with her family (Darleen is in between Dirk and Bella), while the other Darleen's was really, really close to the end, along with the "real" Skip Broke, in between Michael Bachelor and that maid, Lucy Hanby(?) Something tells me Maxis is messing with our heads...
