I'm not sure what's going on so that they didn't bring Paulie in, but I think they should have. It is a group of 8 called the 8 Pack, it's the 4 returnees and 4 newbies.
I'm hoping that they stick it out together, but I'm not sure I trust Zakiyah, just my opinion.
They are:
Frank
Nicole
James
Davonne
Corey
Tiffany
Michelle
Zakiyah
Natalie, Bridgett, and Bronte have formed an all girl alliance with each of them being a "Spy Girl", it was just too funny.
I think Paul, Jozea, and Victor have formed an alliance they call the Revolution, which again is too funny since one of them is probably headed out the door.
As you can see from the above "alliances" Paulie is really not in with a group, maybe he can work that to his advantage and float between all of them.
