I don't get putting up Alex either. As far as Alex is concerned she thinks she has a final 2 deal with Paul. Honestly, Jess should use the hex to try to bring Alex to their side. She could tell Alex, hey I can make it happen that you won't go home, Cody doesn't care if he leaves or not, but if you give us your allegiance, I will save you. Jess could rub in the fact Paul put Alex up, that he's not on Alex's side, really drive the point home. Alex would be a great addition to them as she competes, unlike Matt and Raven who are just dead weight for the other side. Cody and Jess need people, it looks like they may have Matt, Elena is so flip floppy, they need more loyal people on their side to get Paul out.
