To say that Jordan is nothing but scenery is no exaggeration. She has zero skill at the game, she tends to trust anybody who talks to her, and she has only survived by riding on top of Jeff.
Somehow, though, she is destined to make the final four, and could easily skate by to the final three. At that point, a Michelle victory in the final HOH comps could lead her into the final two as Michelle is smart enough to understand that the majority of the jury house are allies of Natalie and Kevin.
Can an imbecile win Big Brother? Doubtful, but she's going to outlast her ride (despite her pleas for the house to keep Jeff over her).
