You know, I was thinking the same thing. Jennie said it best, "It's not that hard to do."
If she is not a mole, I can't believe they don't just evict her, but it's probably more fun for Big Brother to punish the others as a result of her problems.
As for when the rest of the housemates go, I have heard a rumour about a mass eviction but have not seen it yet. I have also heard a rumour that the house next door may be coming back.
Now, with the finale coming up on month away, I wonder why they brought in fresh meat. I hated that twist, I really did.
