In SI Greg saw the writing on the wall after Gretchen was axed. He then flirted with Hatch to try and save his own skin. Promo's hinted that this flirting might save Greg. It didn't.

Now we have Dave seeing the writing on the wall after Butch was axed. He's flirting with Heidi to save his own skin. Promo's hint that this flirting might save Dave. It won't.

I posted under an I_AM_HE thread that I thought 1 of 3 assumptions after last weeks episode would had to be wrong. They are:

1) Dave is voted out next - (indicated by game logic)
2) Heidi & Dave get cozy - (indicated with video evidence)
3) Jenna & Heidi are on the same page - (indicated by confessionals)

I now believe assumption 2 is wrong. Heidi & Dave aren't getting cozy (which I think indicates some level of emotional involvement). Dave's just trying to save his skin. And Heidi's just stacking the jury.

Assumption 1 & 3 are probably still correct.
