What's interesting is that she is wearing her hair the exact same way....hmmm? Definitely looks like it is Cydney behind Aubry. Michele could win the F4 IC, we see her and Tai are very close. We also hear Tai at one point say, "I am on bottom, you girls all together", or something like that. He would say that especially if he knows that he is vulnerable and the easy thing to do would be to vote him out. This could be the "hard decision" that Aubry has to make at F4.
Cydney and Michele voting for Tai, Aubry with a tough decision....will she stick with Tai and go for the tie, OR, will she vote Tai out, and go with the girls?
Or, it could indeed be F3 Immunity necklace? Michele will have to win at least one of them...
