We don't know for sure either that the HII is played this week either. I believe Jeff says the idol comes into play but that doesn't mean it is actually used at TC. Obviously if anyone KNOWS Amanda has the HII the HII in this episode could come into play on discussing on possibly using it or pretending to use it, etc. Remember the HII came into play last week also, it just was not used.

That being said, if Alexis is the boot that everyone seems to be pointing at, Natalie either wins immunity or the votes are split somehow. Just because Erik "appears" to be next in line doesn't mean he is booted if he doesn't win immunity. For all we know Amanda and Cirie may decide that the "threesome" of Alexis/parvati and Nat need to be split up and they recruit Erik for that job. A tie vote could happen OR Parvati is told what is going on and she votes with C/A/E because she feels she has to :shrug and Alexis is the one who goes b/c Nat has immunity.

But we don't know for sure b/c we don't know who wins immunity or what kind of deals may be struck or if Amanda does or does not use the HII either.
