This is just my theory so feel free to rip it to threads
So, Ivette has won Part 1? This could be good in Janey's books. Let's say, Ivette won HoH - you would automatically assume that Janey would be out on her ass. However, if Janey works her magic like she has been doing, she might be able to survive and win the $500k.
If she speaks to Ivette, she might convince her that against Maggie, Ivette has no chance of winning. Against Janelle, she has more chance as the "friendship" dominates the jury. With Maggie gone by Ivette's vote, the friendship will be mighty annoyed and so will vote for Jannelle to win (maybe?) for revenge against Ivette.
Ivette is determined for the money and she might see that against Maggie she has no chance, but a better chance against Janelle. Hopefully this delusionment might make Ivette forget that her friends will turns against her as for what she did to Maggie.
Here's hoping... and here's hoping people understand this theory
