As much as I dislike Vanessa as a player, her as HoH this week puts her in a really interesting spot.
If I'm Vanessa, here are my two main considerations:
1) What can I do to not break up Austwins this week?
If she were to put up 2 of the 3, not only is she the #1 target of remaining two going forward, but she most likely loses 3 jury votes from them if she were to make it to final 2. As a numbers person, Vanessa knows if she can remain neutral with them until "she has no other choice but to put them up" later on in the game, I think Austwins will be much more understanding and would have no issues giving her their vote if she makes final 2. She's remained mostly cordial with them the entire game - no reason to ruin that right now.
I'd put up James and Meg. Assuming neither win veto, James most likely voted out.
2) What's the plan next week?
Best case scenario: John or Steve wins HoH and puts up Austwins. Even if one of them wins veto, the remaining 3rd Austwins member is put up and one goes home.
Not best case scenario but most likely okay: Austwins win HoH. Really think Vanessa would be okay in this situation since she's "choosing not to go after them this week." They'd feel like they're backstabbing her.
3) Who do I ultimately want to bring to final 2?
If I bring John, I lose. He's overall not disliked disliked by the jury and I think they respect his game. I think he'd get the votes over Vanessa. However, if I can somehow bring Steve, aka the snake and the pawn who has done all of my dirty work, the jury will most likely would not vote for him.
Bringing an Austwin would be interesting. If the jury were rational, they'd see Austwins had a HUGE advantage with Julia coming in and the Austin/Liz showmance. They basically hit the BB lottery. And let's be real - Julia especially did not do much to deserve the money. At least Liz has won competitions.
