I don't think it's been discussed about what Will's plan is to prevent Ho-ho-ho Janie Bird brain from winning HOH.

Are you kidding me?
I think he's gonna throw it, Will goes final 2 no matter what, and he knows the kind of competitor Janelle is, she won't just give up to Chilltown.
She wants to win, she isn't going to let Boogie sit in her seat without a fight.

I'm sure if Boogie wins, Will is happy to sit next to him, but Will also knows it would make great TV to have himself and Janie in the final two.
Will thinks he wins either way, and maybe he does.

Boogie got played by Will as much as everyone else in the House.
Will has been working to cut Boog's side alliance ( Erika) out, while keeping his side alliance ( Janelle) with him.
Would he cut Boogie loose? We won't know because Will won't have to make that call, he'll let Janie and Boogie battle it out, and both would take him to the end.

And everyone who thought Janie was stupid for teaming up with Will? Looks like it took her to final 3, with a good chance at facing the jury.
I don't see James sitting there.
