On Sunday night, the contestants will play their final HOH, and this time the winner gets to decide who they want to keep as one of the final two at a chance of winning $500,000. Considering two of the biggest floaters I have ever seen are left on the show, I almost want to guarantee Rachel Reilly will win it because she is the most competitive and has won the most challenges this season. However, Adam Poch and Porsche Briggs have actually won a few challenges in the last couple of weeks so I don't think this is going to be a cakewalk for any of the contestants.
