Just an assumption at this point, but a possible spoiler in that Hayden will be the contestant who is out to sabotage the rest of the house guests. This is an educated guess based on the fact that, under the house guests biographies on cbs.com, Hayden is the only houseguest who was not asked what his strategy to winning the game was. Just a guess but I believe it will prove correct.
