I'm not sure what Britney expected from Hayden or from Lane. Did she perhaps believe that one of them would ditch the other and take her instead? Just because? Surely not and if she did, they didn't. What Britney did was help Hayden win 500K and Lane, small change; in the scheme of things. She screwed herself over. I doubt that Britney or Janelle would wish to sit next to each other in a BB-14 final 2 scenario; truth be known. Janelle is worlds more focused and treacherous than Britney could or would ever wish to be.
