I think that since neither Lane, Hayden or Enzo has real enemies, I think that if Lane took Enzo, the votes would be based on who won the most comps and who played harder.
If Lane wins the final HoH, I think the jury would view him as most deserving.
Brit, Kathy, and Ragan all liked Brit as well and, assuming she would campaign for Lane, and no one else in the house would campaign for either of them, I think Lane wins. In this scenario, I dont think Brit has to campaign much if at all.
I think Lane would be close to beating Hayden if they were the final 2; although Britney would have to campaign really hard for Lane in that scenario...she would have to play up Hayden already having the prizes and all that.
Of course, I could be WAY off base!
