Last night on Big Brother, Adam won the veto, and HOH Sheila put Natalie up as the replacement nominee. Sheila and Sharon were sure Natalie was going to be backdoored. But then Adam and Ryan (the only vote-casters) seemed to be having second thoughts.

On tonight's episode, that was borne out when the guys called a house meeting to lay all the stuff they'd been hearing on the table. They blindsided Natalie with the "meeting" while she was in the middle of dyeing her hair. She claimed her loyalties were with the men, and Sheila was shocked. But the guys were convinced -- and it looked pretty obvious that Sharon was toast and Natalie was sticking around.

The jury house footage was interesting -- James, upon his arrival, blamed his eviction on Chelsia's negative departure from the house. I doubt that's true, but Chelsia did not take it well. But once he said he didn't care about the money and was glad he met her, they were fine. Ah, showmance!

When the votes were cast on the live show, I was shocked: Ryan voted for Natalie and Adam voted for Sharon. I guess they decided it made the most sense to put it in Sheila's hands, which actually wasn't a bad plan. After the break, Sheila evicted Natalie, who looked betrayed and cried.

During the HOH competition, the final question was, "There is still a pre-existing relationship in the house." The answer was fact, but a helpful graphic came up on screen: "(the guinea pigs)." In a tie-breaker, Ryan won the HOH over Sharon. I'm sure the houseguests are going to be driving themselves crazy trying to figure out who that pre-existing relationship is.

Next week: final three and the final HOH competition. We're in the home stretch, folks!
