For the second week in a row, a houseguest who thought he was evicted ended up back in the house -- and becoming HOH.

James, who was lied to by almost everyone and then evicted by a vote of 5-1, got voted back in on Wednesday when a majority of the houseguests went with "the devil you know" strategy when faced with bringing either him or a random previously evicted contestant chosen by viewers.

But they didn't count on an HOH challenge that was all about will and endurance. It came down to Natalie (who was willing to do whatever she could to keep Matt safe) and James (who was out for revenge), who stayed balanced on the disco-ball contraption pictured above for five hours. Natalie was starting to feel ill, and James promised her she and Matt would be safe, winning himself the competition.

The other dramas in the episode included Matt trying to pretend like he was one of the people who voted for James to come back in the house, which made Adam look suspect, and also made Adam mad. Also, Matt finally started to realize that he'd been treating Natalie awfully. We'll see how long his kind(ish) treatment of her actually lasts.

And the nominations? Ryan and Sheila.

Speaking of Sheila, I know the veto competition thing said she had to wear that unitard for a week, but it already seems like it's been years. Can she go back to regular clothes, please? Please??
