Big Brother 15 aired its 32nd episode Sunday night, featuring the Head of Household competition and the nomination ceremony.

Houseguests: Andy Herren, GinaMarie Zimmerman, Judd Daugherty, McCrae Olson and Spencer Clawson.

The episode began in the aftermath of Amanda's eviction at Thursday's live show. McCrae was paranoid that one of Andy or Elissa voted to evict Amanda. They both tried to convince McCrae that they voted to evict Spencer and McCrae didn't know who to believe.

He said that he didn't trust Andy even though he nominated Elissa for eviction alongside GinaMarie. The decision wound up sending Elissa out the door. The remaining houseguests were ecstatic to be evicting her.

The houseguests then participated in the Head of Household competition. The competition involved the houseguests looking at a pixelated image to determine a former competition they participated in and then identify it by which houseguest won it. Andy and Judd were eliminated first and second, so it was down to GinaMarie and Spencer.

In the final round, Spencer wound up beating GinaMarie, giving him his first Head of Household win of the season. As Head of Household, Spencer gave out "gifts" to the other houseguests, which could either be rewards or punishments.

Spencer gave the gift of "Friendship" to GinaMarie and McCrae, which involved the duo being attached to each other by a rope for 24 hours. He gave Andy the gift of "Wealth," which gave Andy the chance to win $5,000. Finally, he gave Judd the gift of "Health," which involved Judd having to do exercises whenever the announcer told him to.

GinaMarie and McCrae made a promise to each other that they would try to take each other to the final 2. McCrae asked GinaMarie if she had a final four deal with the other houseguests. GinaMarie denied the allegation, even though it was true.

GinaMarie talked to Spencer semi-privately and revealed that McCrae tried to make a final 2 deal with her. They agreed that McCrae was definitely going to be nominated this week. Spencer told McCrae that he wanted GinaMarie out, which wasn't true. He explained to McCrae that he had to nominate him to protect their "alliance" from getting found out.

At the nomination ceremony, Spencer did as predicted and nominated GinaMarie and McCrae for eviction.

The next episode of Big Brother 15 will air Wednesday at 8 p.m. on CBS, featuring the Veto competition, Veto ceremony and a surprise eviction.
