Big Brother 15 aired its 31st episode Thursday night, featuring the live double eviction. 

Head of Household: GinaMarie Zimmerman

Nominees: Amanda Zuckerman & Spencer Clawson

Other houseguests: Andy Herren, Elissa Slater, Judd Daugherty and McCrae Olson.

The episode began in the aftermath of GinaMarie nominating Spencer for eviction alongside Amanda. GinaMarie reiterated to Amanda that she had to break up her and McCrae.

Amanda made a pitch to Elissa to try and get her vote. She told Elissa that she would definitely be the next target once Amanda's gone. Elissa came around to the idea and told Amanda that she would definitely vote for her to stay. Andy interrupted their conversation and Elissa told Andy about her plan.

Neither Elissa nor Amanda knew that Andy was actually planning to vote out Amanda as part of his new Exterminators alliance (GinaMarie, Judd and Spencer).

Next, the houseguests voted in the live eviction. Andy and Judd voted to evict Amanda while Elissa and McCrae voted to evict Spencer, meaning there was a tie. As Head of Household, GinaMarie was forced to break the tie. GinaMarie voted to evict Amanda. Before she left the house, Amanda told Andy that she thought she could trust him.

The houseguests participated in the Head of Household competition, which involved digging through dirt to find two bones. Elissa and Judd came close, but McCrae wound up winning the competition.

McCrae nominated Elissa and GinaMarie for eviction. The houseguests then played in the live Veto competition. The competition involved the houseguests navigating through a maze. Judd wound up winning the Power of Veto. He elected not to use the Veto on either of them.

Andy, Judd and Spencer voted to evict Elissa, eliminating her from the game. She decided to not hug anybody on her way out and left the house.

The next episode of Big Brother 15 will air Sunday at 8 p.m. on CBS, featuring the next Head of Household competition and the nomination ceremony.
