Big Brother 15 aired its 35th episode Sunday night, featuring a recap of the season and the beginning of the final Head of Household competition.

Houseguests: Andy Herren, GinaMarie Zimmerman and Spencer Clawson

The episode began in the aftermath of McCrae Olson's eviction on Thursday night. Andy, GinaMarie and Spencer celebrated their success in being able to make the final three. The episode flashed back to the trio coming clean about their alliance to McCrae on Thursday afternoon.

McCrae went to the Diary Room and explained that he might not vote for Andy to win if he made the final 2, considering he stabbed him in the back.

With McCrae gone, the final three celebrated with a brunch. The trio reminisced on the season and their process of getting to the end. Spencer commented on his Moving Company alliance (Howard Overby, Jeremy McGuire, McCrae, Nick Uhas and Spencer), which was unsuccessful, considering three of them were evicted in the first five weeks.

GinaMarie brought up the multiple romances that blossomed in the house this season. Some of the couples included Aaryn Gries and David Girton, Candice Stewart and Howard and Kaitlin Barnaby and Jeremy. They commented on the longest-lasting romance of the season: Amanda Zuckerman and McCrae.

The episode flashed back to Amanda and McCrae's fake wedding from earlier in the season. The houseguests dressed up in bed sheets and held a mock wedding.

There was also a comedic montage of various houseguests crying in the Diary Room at various points in the season. Many of the houseguests talked about hating everyone else and not trusting anybody in the house.

The episode flashed back to the night before Amanda was evicted from the house. Amanda and GinaMarie engaged in a fight in which they hurled personal attacks at each other. After the fight, Amanda yelled at McCrae for not standing up for her.

The episode ended with Andy, GinaMarie and Spencer walking out into the backyard to participate in part 1 of the final Head of Household competition of the season. The competition involved the houseguests holding onto a bar while roller-skating on a rink. Whichever houseguest outlasted the others would win and move on to part 3 of the competition.

The final episode of Big Brother 15 will air Wednesday at 9:30 p.m. on CBS, featuring the results of part 1, 2 and 3 of the Head of Household competition, the final eviction and the crowning of the winner.
