On the Big Brother live feeds, two houseguests exchanged valuable items to prove their loyalty to each other.

Head of Household: GinaMarie Zimmerman

Nominees: Amanda Zuckerman & Spencer Clawson

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

After a truly unexpected move that involved Elissa swearing her allegiance to her season-long enemy Amanda, the two women made another bold move. Elissa swore to Amanda that she would not vote to evict her on Thursday and decided to prove her loyalty by giving Amanda her wedding ring.

Amanda accepted Elissa's wedding ring and Amanda gave Elissa a pair of gold earrings, promising that she wouldn't go after Elissa if she stayed. Amanda realized that she had the votes to stay, assuming Andy, Elissa and McCrae would not vote her out.

Little did Amanda know that Andy had made another alliance. Andy told his Exterminators alliance (GinaMarie, Judd and Spencer) that he would definitely be voting Amanda out this week, but wanted to keep up with the charade that he was still aligned with Amanda. Andy found out about Amanda and Elissa's jewelry exchange and became furious at Elissa.

Amanda told Andy to give her one of his favorite shirts to prove that he would vote for her to stay. Andy promptly did so but told his Exterminators alliance that he didn't care about parting ways with the shirt. The Exterminators agreed to target Elissa after Amanda's eviction.

Since the vote will be 2-2 on Thursday, Andy said that he would try to pin the extra vote for Amanda on Elissa. The houseguests are assuming that there will be a double eviction on Thursday, so many of them are planning ahead. Elissa and McCrae agreed to target GinaMarie and Judd if either of them won HOH, but they've also expressed concern about Andy.

The next episode of Big Brother 15 airs Wednesday at 8 p.m. featuring the Power of Veto competition and the Veto ceremony.
