Will they or won’t they? That’s the question before tonight’s big vote which could change the course of the game for the rest of the season.

Will Mallory and Melody stay true to the Mosh Pit alliance and target Kamu if they can?

Melody and Mallory spoke alone last night in the bedroom.

Mallory argued that the Most Pit alliance didn’t explicitly tell them what to do.

“I just don’t want to make an enemy out of Drew,” said Melody.

Mallory said if they vote out Kamu over Haley they will be seen to be working with the Icons for sure.

They see no reason to blindside Yash especially if they don’t have a reason for doing do.

“We should just vote for Haley to leave and play dumb,” said Mallory.

Mallory is also concerned about blindsiding Drew and Barrett.

“I don’t think we should. At the end of the day, we have an alliance with them,” Melody stressed.

Mallory suggested telling Drew and Barrett right before the vote what they are doing, voting Kamu out if he doesn’t come down.

“I know it is the right thing to do but it f—–g sucks,” said Melody.

Melody and Mallory met with Drew after talking things over some more.

“You guys want to keep him?” a stunned Drew said of Kamu.

“There are pros and cons,” said Mallory.

“There are pros and cons for everything,” answered an irritated Drew. “You guys are bulls—–g me. There is no way. No, we should not keep Kamu.”

Drew asked Melody if she was “for real”. “I am serious,” she said.

Mallory is worried about making LaLa, Yash and Taylor upset.

“I am winning HoH and I am putting all of their asses up,” said Drew. “You guys want to keep trust with them and break the trust with me?”.

Mallory and Melody pushed the notion that the Icons lie a lot. Melody says she doesn’t trust them.

“But, Barrett does,” said Drew.

This morning Devens talked to Dee and Drew as they were getting up. He vowed to blow up everyone’s game if the vote doesn’t go how it should tonight. Drew maintained that he is voting with them.

“I do think Haley is the one leaving today though,” said Drew.

“As I told you, personally it is fine but if the vote doesn’t go what we decided it will be the nuclear option for me. I will reveal every secret I have ever known,” said Devens telling Drew that goes for him too.

Yesterday, Devens revealed his plan if the vote doesn’t go as the Mosh Pit alliance discussed. He will politely invite everyone to a house meeting and blow up everyone’s game.

Kamu, Haley and Angela will have one last chance to save themselves in the BB Block Buster competition on tonight’s live eviction show.
