The Heads of Household in the Big Brother 18 house have shown some erratic gameplay over the past week, but what are their true intentions for getting to the end?

Heads of Household: Natalie Negrotti and Michelle Meyer

Nominees: Corey Brooks and Victor Arroyo

Other houseguests: James Huling, Nicole Franzel and Paul Abrahamian

When Natalie won HOH last Friday it was clear that she wanted Paul out of the house. She convinced Michelle, who became co-HOH, to go along with the plan, with Michelle saying she wanted Paul out anyway. Natalie and Michelle then felt guilty after Paul and Victor asked them why they were on the block, and agreed to a Corey backdoor plan.

After Paul won the Veto, he took himself down and Corey went up. But Natalie, Michelle and James ultimately came to the conclusion that Victor was too strong to not get out now.

It's been difficult to tell from the live feeds exactly what Natalie and Michelle are hoping for in the endgame as they try to win the $500,000. But their HOH blogs posted on CBS.com reveal that the pair wants to work with each other, alongside James, until the Final 3.

"My target list in order to get to Final 2 is Vic, Paul, Nicole, Corey, James, and then take Nat to Final 2," Michelle reveals in her blog. "I think I could get away with taking Corey to the Final 2, as well."

As for Natalie, she says in her blog that her "strategy moving forward in this game is to eliminate the biggest competition beasts in this house and will do so by working closely with James and Michelle.

"I have put my complete trust in James this season and now I'm starting to get really close with Michelle. I cannot believe I have made it to Final 7 and hope to continue to make big moves in this house. I want to make America proud of the moves I've been making because I've grown a huge love and respect for this game."

It may be comforting for some fans to know that Natalie isn't interested in going to the Final 4 with James, Corey and Nicole. This has been a worry among the fan community over the past few days, with James seemingly gung-ho to have an all-showmance Final 4.

Of course, neither Natalie nor Michelle knows that a juror is coming back into the game, which may interrupt their plans. The Jury Battle Back and HOH competition will take place tonight on CBS as well as the live feeds. That's right, it's time for another endurance competition.

Big Brother 18 returns with another new episode Thursday at 9 p.m. ET/PT on CBS.
