One sibling of a former houseguest is showing how similar they are while other houseguests are showing off their ugly sides. In other words, it was Tuesday in the Big Brother house.

Head of Household: Nicole Franzel

Nominees: Bridgette Dunning, Jozea Flores, and Paulie Calafiore

Other houseguests: Bronte D'Acquisto, Corey Brooks, Da'Vonne Rogers, Frank Eudy, James Huling, Michelle Meyer, Natalie Negrotti, Paul Abrahamian, Tiffany Rousso, Victor Arroyo and Zakiyah Everette

The Big Brother 18 live feeds were the thing to watch on Tuesday, with many highlights (and lowlights). First, on a game level, Tiffany showed that she really is Vanessa's sister after spending much of the day in a paranoid frenzy.

It all began with Tiffany offering the idea of telling the other side of the house about how eviction night will go down just shortly beforehand. She said she thought they could offer a deal to someone like Paul in the event that he wins HOH next. James was worried about Tiffany talking to the other side of the house, which got back to Tiffany. Tiffany then proceeded to stress out about James not trusting her. She later spoke with James and ultimately smoothed things over.

However, much of Tiffany's fellow 8-Pack alliance members talked privately about their concerns with her. Da'Vonne, Frank and Zakiyah had a discussion and agreed that the might not even need Tiffany after this week or that they could always replace her with someone else. As it stands now, Tiffany may have to do some major damage control in the coming days.

Meanwhile, there were a few too many personal comments from the other side of the house, with shades of Big Brother 15. Paul was fuming for much of the night about James and privately called him "little Korean man." Bronte later joined in and said she would send him "back to Hong Kong."

Then there was Jozea, who was confident that Da'Vonne was on his side because she does not want to go to the end "with Caucasian people."

While many of the new houseguests have been talking about the future opportunities and success after the show, it's looking more and more like many will be in for a rude awakening when they leave the house.

Big Brother 18 returns with a new episode on Wednesday at 8 p.m. ET/PT on CBS.
