It's the first show of a new BIG BROTHER season, and this year's theme is Do Not Assume.

Michael decides to reveal to the Four Horsemen that Jennifer, a.k.a. Nakomis, is his half-sister.

The noose continues to tighten around Mike's neck as Scott wins the Power of the Veto in the "Flaringo" ring toss game.

Despite his best efforts to plant seeds of doubt about the power of the Scott and Jase alliance, a houseguest gets evicted.

Nomination day arrives, and Head of Household Marvin begins his deliberations.

In a riveting competition called "Snag the Veto", Jase emerges victorious over a hard-working Lori to grab the Power of Veto.

Jase's decision to use the Golden Power of Veto on Holly proves to be a good thing for Marvin and the rest of the Four Horsemen.

The winner of Big Brother 5 is selected.
