ADRIA FIRES BACK ON HER WAY OUT

Just before exiting the front door, Adria takes a stand, going off on her former housemates, naming names and claiming that as Jury members, she and Natalie will be voting as a bloc. Marvin can't handle it and reminds Adria that she wanted to be thought of as an individual, but speaks as a group.

In the aftermath, we see Marvin talking about Adria's "sanctimonious" and "pompous" ways. Adria walks to her interview with Julie and continues to say she is simply playing the game as best she can, being true to herself. In a move that may have ramifications for the future of the game, Adria declares she is for Cowboy, Karen and Drew. She also reveals that it may have been "the coach in her" that was pushing Karen and Drew, thinking she could draw something out of them, an inner fire that she knew was there, but that had not yet come to the surface.

HoH COMPETITION: CHEMICAL REACTION

Before the HouseGuests can digest what's gone down, they are on to the Head of Household Competition, Chemical Reaction. The remaining HouseGuests, save outgoing HoH Marvin, stand atop a set of stairs. Before them are two flasks and a beaker all filled with fluid. Julie ask a question, and then each HouseGuest chooses either a TRUE or FALSE flask to pour into the beaker. If the liquid in the beaker turns blue, they have answered correctly. If the beaker's liquid is clear, they are out of the game. The HouseGuests are asked a series of questions about previous Competitions and the circumstances surrounding them. Drew emerges victorious, winning HoH for the second time.

DOUBLE EVICTION WEEK

As usual, Julie asks Drew how it feels to be HoH. He says he's psyched for the week. Julie then informs him that it will really be only 48 hours as this is a double eviction week, and there will be a Nomination Ceremony taking place live TONIGHT on the 24/7 video feed at CBS.com

How will Drew deal with the pressure of having to nominate two HouseGuests so quickly? Who will put in the hard campaign to sway Drew's decision? Find out Saturday at 9PM ET/PT on a special hour of BIG BROTHER 5.
