Enzo, Lane and Matt celebrate in the storage room, and Hayden's looking forward to revenge, while Enzo DRs that he just hopes Matt sticks to the plan.
In one of the bedrooms, Rachel lies to Brendon that she's not upset with him, and that he did his best. Then she adds that she knows what's going on, but adds, "I can't talk about it." Oh, I HATE THAT! She's referring to being the target herself. He says they'll make it again, but she pushes him away and calls him "emotional and sensitive," whereupon he emotionally and sensitively flounces out of the room.
Time for Matt's second HoH room tour, at which Britney and Ragan take another turn at mocking the oblivious Rachel right in front of her. In this case, they do it by acting like girls in old Beatles newsreels. After a short time, people start sneaking down one by one. As Britney explains in the DR, it's a game called "Trapped," which is what it's called when you're the last person in the room with Rachel and Brendon. And Matt just lost this round. HoH has its downsides too.
Matt and his half-zipped hoodie with no shirt walks into the HoH room and finds the Pandora's Box door in there. He reads us the envelope explaining the Pandora's Box, which in this case involves the "Diamond Power of Veto." The Diamond Power if Veto, by the way, looks just like the Golden Power of Veto, except it has fake diamonds instead of fake gold plating. It's up to Matt to open it or not, and he thinks out loud, telling us the only reason not to do it is if he's required not to tell anyone why he's doing anything. But then he opens the door anyway.
