Big Brother alum Janelle Pierzina discusses how Rachel Reilly’s improved social game gives her an advantage in season 27, focusing on alliances, strategy, and interactions in the house.

Big Brother Season 27 Week 6 revealed Rachel Rilley as the new Head of Household. With that, she shocked everyone after teaming up with fellow housemate Keanu.

Week five of Big Brother saw Zach Cornell leave the house after Ava Pearl put him, Vince Panaro, and Keanu Soto on the block. Now, there is a new Head of Household and three new nominees on the block. This time, it feels like old-school Big Brother.

The former Big Brother alum has recently made her surprise comeback in Big Brother season 27. She is the winner of Big Brother season 13.
