Each week, Big Brother host Julie Chen Moonves will weigh in on the latest events inside the house. This week, she reacts to being abducted by the Mastermind, Rachel Reilly’s return as the mystery houseguest, playing for the first Head of Household win, and the Secret Accomplice twist.

While Moonves’ disappearance was short-lived, the introduction of The Mastermind, an ominous figure in a creepy red mask, teased some of the numerous secrets of the house, including the HoH relic at the heart of the night’s second competition.

Julie Chen Moonves is proud of all the relationships that have blossomed on Big Brother. Speaking exclusively with PEOPLE in honor of the show's 25th anniversary, Chen Moonves, who has hosted Big Brother since it premiered on July 5, 2000, bragged about the show's track record for successful romances.
