|Season||Big Brother 12|
Paola Aviles is the so-called "lost HouseGuest" from Big Brother 12.
Aviles, a 30-year-old unemployed real estate agent, was chosen as part of the show's cast and placed in sequester along with the other prospective HouseGuests. While in the sequester, she decided to quit the show. She was not replaced with an alternate contestant, leaving the season to start with thirteen HouseGuests.
- Paola Aviles shares the same distinction with Mellisa McNulty from Survivor: Fiji; both quit before the season started, with no alternates to replace them, which resulted in the season starting with an odd number of contestants.
