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 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 is like Mellisa McNulty from Survivor; they both quit before the season started.
