Abbey

Abbey placed 13th on Posey's Big Brother Season 1: Coral Reef after choosing to walk due to personal issues. Many houseguests and viewers speculate that she decided to self-evict due to problems with one of the production members whom she was having relationship problems with at the time.

Abbey's choice to walk after the HOH competition had no impact on gameplay as she left before nominations were made. Abbey had won a have-not pass, during the first HOH competition, which would have been used as a Sharkbait pass, as have-nots were never actually used in the game for unspecified reasons.

Summary
Abbey entered the house and played hard from the get go and attempted to build many social bridges from the very beginning. She received a have-not pass, during the first HOH competition, which would have been used as a  Sharkbait  pass. However, citing personal reasons, Abbey chose to leave the game on Day 1 right after the first competition, becoming the first houseguest in PBB history to do so.

Trivia

 * Abbey is the first houseguest to walk from PBB, walking on Day 1 and he only one to walk during the season.
