Previously Evicted Contestant

Previously Evicted House Guest is a recurring twist in Big Brother. The twist gives players who were previously evicted a shot at re-entering the game and potentially winning. So far, 4 seasons have featured this twist (Big Brother 3, Big Brother 6, Big Brother 9, and Big Brother 13.

Big Brother 3
In Big Brother 3, the first four evicted House Guests were asked questions about how much they'd be willing to give up to re-enter the house. These questions left only Amy Crews and Eric Ouellette remaining. The remaining seven House Guests then voted for one of the two to re-enter the game, with Amy winning with a 5-2 vote.

Big Brother 6
In Big Brother 6, the House Guests learned that one of three House Guests (Kaysar Ridha, Michael Donnellan, and Eric "Cappie" Littman) would return to the game. Ashlea Evans was not eligible due to leaving sequesting. On the night the returning player would join the house, Kaysar won the right to re-join the house after receiving 82% of the public vote.

Big Brother 9
Big Brother 9 featured two previously evicted House Guests returning to the game for the first time in Big Brother history, although one of these was not due to a twist. Sharon Obermueller returned to the game to be the "soulmate" of Joshuah Welch after Neil Garcia, Joshuah's original "soulmate", walked from the game.

Later on in the game, similiar to Big Brother 3, the remaining eight House Guests had a choice of voting back in a "Mystery House Guest" based on a public vote (Alex Coladonato) or the previously evicted House Guest, James Zinkand. James won the right to re-enter the game after being voted back in by a 5-3 vote.

Big Brother 13
Big Brother 13 had a public vote to see which of the first four evicted House Guests (Keith Henderson, Cassi Colvin, Dominic Briones, and Brendon Villegas) would return to battle with the fifth person evicted for a chance to re-enter the game. Brendon Villegas won the public vote, beating Lawon Exum in the battle and returning to the game.

In-Game Success
Although a Previously Evicted House Guest has not won or reached the Final Two in the four seasons to feature this twist, three of them (Big Brother 3, Big Brother 9, and Big Brother 13) saw the previously evicted House Guest reach the Jury Stage. These players include Amy Crews (Big Brother 3), Sharon Obermueller (Big Brother 9), James Zinkand (Big Brother 9), and Brendon Villegas (Big Brother 13).
