23. Jackie gets evicted during the first Double Eviction.
The season's first Double Eviction came as a surprise for all of the remaining Houseguests, especially because Shelli had already left the house earlier in the live episode.
As HoH, Steve, who had been a floater most of the game, pulled a fast one on The Goblins by choosing to evict Jackie based on information that the dancer was gunning for the engineering student. Later in the game, Steve would find out that info was false.
