Big Brother Wiki

Allison Elizabeth Nichols Carroll was a houseguest on Big Brother 9 (US).

A gossipy figure in the house, Allison was in the center of conflict for the majority of her time in the house. After being paired up with Ryan Quicksall as her soulmate, Allison soon discovered that he was dating Jen DiTurno, whom she strongly disliked. Although she promised to keep it a secret, Jen and Parker Somerville decided to expose the secret, in fear that Allison would expose it first. This led to a target being put on her back and ended with her nominated for eviction. Additionally, Allison and then friend Sheila Kennedy decided to create a lie that they were a lesbian couple outside the house which they then told to Chelsia Hart and Joshuah Welch. They continued the lie for 11 days before finally coming clean, to the anger of Chelsia and Joshuah. After Joshuah and Sharon Obermueller won Head of Household in week three, Joshuah made it known that he was targeting Allison for the week due to her lie about the lesbian couple, her gossipy nature, and her flipping her vote at the eleventh hour at the last vote. After failing to win the Power of Veto, Allison and Ryan were evicted in a 2-0 vote. However, it was soon announced that only one of them would be evicted and the house had to vote between the two. Nonetheless, Allison was evicted in a unanimous 6-0 vote, placing 10th.
