Juliet Darnell

 was a houseguest on Big Brother 1.

Juliet was a big underdog in her season. She originally joined an all-girls alliance with Avery and Christine on Night One, with a side-alliance of herself, Christine, Justin and William. Juliet never made any waves in the house during the pre-jury phase of the game, however, Juliet's pre-jury experience ended on a sour note when her #1 ally, Christine, was evicted from the game right before jury. Juliet was nominated for eviction on Week 6, unaware that it was a backdoor plan against William. When Mark, Juliet's rival, veto'ed her off the block, she was shocked, and she made amends with him and his showmance partner, Cris. Juliet won the second Double Eviction HoH and PoV, and was responsible for evicting Jacob.

Juliet then laid low for the next few weeks, until the Final Seven, when she won the "HoH Recast" power, where at any given nomination ceremony up until the Final Five, Juliet could use it to dethrone the current HoH and become the new HoH. This led to multiple deals being made with Heads of Household, convincing her not to use her power. She used her power in the Final Six, dethroning Samantha as Head of Household, and was responsible for Robin's eviction. Juliet seemed to have had all the cards, but was evicted during the second part of the third Double Eviction, ending her game in 5th place.
