Sharon Obermueller

 was a House Guest on Big Brother 9. Sharon was the first female House Guest to return to the game after being previously evicted since Amy Crews. However, Sharon is the only House Guest to return to the game for reasons that weren't due to a twist. Sharon's first "soulmate" was Jacob Heald, and her second "soulmate" was Joshuah Welch after replacing Welch's former partner Neil Garcia after he quit the game. Sharon placed 4th, becoming the sixth member of the Jury.
