||Bo is a bisexual succubus. A succubus must sustain herself by feeding from the life force of male and female Fae and humans, via oral intake or the energy created through sex. In the first two seasons she was involved in a romantic triangle involving Dyson (a heterosexual shapeshifter) and Lauren (a lesbian human), in which rivalry existed between the two over Bo. Neither Dyson nor Lauren wanted Bo to be with the other, but they tolerated it. As the series progressed, Bo tried to have a monogamous relationship with Lauren, but being unable to feed adequately put her in jeopardy and interfered with her intention, and she had to return to feeding from other beings, including Dyson when it was imperative. The relationship between Bo and Dyson became an unequivocal friendship, while Bo and Lauren remained in love with each other through ups and downs, and episodic distance. By the series end, they accept their messy and complicated relationship for the ultimate goal of being together as a couple.
