After meeting her biological family, Sarah learned just how small the world is. Sarah's oldest sister's childhood friend (and still best friend) was her best friend (Hope)'s baby sitter growing up. So even if Sarah had stayed with her birth family, she would have found Hope.
Sarah had to move out of state for a little over a year. Still, she got back and Hope was there to greet her. Distance is tough, but not for bonded souls.
Sarah tells Hope of how she loves her and would love to spend the rest of their lives together. Being straight, Hope declined. Deep down, however, Sarah knew an intimate relationship really isn't what she wanted. Sarah already had what she wanted. Her confidante, her best friend, her soul sister.
