Bo's relationship with Rainer didn't go over very well with her friends. She was left isolated from them while she worked out the truth about what happened to her.

In Lost Girl Season 4 Episode 10, Bo recovers her lost memories from her time on the train. The answers about who brought her to the train in the first place and how she became aligned with the Dark Fae are both huge shocks to her.

While Bo handles a threat with Rainer, Kenzi enlists Dyson and Lauren's help on a case. They look into a woman whose legs were taken while she was swimming a pool. And it's creepy.
