Lost Girl returned to the true heart of the show in "The Kenzi Scale:" The friendship between Bo and Kenzi.
Instead of Bo and Kenzi's friendly banter sessions to open each episode, Lost Girl season 3 has spent more time on Bo's romantic and sex life.
In "Fae-de to Black," Bo basically shunned Kenzi and at a time that her friend needed her the most. The outcome was that Kenzi was abducted and replaced by Faux-Kenzi. It was only then that Bo remembered how much she cared about her friend.
