The dead returned in more ways than one on Lost Girl Season 4 Episode 11.
This was a strange episode. It felt like the writers had a hodge podge of ideas that individually wouldn't support a full episode so they mixed them all up together and we got "End of the Line."
It felt even more odd because Rainer was no where to be seen. He's supposed to be Bo's life now, but he took off on his own mission.
