Liv (Rose McIver), Detective Babineaux (Malcolm Goodwin) and Ravi (Rahul Kohli) work together in solving the murder of Chris Allred (guest star Jay Hindle), who was a high school shop teacher by day, and a vigilante crime-fighter named “The Fog” by night. Liv gets into trouble while on superhero brains and becomes a little too much for Clive to handle. Meanwhile, Major (Robert Buckley) has an eye opening conversation with a new friend. Lastly, Blaine (David Anders) forces Liv to do the unthinkable. Mairzee Almas directed the episode written by Diane Ruggiero-Wright (#209). Original airdate 12/8/2015.
