"A few episodes in the season we're going to meet her stepfather and discover they have a pretty complicated relationship. It's a theme we will hit pretty hard over the first half of the season," show creator Rob Doherty told TV Guide back in November 2015.

The official synopsis of the episode reads:

"When Watson's stepfather (John Heard) writes a crime novel based on her work with Holmes without her knowledge, an underlying issue in their relationship is revealed. Also, as Holmes and Watson investigate a retired FBI agent's murder, they discover the man's death is connected to an unsolved case from the victim's career."
