It was revealed in "The Reckoning" that Lisa Campbell was a mole planted inside the FBI by Eliza, who was part of a sinister organization. Lisa planted a tracking device on Ryan Hardy's vehicle, which led to Eliza finding him with serial killer Theo Noble. After Lisa and Eliza talk on the phone, the former leaves with Max Hardy to follow Theo's trail, with Max unaware of Lisa's true role. Max tells Lisa to call for back-up, but in unbeknownst to Max, the villainous Lisa took out her gun with intent on killing her. Lisa is later taken by Theo and forced to co-operate with him, and she is later found by Ryan and Max with a gunshot wound. At the end of the episode, Ryan finds Lisa hospitalized and confronts her over her actions, which led to the deaths of several agents. Lisa talks about how some serial killers are protected and have large financial means to commit their murders, but she does not give Ryan any information about Eliza or her organization. She is later (assumingly) killed by Ryan.
