When Mary's next-door neighbor mysteriously goes missing, she and John start digging into the disappearance. During their investigation, John unexpectedly reunites with someone from his past. Carlos and Ada bond as they stakeout a potential lead for the demon's partner. Meanwhile, Latika taps into old folklore passed down from her family in hopes it helps Mary and John.

Hidden secrets from Ada's past comes to light when the gang goes undercover to look into a suspicious death. Still reeling from the last Hunt, Millie asks Mary to keep an eye on John as they split off from the others to get intel on the new case. Carlos and Ada's stakeout connects the victim to the next target. Latika's research comes up with some interesting results that lead John to be Mary's lifeline out of a sticky situation.

When Vampires make their way into Lawrence, Carlos corrals the gang to find out why. Latika's weeks of sorting through the Men of Letters clubhouse provides vital information when John gets a scary glimpse into the future and enlists Millie's help with his plan. Meanwhile, Mary struggles with the tedious balance between feelings and action when it comes to John.

In the aftermath of the fight with Golem, Carlos, Mary and Latika are cleaning the clubhouse when they hear a noise from outside. They creep out to investigate and spot a figure but can't quite make it out until it turns, and they are shocked to see John standing before them, covered in blood. Meanwhile, Carlos and Latika set out in search of something important.
