On visiting the apartment, Adam finds the two bodies of a female and a kid, and a distant clatter distracts him from sight, which leads him to a room. The room is lit, and he finds a girl, Zoe, sitting at the study table. She is silent and reluctant to respond to Adam; however, he pacifies her and takes her out of the apartment to the police station.

At the police station, Adam swiftly tries to interrogate Zoe to understand what exactly happened at the apartment. Zoe refers to the lady and kid as her stepmother and sister. She also gives vital information about her father, Peter Cassidy. Zoe says that previous to this lady and kid, there have been other females and kids she and her father have lived with.

The evidence from the hospital helps them catch Thomas, who doesn't reveal anything about Zoe. Thomas kills himself in police custody, and the team relentlessly looks for Zoe. They find a note Zoe wrote with the word "mote" in it. They understand that she means a motel, and they reach an abandoned motel nearby.

Zoe is found in the motel, and the team brings her back. They run a DNA test on their historical data and find her match with an old lady, who turns out to be Zoe's grandmother, Amy. Amy reveals that Zoe's real name is Marie, and her mother was Thomas' first victim. She had been searching for her grand-daughter ever since Marie's mother died, and this brings Annabelle's role to an end in Chicago PD.
