In January 2003, while he and his son were out fishing, they found Beth Kane, washed up on shore after the car accident that killed her mother. They took her back to their home and when she woke up, Beth was immediately terrified, only wanting to see her father again. August tried to calm her down and explained that he wanted Beth to become friends with his son. She constantly screamed at him to allow her to go home, but he only left to get her a sandwich.

Later, while Beth and Johnny were watching television, a news report of her disappearance came on and she asked August why he hadn't called the police, however, he never answered but instead grabbed her and threw her into a room in his basement, and locked the door. She noticed a sink and when she looked into it, she saw a severed face floating in the water and fell backwards, disgusted. When August came down to take the face out, she asked what he was doing with it and he only said that it was an experiment. He then told her that the only reason she was here was to become friends with his son and that this was her new home. After he left, Beth desperately called out to her own father, wanting him to come and save her.

Beth later managed to open the door, making her way to the kitchen and calling her father. When he picked up, she asked him for help but was cut off by August grabbing the phone and ripping it off the cord. He warned her that if anyone came for her, he would kill them and proceeded to throw her back into her cell. Jacob and Kate Kane later showed up at the house, demanding to know where Beth was.

Season 1


  • August is an avid pipe smoker, which is why Beth nicknamed him "The Caterpillar".[1]
    • This is a reference to the Alice in Wonderland character named The Caterpillar, who is also known as The Hookah Smoking Caterpillar. Similar to Beth's kidnapper, the Caterpillar is mean to Alice in the story and is often very cryptic just like August's reasons for why he is holding her for most of the times seen in the flashbacks.

Behind the scenes

  • Mr. Cartwright was mentioned in the Gotham episode "Nothing's Shocking". He was the abusive husband to Victoria Cartwright and father of Jane Cartwright (whom Jonathan Cartwright is based on). Victoria eventually shot her husband in self-defence.
