Cooper races home after Lexi warns him about a strange document on Debbie’s computer. Cooper now accepts that something is seriously wrong with Debbie and fears she may be punishing people she believes have harmed the family, including possibly Cooper himself.

At home, Lexi and Izzy are waiting anxiously. Lexi says Debbie told her she had fixed Lexi’s problem after school, which makes Lexi believe Debbie caused Zane’s accident. Izzy is also worried about Debbie, though Izzy admits she is not upset that Coach Pike is in jail.

Cooper opens Debbie’s desktop computer with Lexi’s help and finds a folder titled Dear Debbie. The files contain advice-column drafts, but the answers are disturbing rather than domestic: one response tells a woman to strangle her husband with a scarf. Lexi says most of the files contain instructions for killing husbands, forcing Cooper to question whether Debbie has become dangerous toward him.

Cooper calls Debbie, but she does not answer. Cooper leaves a tense voicemail asking Debbie to call and warning her not to do anything stupid, which alarms Lexi and Izzy further. Lexi then shows Cooper that Debbie’s Findly app stores recent location history, not just live location.

Cooper reviews Debbie’s past stops and sees expected places such as the school, grocery store, Titan Fitness, Robert Pike’s house, and the Hingham Shipyard. Then Cooper notices two locations that do not fit and is visibly shaken. Cooper calls someone from his favorites, gets voicemail twice, and abruptly leaves the house without telling the girls where he is going, hoping his fear is wrong.
