Episode 11 of "High Potential" kicks off with a dramatic confession from George Donovan, the head of a prominent and affluent family, who, on his deathbed, admits to slaying his son-in-law, Barry, a decade prior. Barry was discovered deceased in the sauna, yet George managed to dodge culpability thanks to a bizarre defense strategy that implicated a nearby drug addict as the perpetrator who broke into the mansion and committed the murder. This bombshell revelation propels Selena into action, prompting her to revisit the cold case and enlist Morgan's expertise to uncover any overlooked evidence.
Morgan dives into the case files with meticulous scrutiny and concludes that Donovan did not pull the trigger. Instead, she formulates a theory that Barry met his demise via electrocution, likely facilitated by a vintage 1980s hairdryer found in close proximity to the bathroom. Her deductions suggest that the body was dumped down a laundry chute, explaining the presence of Barry's blood on George's shirt. The broken neck and the sauna setting were part of an elaborate staging job, mimicking an accidental death.
Upon visiting the Donovan residence, Morgan, Selena, and Karadec stumble upon scorched electrical switches, validating Morgan's predictions. Shortly thereafter, the family returns, recounting the tumultuous evening preceding Barry's demise, with George expressing repeated dissatisfaction towards his son-in-law.
Enter Nedda Donovan, George's estranged daughter-in-law, who arrives at the precinct to discuss her ongoing documentary about the murder. She uncovers a startling revelation: during a family dinner, Heather, George's daughter and Barry's wife, mysteriously caught fire, leading to the discovery of bruises on her arms, which exposed Barry's history of domestic abuse. This revelation casts a dark shadow over the family, revealing a potent motive for one of them to eliminate Barry.
The investigative team interviews each family member individually, pinpointing Matty and Clarke as having had sufficient opportunity to commit the crime. Meanwhile, Nedda clarifies that the drug dealer had actually come to see Matty, Heather's brother, rather than Barry.
Just as tensions mount, the police captain arrives at the Donovan mansion, having been briefed about Selena and her team's renewed investigation.
Morgan, who has been methodically connecting the dots, finally identifies the culprit – Cody, Barry and Heather's son. Cody, aware of his father's abusive behavior towards his mother, took matters into his own hands. While Barry was in the shower, Cody electrocuted him and meticulously staged the scene. He even employed radio frequency remotes to flick TV channels, creating the illusion that Barry was still upstairs alive and kicking. In a heart-wrenching confession, Cody admits to the crime, revealing that his grandfather had shielded him from the consequences. Cody is subsequently arrested and will face trial as a minor, given that he was only 15 years old at the time. Case closed, but not without leaving a profound impact on all involved.
