The March 24 episode of High Potential delivered a major twist in the Roman Sinquerra disappearance case, revealing Willa Quinn's alliance with Captain Wagner's father. Quinn attempted to outmaneuver investigators while pressuring the elder Wagner to remove Detective Morgan from Major Crimes. Meanwhile, tensions simmered in personal relationships amid a close call for Karadec.
In the March 24 installment of High Potential's second season, episode 16 brought significant developments in the mystery surrounding Roman Sinquerra's disappearance. Willa Quinn, the fixer suspected of hiring Eric Hayworth to kidnap Sinquerra, visited the LAPD precinct to speak with Detective Soto after returning from New York City. She denied links to Hayworth but proposed collaborating on the case, a move Soto viewed as an effort to silence Hayworth permanently. Investigators possessed incriminating messages between Quinn and Hayworth from the night of Sinquerra's vanishing, but Quinn alerted the FBI to Hayworth's alleged involvement in the death of agent Lila Flynn, prompting federal custody that blocked LAPD access. Later, Quinn met Wagner's father, portrayed by Clancy Brown, at a luxury hotel. Earlier, he had approached his son about recruiting Morgan for his congressional campaign, a request originating from Quinn herself. Quinn warned him, 'Do I need to remind you that we're in this together? I know where all of your bodies are buried. If I go down, you're coming with me. And you are right, we are going to have to figure out another way.' This connection suggests Quinn aims to sideline Morgan from Major Crimes using Wagner's father. Separately, Morgan and Karadec encountered an explosive art installation during an investigation, leaving Karadec hospitalized after shielding others. Upon waking, he initially mistook Lucia for Morgan and called her name. Morgan later visited with his preferred cookies—chocolate chip without the chips—sharing a synchronized response with him about their appeal over sugar cookies. Lucia later told Morgan, 'Thanks for being there, Morgan. You're a really good friend,' amid signs of strain, though Karadec and Lucia have exchanged 'I love you's and plan to buy a house together. Morgan questioned the pace of their commitment.
