Without giving away major spoilers for those still catching up, Episode 3 pivoted heavily on the medical and emergency service aspects of the case. Usually, detectives like DS Lisa Armstrong (Morven Christie) or DS Jenn Townsend (Marsha Thomason in later series) deal with the aftermath. However, this episode forced the characters to confront the immediate, chaotic reality of the emergency services.
For Lisa Armstrong, this episode was a turning point. Her determination to get to the truth, even when it meant clashing with medical protocols or her superiors, highlighted her complex morality. She isn't a superhero; she’s a dedicated professional working within a flawed system, trying to do right by the victims. the bay s02e03 amr
