Season two opens with the lives of the doctors at McNamara/Troy in a state of turmoil. Sean McNamara is struggling to keep his family together after learning his wife, Julia, had an affair with his best friend and partner, Christian Troy. The revelation has shattered their marriage, and Sean is now living in an apartment, attempting to co-parent their young son, Matt, while dealing with profound betrayal.
Christian, meanwhile, is attempting to embrace a more conventional life. He is in a committed relationship with the model, Gina Russo, and has formed a deep bond with her young son, Zac, whom he begins to see as the son he never had. This domestic stability is a stark contrast to his former womanizing ways, but Christian’s old habits and the shadow of his betrayal to Sean continue to haunt him.
The season introduces a major new threat in the form of The Carver, a mysterious and sadistic serial attacker who targets beautiful people, scarring them with a knife and uttering the chilling phrase, “Tell me, what don’t you like about yourself?” This villain terrorizes Miami, creating an atmosphere of fear and suspicion that eventually strikes close to home, impacting the doctors and their circle directly.
Personal dramas escalate as Matt, Sean and Julia’s teenage son, becomes increasingly rebellious. His relationship with the much older escort, Ava Moore, intensifies, leading to devastating consequences. Julia, adrift after the collapse of her marriage, begins a new relationship with a woman, exploring her sexuality further, which adds another layer of complexity to the family’s dynamic.
The professional world of the surgeons is also upended by the arrival of Dr. Quentin Costa, a charming and talented new plastic surgeon who joins the practice. He forms a fast friendship with Christian, but his motivations are murky. It is eventually revealed that Quentin is the infamous Carver, using his position to select and stalk his victims. The season builds to a tense climax where Christian, having discovered the truth, is attacked and brutally carved by Quentin.
The season finale leaves several fates hanging in the balance. Christian is left physically and psychologically scarred. Sean, in a moment of desperate heroism, kills Quentin to save Christian, binding the partners together with another dark secret. As the dust settles, the two men sit amidst the wreckage, their friendship and partnership forever altered by violence and trauma, unsure of how to move forward.
