Do No Harm

Dr. Jason Cole is a highly respected neurosurgeon who has it all - a lucrative career, confident charm, and the gift of compassion. But he also has a deep, dark secret. One morning, when he wakes up disoriented in a wrecked hotel room amidst several near-naked women he's never seen before, he knows one thing: it's happening again. Every night at the same hour, something inside Jason changes, leaving him almost unrecognizable - seductive, devious, borderline sociopathic. This new man is his dangerous alternate personality who goes by the name of "Ian Price."

Jason's attempt to control Ian's spending backfires when the doctor comes to in a random sports car tailed by a drug dealer. Meanwhile, a falling out between Jason and Lena prompts a late-night visit from Ian; Dr. Jordan tries to get to the bottom of Jason's behavior; and Olivia worries about her son's new imaginary friend.

Jason agrees to grant Ian his wish - a rendezvous with the object of his desire, Olivia. But it comes with a catch: Ian must pose as Jason at a black-tie event honoring Dr. Vanessa Young.

Ruben arranges for a gang to "mug" Ian so that he can get a sample of his spinal fluid -- a necessary element for his pending kill drug, but the plan backfires when Jason is blackmailed by the gang into potentially killing a patient who is a member of an opposing gang.

When a surgery's complications force it to continue after 8:25pm, Jason (Steven Pasquale) chances taking Ruben's (Lin-Manuel Miranda) still-unfinished kill drug to hold Ian (also Steven Pasquale) off long enough to finish the surgery. The surgery is a success, but the drug doesn't last as long as planned and both Lena (Alana De La Garza) and Olivia (Ruta Gedmintas) suffer as a result.

An operation on Jordan's son is made even riskier by Jason's ingesting of the unfinished kill drug, which makes Ian's appearances more random than usual.

Jason, now aware that he has a son, desperately wants a relationship with him, but Olivia feels it's too dangerous and painful. We learn the backstory of how Jason once saved Olivia from Ian and from herself. Meanwhile, both Ruben and Lena start to question Jason's practices.

In a desperate attempt to keep "his" son from Jason (Steven Pasquale), he kidnaps him and hides him from both Jason and Olivia (Ruta Gedmintas). Meanwhile, Ruben (Lin-Manuel Miranda) closes in on the kill drug but isn't sure if he should use it - and, if so, who of Jason or Ian (also Steven Pasquale) he should use it on.

After Jason (Steven Pasquale) collapses in front of Dr. Young (Phylicia Rashad), an MRI reveals Jason has a brain tumor - Jason and Ruben's (Lin-Manuel Miranda) plan has worked, the "tumor" surgery will act as a cover for Ruben's implant to destroy Ian (also Steven Pasquale) once and for all but Lena (Alana De La Garza) may soon discover the truth and put a stop to their plans. Meanwhile, Ian has no intention of going down without a fight and will stop at nothing to save himself.

Jason's (Steven Pasquale) brain surgery is about to begin, a neurotransmitter implant that will "cut out" Ian (also Steven Pasquale) for good, however due to the blackout drug he has taken for years, Jason is immune to the normal anesthetic. A much stronger drug is given to Jason and in the midst of his twilight sleep he flashes back to his childhood and the origin of Ian Price is finally revealed. Meanwhile, Jordan (Michael Esper) and Lena (Alana De La Garza) are on separate tracks to uncover Jason's secrets all of which could prevent the surgery's completion.
