What's Happened to Dr. Crockett Marcel on Chicago Med?

The trauma surgeon played by Dominic Rains came to Gaffney with plenty of skills, and a lot of secrets.

By Megan Lasher

Dr. Crockett Marcel (Dominic Rains) is one of the beating hearts of Chicago Med. As a surgeon at Gaffney Chicago Medical Center, he has saved the day more times than we can count, and he's also developed plenty of strong ties with his fellow coworkers. 

How to Watch

Watch Chicago Med Wednesdays at 8/7c on NBC and next day on Peacock.

But from his secret daughter to his unmentioned past as an immigrant re-named for a character in another Dick Wolf-helmed television show, the hard-partying doctor was always more than he let on (including to the co-workers with whom he developed romantic relationships).

Revisit Dr. Marcel's storyline below. 

When did Dr. Crockett Marcel join Chicago Med?

Dr. Marcel's first official appearance at Gaffney was in Season 5, Episode 1 ("Never Going Back to Normal"). The incoming trauma surgeon didn't make great first impressions with everyone, though: In Episode 3 ("In the Valley of the Shadows"), he and April Sexton (Yaya DaCosta) worked on their first case together and butt heads over the treatment plan.

In Episode 5 ("Got a Friend in Me") Marcel also argued with Dr. Ethan Choi (Brian Tee) over whether or not to perform surgery on a patient, making that relationship also difficult.

By Season 6, Marcel was typically pretty friendly to those around him, but he still hadn't open up about his life to either his fellow doctors or patients very often.

However, in Season 6, Episode 6 ("Don't Want to Face This Now"), he revealed that he'd had a daughter, who'd died at a very young age. A young patient was refusing care from the hospital because she was tired of being in medical environments after dealing with her mother's cancer treatments. Marcel related to her pain, and told her he had experienced the same thing. 

"I lost my daughter to Leukemia, about 10 years ago," he said. "Just a few months after her first birthday."

In Season 6, Episode 10 ("So Many Things We've Kept Buried"), he spoke to a patient in Farsi, and then talked about his childhood.

"My family moved here when I was two, we spoke Farsi at home," he explained. He later said that his birth name was Darioush Jahanbani, but his parents had changed their last name when the family moved to New Orleans so that he would fit in. The family patriarch, he said, chose "Crockett" as a first name for his son because he loved the show Miami Vice and its protagonist Sonny Crockett.

What happened between Dr. Cockett Marcel and Dr. Natalie Manning on Chicago Med?

A major part of Marcel's storyline in Season 6 was his relationship with Dr. Natalie Manning (Torrey DeVitto). The two originally began dating in secret but, in Episode 9 ("For the Want of a Nail"), Dr.Dean Archer (Steven Weber) was upset that Dr. Manning had gone to Dr. Marcel for a second opinion, undermining Archer's work on the case. He threatened to reveal their intimate relationship, and Dr. Manning told him, "We are professional colleagues, that's all you should be concerned about."

Throughout the season, Marcel began helping Manning with her mother's heart disease after Manning introduced the two in Season 6, Episode 11 (“Letting Go Only to Come Together”). But Manning's mother's illness tore her relationship apart, after Manning lied to Marcel about sneaking an untested drug into her mother's treatment.

At the beginning of Season 7, Manning departed Chicago for her hometown of Seattle and, at the end of Season 8, she was reunited with her long-time, on-again, off-again boyfriend Dr. Will Halstead (Nick Gehlfuss), who left Gaffney and Chicago to be with her and her son. 

Dr. Marcel and Dr. Blake's Romantic Relationship

In Season 7, the surgery team got a new leader in Dr. Pamela Blake (Sarah Rafferty). She began dating Marcel while acting as his mentor in transplant surgery techniques. However, the relationship took a serious turn in the Season 7 finale ("And Now We Come to the End") after Blake fell ill and put Marcel in charge of making decisions for her during a major surgery she needed.

He chose a surgical path that would save her life but risk the future use of her hands. When she woke up after the surgery, she cut him off for his decision.

In Season 8, Episode 20 ("The Winds of Change Are Starting to Blow"), Marcel was operating on a patient in O.R. 2.0 when the devices began to malfunction. As a result, the patient died on the table.

In the following episode ("Might Feel Like It's Time for a Change"), Marcel pursued answers over the death of his patient, but saw that the surgical file was missing from the machine's server. Jack Dayton (Sasha Roiz), Gaffney's new multi-millionaire owner, told Marcel that he'd hidden the file to protect the doctor from accusations of malpractice.

However, in the Season 8 finale ("Does One Door Close and Another One Open?") Marcel learned that the death was actually caused by an error in the machinery, and was relieved by the news.
