Here is everything we know about Sean O’Neal’s character arcs and potential plotlines. 

If you saw this week’s fifth episode, “Pink Cloud,” released on October 19, 2022, from Chicago P.D. Season 10, you may have noted that the Intelligence Unit takes on a wicked new investigation involving a human trafficking network. And it brings with it a new and unexpected foe in the form of the chief of police’s son, Sean O’Neal, played by Jefferson White.

The episode showed how Upton’s relentless pursuit of a missing adolescent girl leads the team into a dark web of human trafficking and how Chief O’Neal becomes engaged with the unit’s investigation when it becomes clear that his son, Sean, has a connection to the missing girl.

Who is Sean O’Neal on Chicago P.D.?

As highlighted by NBC Insider, it all begins when Upton (Tracy Spiridakos) responds to shots at the scene and finds a girl named Abby beaten and chained to a bed. But before she can rescue her, she’s beaten over the head and knocked out by an unknown perp. Later on, as she and the Investigative Unit continue their search for Abby at a trap house, she finds Sean there, too. 

He claims to be searching for Abby, too, because she attends his safe place center for kids. Eventually, we learn that Sean, also a former addict, is the new chief’s son. As the case progresses and the team uncovers a human trafficking ring, Sean continues to offer his help. But Upton becomes increasingly suspicious. By the end of the episode, she tells Voight she believes Sean is lying to them and is actually using his support group to traffic underage girls.

Who plays O’Neal?

Chief O’Neal’s son is played by Jefferson White. Some will probably recognize him as Jimmy from Paramount Network’s hit Western drama Yellowstone. He also starred in NBC’s thriller Blindspot. The actor told TV Line that Sean has lived a “very difficult life” struggling with addiction and has a “contentious relationship with his dad,” which we’ll see play out in the coming episodes.

He also talked about his character and what sets him apart from his PD peers. “He’s got access to communities that don’t necessarily trust the CPD because of the history and tension,” he explained. “Sean himself has a complicated relationship with the police, and that also means he has a completely different perspective on [the case].”

What’s next for Sean on Chicago P.D.?

Series showrunner Gwen Sigan told Cinema Blend that the Intelligence Unit’s new chief, Patrick O’Neal, and his son would be a part of an important storyline through to Season 5, Episode 9. She compared their arc to the dramatic saga Voight went through with his informant, Anna, who died in the Season 4 finale. 

“It will probably be very similar to last season where we had Anna, and her storyline really became serialized, and I would say probably six episodes of it,” Sigan said. “We’ll do a very similar thing this season. We’ve got some great standalone and great cases that we solve…[O’Neal] will be coming back quite a bit in the first half of the season, as well as his son, who is played by Jefferson White. We’re very excited to have both of them.”

Gwen Sigan also stated that Chief O’Neal and Sean would play a major part in the season through Episode 9. So this means we will see much more of the mysterious newcomer. Benjamin Levy Aguilar, who plays rookie Torres, also told NBC Insider that O’Neal and the trafficking case would become Upton’s sole focus. “She becomes obsessed with this case,” he tells us. “She’s the one who’s leading it.” 

Sigan previously told us that Upton would use work to distract from Halstead’s absence. “The reality is, she’s been left behind, and that’s gutting,” she said. “We’ll see her deal with it by first seeking distraction – diving into work, putting all that feeling into the job—and when a case pops off that really gets inside her head, that distraction quickly turns to an obsession. It’s an interesting path for her, fueled by a lot of emotion and denial.”
