When Chicago P.D. returns for Season 6 later this month, the unit will find itself in total disarray following the death of one of their own. Season 5 ended on a devastating note with Olinsky (Elias Koteas) succumbing to injuries sustained after a brutal stabbing while in jail on false charges. The tragic event left the team visibly distraught and it looks like those raw emotions will carry over into the new season.

"Al passing away leaves a lot of frayed emotions for sure. Everybody's dealing with it in their own way," Patrick Flueger told TV Guide. Added Jason Beghe, "It's like a piece of your heart is ripped off. But it's still beating and you still have responsibilities."

With Voight (Beghe) still reeling from the loss of his friend, it will be up to Antonio (Jon Seda) to step up and lead the unit. However, not everyone will agree with the way he's running things and that disagreement will splinter the group. "Some people feel that Antonio should have done something different in the handling of the whole situation and there's a lot of tension," Tracy Spiridakos explained. Things will get especially heated between Antonio and Ruzek (Flueger), with the two poised to come to blows this season.

According to Jesse Lee Soffer, the fragile state of the unit leaves its future up in the air. "It's gonna take some time putting all those pieces back together. And because the team is in such disarray right now, the team could break up. We don't know what's gonna happen," he said.

See how the gang handles Olinsky's death when Chicago P.D. returns Wednesday, Sept. 26 at 10/9c on NBC as part of a three-hour One Chicago block starting with Chicago Med at 8/7c.
