Over the years, Chicago P.D. has built its reputation on tension, loss, and unforgettable exits. Characters come and go, some quietly, others leaving scars that still haven’t healed. But if I had to choose one character I love the most — and want to see return more than anyone else — the answer is clear.
Alvin Olinsky (Eamonn Walker)
Yes, that Olinsky.
Even years after his heartbreaking departure, Alvin Olinsky remains one of Chicago P.D.’s most emotionally irreplaceable characters. He wasn’t just part of Intelligence — he was its moral anchor, the quiet strength behind Hank Voight, and the father figure no one else could truly replace.

Why Olinsky Still Matters
Olinsky didn’t need dramatic speeches or explosive moments to command the screen. His power came from restraint — from loyalty that ran deeper than rules, and compassion that survived in a world built on violence.
When Olinsky left, Chicago P.D. didn’t just lose a detective.
It lost balance.
Voight has never been the same. Intelligence has never felt as grounded. And the show itself grew darker — more ruthless — without Olinsky there to pull it back from the edge.
A Return That Would Change Everything
Let’s be honest: Chicago P.D. has never been afraid of bending reality when it serves the story. Whether through flashbacks, hidden truths, or long-buried secrets, bringing Olinsky back — even temporarily — would instantly raise the emotional stakes.
Imagine:
-
Voight forced to confront his past choices
-
Intelligence facing unfinished business
-
The ghosts of loyalty and sacrifice resurfacing
It wouldn’t just be fan service.
It would be storytelling at its most powerful.
Why Fans Still Talk About Him
Years later, fans still ask the same question: Why did it have to end that way?
That alone proves Olinsky’s impact hasn’t faded — it’s grown.
In a series built on loss, some absences hurt more than others. And Olinsky’s absence still feels like an open wound.
Final Thought
Chicago P.D. may have moved forward, but part of its soul remains unfinished.
💬 If you could bring back one character, who would it be — Olinsky, Erin Lindsay, Antonio Dawson, or someone else entirely?
Because in the world of Chicago P.D., some characters never truly leave…
They just wait for the right moment to come home.
