Dr. Archer has always been an intimidating presence on “Chicago Med,” but viewers have gotten a different side of him lately now that his son has reentered his life. The two hadn’t spoken for 15 years, and when Sean comes back into the picture, he’s dealing with addiction and prison time. At one point this season, Sean suffers an injury from another inmate and goes to the hospital where his father works, resulting in a crisis of faith where he doesn’t know if he should be the one to operate on his own son.
It’s made for some memorable moments this season, but some eagle-eyed fans may have thought Sean looked a little familiar. The actor, Luigi Sottile, doesn’t have a ton of credits to his name, but prior to appearing on “Chicago Med,” he had a one-off role on its sister series, “Chicago P.D.” as Larry Wozniak. On Season 6, Episode 5, “Fathers and Sons,” Sottile had a small part, but he obviously made a good impression on someone to land a much juicier role on “Chicago Med.”
Sottile finds himself in good company among actors who have played multiple roles in the “One Chicago” universe, and hopefully, he gets a chance to stick around a little while longer.
