Chicago P.D., NBC’s gritty police drama, has enthralled viewers since 2014 with its raw depiction of Chicago’s Intelligence Unit. At its heart lies the romance of Kim Burgess and Adam Ruzek, affectionately dubbed “Burzek,” whose journey culminates in the Season 12 finale, a two-part spectacle aired in April 2025. This episode, blending high-stakes action with a long-awaited engagement, showcases why Chicago P.D. remains a must-watch on Peacock, drawing fans globally with its emotional depth and thrilling cases.

The Season 12 finale, titled “Sweet Vows,” centers on a citywide crisis orchestrated by corrupt Deputy Chief Charlie Reid. The Intelligence Unit, led by Sergeant Hank Voight, races to stop a bombing plot, with Burgess and Ruzek at the forefront. A standout scene sees Burgess defusing a bomb in a crowded hospital, her hands steady despite the ticking clock, while Ruzek provides cover during a shootout. This heart-pounding moment, shared on X by @SmScreenQuotes, sparked fan frenzy, with posts praising Marina Squerciati’s portrayal of Burgess’s courage. The tension mirrors Burzek’s relationship—tested by danger but fortified by trust.

Burzek’s romance, spanning 12 seasons, is a slow-burn masterpiece. From their Season 1 flirtation to surviving losses like their miscarriage in Season 3, they’ve faced it all. The finale’s emotional peak occurs when Ruzek proposes on a Chicago rooftop, the skyline glowing behind them. “You’re my home, Kim,” he says, a line that trended on X for days. Fans, as noted in a 2025 ScreenRant article, called it “the payoff we waited years for.” Their engagement, sealed with a kiss, blends vulnerability and strength, resonating with viewers who see them as a beacon of hope.

The episode’s action—car chases, undercover ops, and Voight’s strategic takedown of Reid—keeps pulses racing. Yet, Burzek’s personal moments, like their quiet exchange about adopting Makayla, ground the drama. This balance of adrenaline and heart makes Chicago P.D. accessible to new viewers while rewarding loyal fans. The show’s diverse cast, including LaRoyce Hawkins as Kevin Atwater, adds depth, with subplots like Atwater’s mentorship of a rookie cop weaving into the main narrative.

Burzek’s real-life chemistry, fueled by Squerciati and Patrick John Flueger’s friendship, shines through. A February 2025 interview revealed Flueger hosted Hawkins for Thanksgiving, mirroring their on-screen bond. This authenticity draws viewers to Peacock, where all 12 seasons stream. Posts on X, like one from @ChiPD_Fanatic, urge fans to “binge Burzek’s journey from the start.” Whether you’re drawn to action or romance, Chicago P.D.’s Season 12 finale delivers, making Burzek’s love story a global phenomenon.
