This may not be the One Chicago show known for characters getting to be happy for too long without running into some obstacles, but Burgess and Ruzek got to be excited about co-parenting together for a stretch of Season 7, and that’s encouraging for how they could manage coming back together again some day.
At this point, Ruzek and Burgess do have the longest-running will-they/won’t-they relationship of the series, and it’s hard not to hope that they eventually get a stable status quo with each other on Chicago P.D..
