It’s not just the ensemble of Chicago Fire that has changed over the last 12 seasons as old cast members exited and new ones joined the fray. The NBC drama’s characters, too, have evolved over the years in their job titles, marital statuses and personal arcs.
Below, TVLine is looking back at how the most recent crop of firefighters and paramedics has grown, from personality traits to major life changes, in the time from their first episodes (pictured on the left below) to now (pictured right below). And considering how long the hit #OneChicago show has been on the air, it’s no surprise that there have been some big transformations.
But first, some notes about who’s included and who’s not: In addition to the current cast, we’ve selected a couple of characters who made return appearances last season to offer viewers an update on their lives (Casey) or who only recently exited the series (Brett, Boden). Not featured are all those whom we loved and lost, but you can relive their tragic deaths here. And since we haven’t gotten an update on Gabby Dawson in a long time, we’re just going to assume that she’s still rocking the medical aid work.
