What can we learn from Chicago Fire season 6? Here are the three lessons we learned from Chicago Fire’s recently completed season.

As we continue to look back at this season of Chicago Fire, it’s worth looking at the things we learned or took away from the events of Chicago Fire season 6.

The sixth season was a busy one both on and off screen for NBC‘s first One Chicago series. We said goodbye to co-creator Michael Brandt and found out that Monica Raymund was leaving as well.

In between, we saw promotions, attempted promotions, a shooting, an almost being shot, and a couple of breakups and getting togethers plus the season’s only crossover. So what conclusions can we draw from all of that?

Here’s what we learned from Chicago Fire season 6:

1) Never trust anyone from your past

Did anyone notice that all of the major thorns in our team’s side this season were characters with ties to someone’s past?

Hope Jacquinot (Eloise Mumford) was a childhood friend of Sylvie Brett (Kara Killmer) before she was hired and fired at Firehouse 51.

Chief Carl Grissom (Gary Cole) was a mentor of Kelly Severide (Taylor Kinney) and a friend of his father’s before he started making life difficult for Severide and was exposed as a fraud.

And though not a bad guy, Jake Cordova (Damon Dayoub) was Gabriela Dawson’s (Monica Raymund) ex before he showed up at the firehouse and made her life uncomfortable for a few episodes. Ditto Renee Royce (Sarah Shahi) and Severide.

So the lesson here is, if somebody from the past resurfaces at Firehouse 51, move very quickly in the other direction and don’t look back.

2) People can actually get promoted at Firehouse 51

We were starting to think the rest of the Chicago Fire Department had a grudge against Firehouse 51 with how most of upper management seemed to always show up annoyed about something. After all, this was the season after the season in which Deputy Chief Anderson tried to disband the entire house!

But Matthew Casey (Jesse Spencer) actually earned a surprise promotion to Captain near the start of the season, and for a while there, Chief Wallace Boden (Eamonn Walker) was looking forward to a promotion of his own before briefly running for fire commissioner.

Though there’s a limit to how much the show can do for story reasons, it was nice to see this season finally throw some kudos our way given how hard these characters work and how they’re supposed to be so good at their jobs. There wasn’t a good reason why people hadn’t moved up the ladder by now.

3) You can hide a lot of things in a firehouse

Chicago Fire‘s firehouse has always been a hot spot for all kinds of activity, but the sixth season took that to a new level and taught us just how much you can fit into a firehouse other than the actual firefighters and paramedics.

Found hiding inside the walls this season: Joe Cruz’s (Joe Minoso) brother Leon (Jeff Lima), who was smuggled in for a surprise reunion; the ill-fated guinea pig who escaped last season and did not survive in this one; and several members of the FBI, as you can revisit by playing the video above.

It’s almost a running joke at this point how many non-firefighting people and things end up finding their way into the firehouse, but Chicago Fire season 6 definitely made particular use of that idea to come up with a few plot twists. Though we’re still sad about Mr. Sprinkles.
