Peter Mills & season 1-3 OGs

I just started watching in November 2024 and I am now on Season 7. I think in the final season of this show they should bring back Peter Mills and he should be Battalion Chief of Firehouse 51, Matt Casey should be fire commissioner, and Severide should be fire chief or overall in charge if the OFI mannnn just promote everyone to the highest ranks possible 😂🤣 like gimme a full season of them in charge and end it with a happy ending LOL
