After a very successful first season, the Chicago Fire Season 2 took things to a completely new level. There is so much depth the characters and the stories inside the world of Chicago Fire. The local police force became such an incredible piece of the layered world that a spinoff was created, giving all of the characters even more room to breathe and grow. With only one series, you have to bring in recurring players who aren't already under contract. With two fully developed groups inside the city of Chicago, there are almost endless possibilities of what can happen. Chicago Fire Season 2 saw Casey struggling to cope with the death of Hallie, with a lot of help from Dawson. Guess what?! They're a couple now. Waiting on the sidelines has its rewards. Severide had an unwelcome visit from an old flame who tried to tell him he was the father of her unborn baby, while he was actively trying to plan a life that would give him his own child with his best friend Shay. Talk about bad timing! We saw the success of Molly's and Firehouse 51 became even closer than ever before. Enjoy Chicago Fire Season 2!
