"Chicago Fire" on NBC is a popular series that is watched by millions of fans. When it returned for its sixth season on September 28, it came back with a vengeance. Every episode has been extremely intense not only with fighting fires but with the stories of the firefighters' personal lives.

There is no shortage of dangerous situations the firefighters and paramedics face at Firehouse 51 of the Chicago Fire Department. Even when the dangerous situations end successfully, there are the personal struggles that have to be dealt with. In this current season, there are two work-related situations that have humanized the series, not that it hasn't had many personal issues in the past.

Captain Casey

Fans love Matthew Casey, played by Jesse Spencer, who has just been promoted to captain. He has always taken pride in performing his job well and doing the right thing in controversial matters. In last week's episode, it was sad to see him at odds with his best friend Kelly Severide, played by Taylor Kinney. Hopefully, they can come to some common ground because fans love them both and don't want to choose sides.

When a young man was caught in barbed wire, Kelly offered a suggestion that Casey used his authority to override. Because Casey didn't listen to Kelly, the young man's leg had to be amputated. It seems that Casey is rethinking his new position as was indicated when he was seen having a serious conversation with Chief Wallace Boden, played by Eamonn Walker.

Casey's wife is sensing that his job might affect their marriage. Since she works along with him, she is noticing some things that were not there before he became captain. Hopefully, Casey can work this out because he and Dawson, played by Monica Raymund, are such a loving couple.

The new girl

Hope Jacquinot, played by guest star Eloise Mumford, is deliberately out to taunt Stella Kidd, played by Miranda Rae Mayo.

Hope withheld Stella's paycheck which put Stella in a bind for paying her bills. Hope insisted a check did not come in for Stella. She spent time on the telephone and going in person to payroll to get a replacement check.

Hope is seen giving Stella a new check which made Stella happy. Stella regretted she had been so hard on Hope when she thought the new girl had taken her check.

However, at the end of the episode, Hope is seen shredding Stella's original check that she had all along.

Since Mumford is a guest star, she will probably be found out and fired from the firehouse and will leave the series. "Chicago Fire" airs Thursdays at 10 p.m. on NBC.
