Heather Darden was the wife of the late Andrew Darden. She and Andy have two kids, both boys, Ben and Griffin. Heather blames Kelly Severide for her husband's death because she thinks that he is the reason why Andy became a firefighter.
Heather was married to Andy Darden until he was killed in action in the pilot episode. After this she remain close to Matthew Casey, however she believes that it was Kelly Severides fault that Andy was killed.
After Andy died, Heather began to get even closer Matthew Casey, kissing him in his car and later sleeping at his house. When Casey says that it is not right them starting a relationship due to the fact that Andy and his were so close she agrees, although asks why they can't just be happy. She later begins to be civil with Severide, as she is starting to see that it was not his fault.
In season 2, on the anniversary of Andy's death, Heather went out drinking with some of her friends. At the firehouse, they were alerted to a car accident and when they arrived at the scene they were told that the driver was drunk and has been arrested and the passenger is in critical condition. Casey recognises the passenger as one of Heather's friends and realises that the drunk driver is Heather. Heather is currently in prison for 15 months for manslaughter, as the passenger of the car died. Griffin and Ben are currently living with Casey until Heather is released from prison.
