Peter Mills is currently living in North Carolina with his mother and sister, running their own restaurant. Introduced in Season 1 as the new Fire Candidate on Truck 81, Mills has proved himself to be a determined and skilled firefighter. He was eventually transferred to Rescue Squad 3, however due to illness was transferred to Ambulance 61 as he was not cleared for firefighter duty. He was eventually reinstated as a firefighter and transferred back to Squad 3, where he later decided he did not want to be a firefighter and wanted to be with his family in North Carolina.


Mills' father was also a firefighter, but was killed after he and Boden rushed into a burning building against orders. His mother and sister owned and operated a diner, where Mills occasionally worked while off-duty. The diner was eventually destroyed by a fire set by Kevin Hadley. At the end of Season 1, Mills applies to the Chicago Police Department academy, suggesting that he plans to leave Firehouse 51 after finding out Boden and his mother once had an affair.


Mills and Gabriela Dawson share a love of cooking, which brings them together in the kitchen often. On one occasion, they share a home-cooked meal as 'friends' which ends up being much more. The two start a secret relationship, then later on decide to come out as a couple. However, Mills breaks off their relationship after Gabriela reveals to him that she knew about his mother and Chief Boden, Mills feeling as though he cannot trust her. Mills attempts to reconcile with Gabriela if she can assure him that she has no feelings for Matthew Casey, when she admits that she can't their relationship seems over for good. Even though Mills and Dawson's relationship is over, they still maintain a good working relationship and friendship.
