Jason was seen in Carry Their Legacy, when Squad 3's truck broke down and Squad 6 responded to the call in their place. They then came by firehouse 51, and it was revealed that he and Casey were very good friends. The next shift, Truck 81 responded to a distress call by Squad 3. Casey went down a tunnel that Squad 6 had been tending to because of a risk of a gas leak. However, the team warns him gas levels are too high, but he refuses to come back out until he finds Jason and the others.
