Chicago Fire Episode 3.03 Just Drive the Truck

A routine call sends Truck 81 out to a fire and en route they notice another fire truck driving parallel, on the way to the same fire - Truck 66 from Welch's antagonistic firehouse. Cruz hits the gas to ensure Truck 81 makes it to the scene first and they appear to leave 66 in the dust... until Welch's truck plows into 81 at an intersection in a catastrophic collision.

Dust, debris and bent steel lay everywhere - Severide leads Mills, Capp and Newhouse to help pry out the injured. Mouch sustains a major laceration on his eye, but everyone else emerges with minor cuts and bruises. Welch's truck, however, looks worse - one firefighter has a broken leg and the driver, Molina, is covered in blood and unconscious. Dawson and Brett help rush them to Chicago Med while Boden and Chief Tiberg grill Cruz on whether he had the light at the intersection. Still dazed from the wreck, Cruz submits to a breathalyzer as he assures Boden that he had the light. Casey supports Cruz, too, but also can't confirm whether the intersection light was green, yellow or red.

While helping with the rescue, Mills suddenly gets dizzy and drops to the pavement, now the second time he's passed out on the job. Severide snaps and demands that he see a doctor before his next shift, and when Mills complies he learns that he suffers from a form of vertigo, which means no ladders, no ropes... and no clearance for squad duty. Is this the end of his firefighting career?

At Chicago Med, Mouch receives good news - his eye will heal and his sight will return in due time. His luck doubles when Newhouse shows off a surprise acquisition - a food truck for Molly's II. Newhouse offers it to the Molly's II team under one condition: he wants in on the project as a partner. Seems like a win-win for Molly's.

Molina, on the other hand, remains in critical condition. Worse yet, Tiberg discovers video evidence that Cruz blew through a light just south of the crash. If Molina dies, Cruz could face manslaughter charges. Cruz reaches out to Welch, but Welch blames him for the crash and tempers flare - until Herrmann makes the peace by offering up Molly's as a locale to raise funds for Molina and his family.

More change is afoot when Casey informs Dawson that she can join Truck as the station's candidate, as long as she and Casey remain unmarried. Although excited to finally start fighting fires, she hesitates - this will mean postponing the marriage at least a full year. Plus, how will their relationship at work change as lieutenant and candidate? Dawson decides it's a risk worth taking, and Casey agrees. Boden makes the move official, which leaves an opening slot for a paramedic - a position Mills mentions he could fill.

But first, Mills rekindles an interest in his father's family following some encouragement from Boden. He finds his grandfather Leonard at a nursing home, wheelchair-bound due to cancer. The meeting starts off awkward, but Leonard's sudden smile quells Mills' fears of lingering racism. They hug - family at last.

Another family receives a stroke of good fortune at Chicago Med when Molina wakes up. He admits to following a silent order from Welch to beat Truck 81 at any cost, and his statement exonerates Cruz. The two fire truck drivers share a moment together, with Molina's brush with death clearing his mind of any animosity, ready and willing for him and Welch to accept the consequences of their dangerous actions.
