The machine in Elias's basement smells like hot copper and Mara's perfume. That's impossible. She's been dead nine months. He keys in the date: three years ago, the morning of the crash on Route 9. He has practiced this a thousand times. Stop the car. Stop the truck. The coil screams and white light swallows the room. When he opens his eyes, he's in the passenger seat of their old sedan, and Mara is alive, humming, hands on the wheel.

Elias freezes. Seeing her breathe, hearing her hum, it's too much. He forgets the truck, the plan, everything. He just reaches over and holds her hand. The car keeps rolling toward the bridge in the rain. Mara smiles at him, confused but warm. 'You okay?' Up ahead, headlights swing wide across the wet lane.

At the last second Mara jerks the wheel herself, instinct kicking in. The car spins, clips the rail, and stops. They're both bruised but alive. She's shaking. 'I don't know why I turned. I just felt like I had to.' Elias realizes some part of her remembered the crash too. The past isn't as fixed as he thought.
