The two girls spent an hour connecting small wooden pieces while Evan worked on a customer's truck. Claire sat in the office with a cup of tea, watching Mia concentrate on something other than danger. The bridge held for thirty seconds before the center sagged. Mia laughed, genuinely and without looking over her shoulder.
Claire had not heard that sound since the dinner in Traverse City. She pretended to check her phone so nobody would see the tears filling her eyes. Evan noticed anyway and said nothing.
At Northstar, Dr. Patel revised the warning system's test procedures. The company installed prototype sensors on a dozen commercial vehicles used on rural routes, each with drivers trained to treat alerts as uncertainty rather than certainty. Evan's contract required him to document poor weather and observe where the system succeeded, failed, or distracted drivers.
His first weeks of testing frustrated him. One sensor repeatedly identified fence posts as possible pedestrians. Another worked well in open rain but failed when reflected light came from wet asphalt and a curve. The software showed a green status indicator when it detected nothing, even when poor visibility meant it could not see enough to make a reliable determination.
Evan asked Patel why the screen showed green. She explained it meant no hazard had reached the system's confidence threshold. He pointed out that drivers would reasonably read green as safe.
"That's not what the machine knows," he said. "It knows it didn't find anything. That's different."
Patel agreed to test a neutral gray status when visibility was uncertain. The change reduced the sense of confidence the product generated in demonstrations, but it made the display more truthful. The engineering team began measuring missed detections as openly as successful ones.
Claire's board worried about the effect on sales. A competitor advertised an almost perfect success rate without clearly describing its weather limits. Northstar's new material listed what it could and could not reliably identify. One director accused Claire of turning a commercial product into a memorial for her daughter's fear.
Claire listened, then answered carefully. "If the system cannot perform under conditions customers are likely to encounter, our duty is to say so. Mia's experience made me ask the question. The answer has to stand independently of what happened to her."
The board appointed independent engineers to oversee validation and kept Claire from making the final technical decision. She supported the arrangement. It was another lesson in the difference between caring deeply about an outcome and being entitled to control it.
The criminal case against David Bennett progressed on a separate track. His defense attorneys argued that the confrontation had grown out of a family dispute, and early public statements described Mia's removal from the car as a misguided attempt to protect her from adult conflict. Prosecutors used the garage recording, the phone messages, and Claire's emergency call to show how far that explanation was from the evidence.
