A clerk tries to activate the headphones, with no success. He indicates that he is ready to go to the food court. He wants a Coke with no ice and extra straws. The Dynavox tape omits these details, so Babu makes a note to reprogram the machine after this trip. When the Coke is a mere memory, Hugh is ready to return to the van.
Time is of the essence.
If the trip back takes too long, Hugh may miss his school bus. A trip to the mall. Better yet, he's gained a bit of self-confidence and a feeling of independence. Dougherty and Babu will review his progress and plan for Hugh's next outing.
