When Lothur revealed the kart to the people in that hall, Frederik immediately jumped out of his seat and ran to that item.
Seeing the final product he had helped to develop, he could not stand still and soon stood next to the kart, trying to make sense of this thing.
That was similar to what he imagined it would look like considering his imagination of how the constructed parts would fit together. But there were a few differences here and there, and what's more, seeing something finished was very different from imagining what an item would look like after the final production phase.
'So this is what it looks like? Seeing it this way, it looks like something promising!' He saw the small steering wheel there and felt curious about how this thing would move.
Other people besides Frederik also got up from their seats, looking in surprise at that item, but for different reasons.
