Escape
When the invisible force field pushed Jack back, it made a kind of light, yet bubbly sound. It was as if Jack had thrown himself into an elastic wall and was bounced back. Besides the shock of being thrown back so suddenly he was fine.
His grimace, however, was extremely ugly. Clearly there was no information about Jessie gaining access at the same time as Nero and the rest. Although that did not automatically mean she was an enemy, Jack did not think trust her at all.
Arter also frowned, but did not do anything drastic. He still believed that since she had been selected by his family, she was on his side.
But before the situation could develop further, the force field made the same sound. For a moment Nero felt like Vanessa had returned, possibly to taunt Jack, most likely because she had immediately encountered some kind of unexpected obstacle.
