Martin Howard walked ahead, with Schultz right beside him. As for the dog taken hostage, it was left at home, and consequently, Kate also had to stay behind at Martin Howard's house.
They were short on hands, and it was impossible to make other arrangements, so Schultz had no choice but to accompany Martin Howard alone to the supercomputer center. The dog named Cody was the crucial reason Martin complied, and if both Kate and Schultz went to the supercomputer center, leaving the dog alone at home, there was a high chance Martin would risk everything. Therefore, they had to split up.
Schultz wore a pullover and a mask on his face. Carrying his computer on his back, he followed inconspicuously beside Martin Howard.
