Klaus knew this was the most important moment, so he maneuvered throughout the area, avoiding the people looking for him. He managed to attract the attention of everyone around the area, clearing a large part through which Carion had to escape.
Klaus' mission was simple and effective: to pose as two people and clear an area. This was no difficulty for him, and he wouldn't even need to clear it completely. It was enough to attract attention for a while until Carion managed to get out of the controlled area.
And although he had many opportunities to flee, he did not. He had other plans.
After watching from afar as Carion left the area, Klaus smiled and looked at the houses.
