The way each knight serves his lord is different. Catherine's method may seem foolish, but it is by no means wrong.
"Carl may be in danger. Are you still going to stay like that?"
At Nero's words, Catherine took out a pocket watch from her jacket and checked the time. Then, she replied calmly,
"There is still time left until the time Carl mentioned. When the time comes, we will move to find him."
"..."
Nero's eyes became dizzy from Carl's manipulations.
Carl had created a safety device by even telling her to come find him if it was too late.
It was not a safety device for life or death, but a safety device as the last bastion to avoid being treated as a child without an answer.
For some reason, Carl said he was obedient and compliant!
"Find Carl. Hurry!"
Nero urgently ran into the forest.
He knew for a fact that Carl probably never really went into the forest to hunt.
