Luke chatted with Darcy for half an hour, and casually told her some things to pay attention to in an emergency drill as he used anecdotes to teach her.
The most important "three points of cowardice" were analyzed logically based on real cases in his detective career.
Darcy had no ability to resist a combo of Mental Communication, Basic Hypnosis, and Elementary Pheromone Control. When she ran into an unavoidable situation, her first reaction now would be to "follow the rules."
That could be considered a small compensation from Luke.
As long as she was cowardly enough, and instantly stayed far away from Thor, there was little chance of her being unlucky.
Luke couldn't do anything else.
Darcy had come out to earn credit with her teacher, Dr. Jane.
She was also a freshman at Yale, and was under a lot of pressure in her studies. That was why she hadn't taken a break for Christmas, and had followed her teacher out to earn credit.
