Spying?
Sarah looked at her daughter thoughtfully. "Daughter, you should focus on the blood transfusion only and avoid doing dangerous missions, please don't wear out yourself, you are doing too many things at the same time, you should have let the king and his men do the rescuing while you focus on blood transfusion and have a good rest in between," she said.
Jessy smiled fondly at her mother. "That's what I've been doing, Mother. I just rescued the mortals, it was an easy thing to do, and the king and his men do the killing for me, I did not kill a single soul last night—I swear!" she said seriously.
"Then—how many people you killed so far, Jessy?" Sarah asked her daughter the question without even batting an eyelash. She saw the dark cloud covering her child's eyes quickly. She can't monitor her going out of the Facility all the time and this got her worried. "Tell me, child," she said in a calm voice not wanting to alarm her.
