Nox kept his calm. Did Greg really think he was the most difficult brat to ever present Nox with a challenge? How arrogant. "If you'd prefer that someone from the infirmary take the blood sample, that can be arranged. But I am entitled to it. You have broken multiple rules of this school, including hosting a party with alcohol that was open to minors. It's reasonable for me to assume that you may have partaken in illegal drugs as well. It's within my rights to have your blood tested for illegal drugs."
Nox stared Greg down. "Per the rules of this school, which were included in the materials you received upon your arrival, drug use is strictly prohibited." He quoted the rule word for word. "Suspicion of drug use can result in mandatory drug testing. If students are found to be using illegal drugs, they can be expelled. Now surrender your blood to me, or I will drag you to the infirmary to have someone there extract it. It makes no difference to me either way." The rule really did exist, but Nox's reasons for wanting a blood sample were a lie. However, he was very good at lying when necessary, and Greg wouldn't know the truth.
