Witnessing just how quickly Leo had gotten used to the second stage Qi, Quinn started to emphasise how other vampires must feel when comparing themselves to him.
"Don't feel so down." Leo encouraged him. "I've felt the kind of aura you've demonstrated all the time in the dojo. Because of my ability, I have always been able to sense Qi on a different level compared to others. As for control, my unique soul weapon allows me to fine tune not just mine but the Qi of others as well. So as long as I have seen and understand how it works, it's an easy feat to replicate it. If it had been anything else but Qi, it would take me a while to learn it as well."
Quinn believed he had hidden his jealousy well, but he realised too late that it had just been him hiding the emotions on his face. Which was useless in front of the blind Leo who saw beyond a person's face.
