The tall student smiled back at his headmistress and nodded his head slightly, confirming what she just said as well as excusing himself - he had to think about this class, and what it would truly be like - he hadn't heard exact and detailed stories, but from what he picked up around the academy it was not only harsh, but outright deadly in parts. Best to come up with a plan for that class now rather than later. "I always have to work hard, Third. And i'll try my best... I always have to do that, too, after all. Now, I hope to see you later. Headmistress, miss... friend." He nodded his head towards the two of his superiors again, and then towards the other student who was still standing around, likely in awe at the undead's imposing aura, and walked off in a slow stroll. If nothing else, he could at least savour the bit of time he had before classes began.
