Professor Vindictus must have been at near starvation. "Okay, okay...I...umm...the only other piece I have on me, though, is my half-eaten piece," she continued, showing it to him. Anna's eyes drifted away from her flying professor when Professor Bunbury, who appeared extremely hyper, strolled up in search of the niffler. These professors were just...odd. "Can we discuss this cake as we walk to the Mirror of Erised, though?" She looked towards Professors Bunbury and Forrester, wondering if they'd agree to go along, as well.
