For a brief moment, just long enough for the class to be taught, Ellie had forgotten about Woopy. She had gotten lost in her teachings, as she loved to do, and all else had faded away. They were talking about the hardening charm, one that could turn plants into a substance almost as hard as stone. It was a particular favorite of hers and she grew very enthusiastic about it, demonstrating time and time again, correcting each student's attempts individually instead of calling them out and telling them what they were doing wrong in front of the class. She felt it was rather humiliating and since she had been taught that way, she had vowed when she started at Hogwarts not to do that to her own students.

But as the last student filed out, Woopy appeared right in front of her. Since he wasn't clinging to her--yet-- she was slightly more inclined to not want to shove him out of her room and lock the door. Not that it would matter, since house elves were the only creatures in the castle that could apparate in the vicinity but it would give her peace of mind for a few moments.

"Really, Woopy?" she sighed, "What did I teach you?"
