Being a Gothic creature of the night, this kind of lesson did not bother Kitty at all. She was by a nature a night owl - which meant it took a long time for her to fall asleep sometimes and often she would get up for a walk around the Ravenclaw dormitories. So she was wide awake and attentive as she entered the classroom, wondering what they would study.

"Goodnight Professor," she greeted Kalen cheerfully, eyes focusing first on him and then on the door. "I love how we're having this lesson at midnight. Is that a moon door?"

A door that only opened at midnight, that is.
