It had been quiet for a few minutes, so Mariel decided to work a bit more on her potion. As the water had been boiling, she started to drop the ingredients in and let out a startled shriek as a loud explosion rocked the classroom, causing her to scatter the scurvy-grass and instinctively throw her hands up over her ears. Potion was now sprayed everywhere, including her face and down the front of her robes. Slowly she put her hands down and vaguely wiped at her face as she watched the next events unfold.

Apparently Peeves hadn't actually gone away as he was still causing complete chaos. With the presence of yet another adult, she looked at both of them helplessly, wondering why they had not yet rid the classroom of the poltergeist. Certainly an adult could take control?

She soon started chuckling as the groundskeeper started singing. He looked most uncomfortable but she really couldn't help it, until she realized he was singing because of the potion. That's what it was supposed to do? she thought horrified. She was almost grateful for the disturbance Peeves caused in not being able to finish her potion, not wanting to unknowingly be subjected to randomly singing musicals.
