For the first time since the cups had caught Sisse's attention she glanced around for the matrons. There weren't any in sight. Odd. "I'm not sure." She admitted, her mind spinning as she tried to think of another plan. She cast a freezing charm on a teacup going by, grateful when it stopped moving. "Can you get the left side, I'll get the right." Perhaps if they could divide the room they might manage this alright until a matron arrived. "There's a door to the library over there." Sisse nodded toward the left wall before casting another spell. "Maybe we should check in there." They could freeze the cups on their way. Or Millie could just try on her own. Sisse honestly wasn't sure what was the best choice at this point.
