Everything Isabelle was trying just wouldn't work. The common room flatly refused to open for her, and quite frankly it was now beginning to get on her nerves.

Along with the sharp chatter coming from Prefect Lecium and one of the two Slytherin girls present. "All right, that is enough," Issy said, moving away from the barrel and turning to face both girls. She'd overheard the whole conversation and to say she wasn't particularly taken in by the Snakes mock upset was an understatement. "If you two can't behave in a civil manner while I try and sort this problem out, I suggest you separate and you return to your own common room, Miss Logan." Isabelle gave her a look, and Belle too. She wasn't in the mood to be dealing with arguing teenagers.

Now, to handle the ideas Minerva and Laura had come up with. Peeves and a chainsaw. One had some merit, the other not so much. Sighing, Issy crossed her arms and began tapping her wand again. "Peeves is a poltergeist, he's more than capable of throwing things around, and quite possibly locking the common rooms. And I suspect it's all of them," she said, looking over at Minerva. "But... so many people at once? I just don't know."

As for the chainsaw. "Laura, come here a second and feel the force on the barrel," Isabelle said, bending back down to touch it, and gesturing for the girl to do the same. It was like a forcefield, one that was bouncing every spell off it. "If we try and use a muggle implement to get through that I hate to think what would happen. Especially with one so dangerous as a chainsaw. Although you're right that it would destroy the barrel, if this magic wasn't protecting it."

Nothing was working. Sooner or later she'd have to think about finding them all somewhere to stay.
