Public humiliation or private? Combination of both? Hmm, some ideas were forming, but most of them didn't require objects to bring with him, so he only grabbed a couple things. Breaking curses had introduced him to some new ones beyond what they learned in class. He'd looked up loads after he broke them. Admittedly, many of those he hadn't ever cast before, but he knew the theory.
But first on mind was dealing with however Draco hexed his door. That mattered most. After having successfully getting into Rosier's wardrobe, Zach was feeling a bit more confident in his skills. That had been a major test. This one was also a test, a different sort of thing than much he worked with. But really, curses and wards were curses and wards.
Blaise was already there, and Zach hadn't seen anyone else around. Pulling out his wand, he gave Blaise a smile. "Hello, I'm just going to get to work," he explained. It was better not to distract him in the middle, but he assumed Blaise had common sense.
Then he began casting, very careful at first, just figuring out what was there before actually breaking it. He wanted to know it all and remove it one hex at a time.
