Well, there was the type of mischief in which you 100% were going to get caught. Which wasn't always fun, but most of the time those instances were still worth it. And there was also the type of mischief in which someone else accidentally got hurt - which always sucked all of the fun out of an idea. But THIS idea there was like a 50/50 chance of success and the odds of someone getting hurt was really super minimal.

So.. yes. FUN mischief.

Vera certainly would have found the Ravenclaw's logic to be sound. Although, with Aurora being a Ravenclaw she also just would ASSUME the logic was sound without actually hearing what it was. So when she had picked two of the three victim components, there was no questions from the Gryffindor. She grinned at the younger girl when she giggled, giving the smallest shrug of her shoulders. "is it mean, or am I actually being considerate and shaking up their current monotony of studying?" She could easily come up with an argument that this was FOR the boys and not for her own purely selfish amusement. Did she believe any of it? Not a chance.

This would have been more prime of a prank for Valentine's day, and she made note of that for the next year if this worked, but in the mean time this would do for now. "That is exactly what I'm going to do!" Hopefully the boys wouldn't be docked points for their house because of their incorrect uniforms. Except... it was Slytherin and not her own house, so maybe it was fine if they did. Another thought perhaps for re-using later on Hufflepuff if that ended up being the outcome. As for what to do? Vera handed her own of the now bright red shirts while she grabbed a dress as well. Thankfully, the clothes were currently sitting in a bit of water now - soaking, she assumed. "Let's each add one of these first and try to stir it and see if we like the color. Or if we need deeper." She left Aurora briefly to begin that process, as she scoured the area for something to stir with. She spotted a broom and determined to just use the non-bristled side, rejoining the younger girl with her find in tow. "I wonder if Professors will try to use some type of magical forensics on this." She commented, glancing at the broom before deciding juuuust in case, perhaps she should be the only one who handled it.
