Neither do I, and this isn't the first time tension has started over a trivial matter. This is an RP, and as much as we'd all like for it to stick to the canon as close as possible, don't be so anal about every single thing. It just starts getting annoying and really takes the fun out of an RP we should all be enjoying. Samantha wants to punch some kids in the face? Oh no! It's going to completely ruin the continuity of Rowling's works! New spells are being made? Can't have that, it isn't canon!

See how ridiculous that all sounds? Try to be more lenient on these things guys, none of it is going to mess up what's already been established in the series.
