do snape apologists think snape used sectumsempra for hedge-trimming or hair-cutting or what
actually I have heard 100% srs Snapewives or whatever saying he probably invented it to cut potions ingredients. never mind the fact that potions ingredients need to be cut precisely in many recipes and sectumsempra just kind of slices at whatever it hits, and Snape would never just hack away at his potions ingredients.
also the fact that it says FOR ENEMIES. what are your enemies, billywig stings??? come on now. COME ON NOW.
