I have a question about the post: I am not sure Billy's appropriate reaction to a person who can not only perform the complex magic to stop their torso getting halfway turned into a unicorn, but also reacted fast enough to a probably unexpected piece of technology with enough foresight to cast three transfigurations on small targets that will only be in flight for ~.01 seconds.
Is this a normal feat to be able to perform? If so, wouldn't Blackwell know that and not chastise Billy, and if not, how out of the ordinary is it, is it enough for Billy to be surprised/shocked/mystified? Would Billy also be shocked, depending on the answer to the previous question, that a person with such [potentially] prodigious reaction times did not transform Blackwell into a Blackwell-sized pile of cheese or something? Could my character perform such impressive feats? Also, can transfiguration rob things of their speed?
Also, I know there is no way for me to change Billy's or actions to reflect an understanding that this result may happen, but I could use some help figuring out an explanation for his frankly stunning ignorance [assuming his opponent's reaction is normal]. Maybe American isolationism? I could change his history slightly so that he has never actually fought in a battle or training exercise, or find some explanation like 'soviet soliders cannot cast transfigurations'.
