Despite being the one to come up with the theory<span style="font-style: italic">and</span>being the one who had just spent hours comparing the two signatures, Draco really had no good answer to Potter’s question. It was completely unheard for someone’s signature to change and while Draco was glad that he hadn’t put out the theory only to be proven wrong, it had mostly just left him with more questions.<br/>It was going to take a lot more work and a lot more research before Draco would have a proper answer as to what this meant,  or even how it had happened in the first place. He had never heard of magic that could alter someone else’s magical signature, nor could he see much purpose in doing so, other than simply ruining Potter’s day.<br/>It seemed like an awful lot of work for very little impact and it made no sense whatsoever to Draco.<br/>“I don’t know,” he stated, not much for admitting it, Potter having probably hoped that the reason he had come up with the theory was because he had some idea as to why or how someone would do that.<br/>“I have never seen something like this happen before.”
