"C-Calm down," stuttered the boy, making Arya realize that he had just been shouting a few seconds ago.
"I just thought that since the Minister had purple hair as well, you might be a dea- I mean dark mage," the boy continued, after Arya's facial expression showed that he had calmed down a bit.
During Arya's short encounter with the Minister he hadn't had the chance to look at his hair, what with him being pulled into some sort of dark dimension and all. But even then, back when he had first arrived, Arya hadn't spotted any wisps of purple in his hair. But since the brat was claiming that he saw it, and there was low chance of him making something like this up for no reason, it was something to think about. However, Arya decided to put it away for now and ask Cassandra about it when they got back, well if they ever got to go back anyway.
