James, having recognized the witch as someone on his "immediately run from" list, had made his way to her location. Deciding he should act like the instructor he was, he stopped Neku from his charge by yanking him by the sleeve by his clothes. "Idiot." he hissed. "You're nowhere near her level. Don't go getting yourself killed." 

Stepping in front of Neku, James put on a diplomatic smile, although he had no idea whether it would work at all or whether she was just going to whack him aside. 

"Hello, Ms. Schweinborg - or would you prefer I called you Erika? I'm James Heinson, and although we may have crossed paths before I don't believe I've ever had the pleasure of talking to you in person."

He stopped there, wanting to see if the powerful witch who outclassed him by so far - he considered her one of the most powerful beings he had ever known simply because he had never been able to comprehend her powers - would respond positively, preferably by telling him which of the two choices she wanted him to call her by, and, more importantly, if she recognized him as a witch from the assembly.
