"He didn't hurt you?" he asked. "Allison, he cursed you. It may not seem bad now, but when you get cursed by Voldemort you usually end up dead at the end of it. Now I'm praying that neither you nor my son or his friends will die, but you should be aware of the fact that he did indeed hurt you."
He ran his hand through his hair, trying to think of a way to explain it. "It's like a virus," he said, looking up at you. "This is as real as if he injected you with a virus for which there is no cure. Something unlike anything that any doctors have ever seen. These are just the first symptoms. Things will get worse, so yes, he did hurt you, and I'm trying to prevent that he's doing it again."
He sighed. "I didn't say it was your fault, nor do I think it is. I know whose fault it is. It's not yours or James, it's Voldemorts and if anything mine. My son would not be targeted if it was not for me, you would not have been targeted if it was not for me. But in the end it's Voldemort who acts, and it's his fault. But as a mother, can you blame me for wanting to protect my son the best I can? And call me Harry, Mr Potter is for people I work with or dislike."
"James told me you want to be tracked, and I have already made arrangements for that. With your permission I intend to put several different tracking spells on you before I leave. Wherever Voldemort might take you, we'll know."
He reached inside his robe and pulled out a small package, which when opened revealed a small silver bracelet. "This is a portkey," he explained, handing it to her. "I think James told you about what they do. If Voldemort comes to your room again, all you need to do is say a certain word, and it will deliver you want. All that is required is that you tell me where you want it to take you, and for you to tell me which word you want it to react to. It should be one you'd remember, but never use accidentally."
