"True, but you saw her, and while you might not have gotten a great look at her, she could have thought you did. I mean, I have a hard time believing she's not going to kill someone just because they don't have a memory. Look at the ways she's killed the others, she clearly enjoys it. Even if there isn't a memory for her in the end." Hermione was more rambling now than anything, no longer looking at Ron, but more speaking as things entered her mind.
"I'm glad you feel that way, because I agree. The more all of us as a group know, the more we'll be able to figure out." The box peaked her interest. "Really?" she pushed a few things around on her coffee table before she found her note pad, covered and filled almost completely with scrawled notes on all the things she'd been looking into since this started, and wrote down the box and what Ron said about it and the memories. That would be good information to have once she got into the DoM. "It makes sense, really. I mean, only the people who are reliving those memories are carrying the mark of them. It's like a cancer, an invasion of the body, leaving a mark as proof. But the thing with cancer is it can be removed..." she trailed off before scribbling some more notes down.
"There has to be another way to get rid of those memories without killing a person. What if we could simulate death, like one of those living death potions, so the person appears to be dead, physically. Perhaps whatever it is that triggers the memory to release from the person will be triggered in something like that. If we can free those memories before she can, then we may be able to destroy them in the process. If they're so important to her, they must mean power, why else would she risk so much and go to such trouble." Hermione looked up at Ron, hoping she didn't sound completely mental at this point, talking about simulating death like symptoms on the people who had these nightmares. Of course, if she had them, she'd be working out an experiment already to try, but alas, it wouldn't be that easy.
