[It's good that he isn't instantly jumping to the conclusion that she could have altered memories. She might do that if necessary - but would prefer not to. These days there aren't so many reasons to have to alter the memory of a human as there were twenty years ago. Seeing as how doing so to all of these people is pointless to Ai, she obviously doesn't find it amusing.
Ai does frown a little bit at that.]
Yes, it appears they certainly are. So I'm attempting to ascertain whether or not it has anything to do with the maintainence they are performing on the dimensional stablizer.
[She motions to all of the books before her.
At that question, Ai does hesitate just a little.]
There are physical changes as well. [Ai does a very good job at not letting her gaze flicker down to his neck - now clean without the large tattoo that had once been there.] This I'm fairly certain they've done where necessary.
Since I've arrived I've kept a journal. I looked it over this morning when I noticed something was wrong. It matches up with what I remember. So if it is to be believed - then there are some who have suddenly become vampires where they once were not. [Or vice-versa in Zero's case but she doesn't say that.] Or my journal has been changed which is proof enough that they can manipulate something physical to go along with the different memories.
[Ah well, that answers Ai's question. So for the duration of this event, she will just have to make sure to call him by that name.]
Good, I would hate for him to have been on his own all this time.
