[He frowns slightly at that--he may not be particularly fond of being in this place, but the idea of forgetting the people you meet and things said or done here seems a little sad.]

Perhaps, but thinking about things that way has a bit of a pessimistic taste to it, don't you think? [After a moment though, he smiles again.] But I'm sure that even if you did somehow forget about it, you'll surely find out about them someday nonetheless--after all, Ash is not from Unova, but he found his way there after hearing about it elsewhere. [At least, that's the best example he can think of that's a little more optimistic than "What's the point, I'll forget anyway"] Either way, I do believe that someday you'll become a great "Ditto master", if not already one of the best. [Or even the best, because you're the only Ditto master we know of. ^^;;]
