[Her search is indeed for a metaphysical 'heart', and find it she does. Naminé's not quite sure whether or not that's a good thing; will this wear off, or will Rei be trapped like this until-- well, it's not a nice thing to think about. Naminé can indeed tell the difference, although it does not come as the surprise it might have if she hadn't already spent some time with the other girl. As it is, it doesn't much change Naminé's opinion of her.]

[The girl hesitates, thinking over the options at hand again, then,] I've been trying to learn new-- techniques. [Or magic, rather.] I don't know if any of them will help, but-- I'm going to try. ... Whatever happens, I'm sorry. [She's just not sure if there's anything that can be done or if what can be done will cause more problems than it fixes, but - still keeping her distance as much as possible, she sets about casting what few status-ailment relieving spells she can think of and actually manage to complete. Those are ones she's never had much opportunity to practice, and so they are obviously the work of a novice, but... she can't bring herself to just leave Rei there without at least trying.]
