Retracing your steps is probably the best option at this point, yeah. [Martha's not sure how long that's going to take, though, if Aerith wanders around a lot. She seems like the sort of person who goes all over.]

And you're not crazy. Even if it might feel that way, you're not. [Martha smiles at Aerith, because she realizes that she hadn't really meant that to begin with -- but she can sympathize. When you feel like you just had something and it's nowhere to be found, it's maddening.]

It's no problem at all. I hope that you find it soon.
