And of course, instead of anything remotely straightforwards we get another required password. I'm starting to think this game is getting too big for its own good. I do have an alternate idea how to narrow this down, though...

First off, Philter is a girl. This is 100% true. I doubt Philter is playing crossdresser by disguising themselves as Nairek. It would be extremely unlikely, though possible. Second off, Philter has some Green Thumb abilities but may not be a Grass-type. I, personally, do not believe that any of what we have found totally neutralizes another Grass type. Third, whoever it is must have severe frustration about their current position in multiple ways, mostly manifesting as precieved uselessness to a crippling degree. We've already met someone fitting all of those: The Garbador who mourned Krum's death, who's name I forget. She is a seriously big target, one of our primary suspects actually.

We need to ask Elton the Grotle about the Wing Cuffs, and we need to ask Mac the Glameow about the information we've gathered on Philter for a psychological profile: After all, he deals in Criminal Justice and should have probably been one of the people we asked from the beginning like Pormalu. I'm sure that he may be able to help us narrow down suspects more narrowly.

EDIT: OK, so, on the one hand, that's really unfortunate. I'm going to presume it won't make us outright miss things on the search, unless Neo has been hiding stuff from us in regards to Sanity (and to be perfectly frank, I think he's tried to make abundantly clear as possible whenever this kind of thing starts sucking). Lita won't hit 0 Sanity (and indeed this is probably one of the few times she'll take SAN damage period as that perk basically makes her otherwise immune) so I guess that's OK, but...
