Before I go to the next part
of the walkthrough, though, I want to leave you with what Gau would say had you
brought an actual solo-Gau party to Ramuh, as it's one of the bits of dialogue
that never ceases to amuse me in its brilliance:

TERRA...she ok?
Espers...from other world?
Why hide fact you Esper?
GAU hear fairy tale. People...Esper once live together peacefully...
MagiTek Research Facility...? There...your people?
R.a.m.u.h...You leave...?
Awoooo...!

Note that this guy, later in the game, has trouble saying 'yes'.
