He compliments Galeno's impulsive and idealist nature but rather subtly. xD You won't see him saying 'good job' that much :P He's pretty reserved yes, but with good reasons. You haven't seen him in 'killmode' though...that's when he gets bloodthirsty and reckless. Only in fights though so don't worry xD
I also see Galeno as quite an intelligent individual, being able to communicate with Zeph so well like that. However, I can also see the potential of the Ampharos getting slightly hyped or excited, something Zeph normally doesn't feel.
How's my writing compared to normal people there?
