Gilgamesh(archer) voice dialogue in Final Babylonia different?

*SPOILER ALERT*

If you already beat Babylonia, in the last chapter, Gilgamesh will become his old self, the stroger archer version instead of his Caster-class.

If you use him (the NPC Support) in the final battle against Tiamat, do you notice there are lots of differences in his dialogue/voice compared to normal Gilgamesh servant? From my observation, the NPC Support has different dialogue compared to the same Gilgamesh but as your servant. I just wonder what is he saying. I can't find it anywhere, most website only post his dialogue as normal servant

Sorry for bad english
