[Noctis' nice phone goes right in Eichi's pocket as well, as if he's forgotten. He's busy moving to peek behind other trees and glance at the ground. He doesn't actually put much effort into this at all. He's not the one who does things like this... Normally Wataru or Yuzuru will be there to help him out with it, instead.

Eventually, he glances over to Noct like he's wondering why he's not doing more.]

I appeared about here, didn't I? I was thinking that perhaps there might be some sort of clue, or something like that. You know, like a detective film, or a crime novel. [He's comparing this to a crime, yes.]

Honestly, it's just that I can't think of anything else to do, and keeping myself active like this eases my mind a bit.
