Hunk just sighs- he doesn't know anything about mythologies! Or Summoner. Or Eidolons. He knows it's probably important but part of him just doesn't care because, well...

"Maybe the octopus is friendly, or Shiva's really chatty, or- Wait, what if Eidolons can't talk?" And then his eyes go wide. See, that'd make it harder to get answers. And he already had nothing but second-hand knowledge to contribute, as much as he wanted to do more.

"Do we know any Summoners?" Then he frowns, if only because he has no idea.
