Balthier's relationship with Naja so far is mostly business-centered. He was a little annoyed with what he had to go through on Destiny Islands, but even if he does get shorted on the gil front, the discovery was almost worth it. Almost. He honestly isn't really very annoyed with her stinginess as he's no doubt encountered it many times before from different people. He is, however, interested as to just where she happens to be going with her searches for information.

In regards to Hades, Auron is honestly... confused. XD He's still very Not Amused considering everything he's done, but he has no idea why Hades decided to do all that, how he knows him, and what exactly Hades's problem is with him. So yeah, he's more "I have no idea why you're doing this" than angry with him. XDD Beyond that, he knows Hades is a threat and is going to try and keep a careful eye on him, especially considering the events of the party.

Braska... I don't think he hates Hades, but he definitely does not like him. He doesn't really understand how Hades could do those things to hurt other people, but he has no intentions of allowing Hades to do harm to anyone else. If he figures out that Hades is planning on doing something, he'll probably be one of the first people to sign up to stop him.

Kefka... If Hades were money, Kefka'd be seeing dollar signs. He's got a god right there in front of him who basically just asked Kefka to impress him, and while he doesn't know exactly what Hades can offer him, he knows an opportunity when he sees one. If he gets the chance, he's definitely going to be doing some sucking up. XD
