My favourite is when Hades talked to Hercules and Sora, and he said:
"You have a very important match today. If you don't stick around, who knows what kind of "accidents" might happen. Then Sora said: "Yeah! Accidents you cause! Hades: "Details. Who needs them?"
I also like the scene where Hercules says, that Hades is a sore loser and he is like: "Can't all be heroes."
