Iolaus: (on Nebula's ship) Listen, if this thing works out, we're going to have to evacute a lot of men off that island. Would you..?
Nebula: Sure. Sure. But you'll owe me one.
Iolaus: What are you gonna do? Place me in servitude? Hold me in bondage for how long?!
Nebula: We'll negotiate. But don't sweat it. Bondage gets a bad rap!
Nebula: (finding the tunnel ending in a stone wall) I don't understand. It wasn't like this before.

Nebula: (looking at the new hole in the wall) No. Bigger.
Hercules: They always want bigger.
Disclaimer: Any resemblance between King Iphicles, Hercules' half-brother, and Ares, God of War, Hercules' other half-brother, is totally unavoidable.
