Leonidas: Captain, I leave you in charge.
Captain: But sire
Leonidas: Relax, old friend. If they assassinate me, all of Sparta goes to war. Pray they're that stupid. Pray......we're that lucky. Besides......there's no reason we can't be civil......is there?
Captain: None, sire.
Leonidas is leaving the Captain in charge of the 300. The Captain is nervous and Leonidas tells him why he shouldn't be.
