Spies? Cool, never thought I'd warrant spies. What are you supposed to do with spies, lock 'em in a dungeon and leave them alone until they escape? I don't remember any spies in Spartacus, just slaves and Romans and stuff.

[Lucius Cornelius Sulla]

Spies would be low-born. They would be given the same treatment as the rebel slaves.
