Corypheus is, at least partly, using slaves to support his occupation. The idea may be taken. [ he knows, at least, that the assassin that attacked the Archon was a slave, and working with the Venatori. If the woman's smart, she'd call on the rest of those in her station to join, and if it means more freedom than they had before, they won't care who it supports. ]

You'd need information - how many of the slave class are allied with Corypheus, what he's offering them, what he's asking from them in return, what we can give instead. We cannot go in with an army and expect to win them. With slaves, when one group is freed, all others are made to suffer. It must be all at once, or none at all.

[ that, and: And they'll want the Archon's head. he'd like to tell her they could win some over just in killing him and making a statement to those slaves, but they were told to keep quiet, so he's keeping quiet.]
