Maybe through Nate's work. He was researching them, after all. Plus, that wouldn't necessarily make Nate a bad guy. I'm thinking of a sort of deal, where Nate supplies Prometheus with information in exchange for Prometheus telling him Green Arrow's identity, and becoming a member of the Legends in the process.
