Connor decided to journey with Oliver, and created a costume similar to his. Connor served as Oliver's sidekick, also meeting with Eddie Fyers, the former federal agent that acted as a form of counsel for Oliver. It was during this time that Oliver learned about his connection to Connor from the ghost of Hal Jordan: Connor was Oliver's son, conceived during Oliver's college years, a truth that Eddie Fyers had already deduced, but whose revelation Oliver did not take well.
