Around Stardate 47569, Ensign DeCurtis was put in charge, by Commander Sisko directly, of checking the security measures surrounding the Paradan peace talks, when it was suspected that O'Brien had been replaced with a replicant Miles O'Brien. He was ordered to work without informing the replicant O'Brien, which elicited a rebuke from him, since O'Brien had discussed the security measures with the Paradans. Later, he worked on the security of the quarters assigned to the Paradans when the replicant O'Brien went to check on him. DeCurtis lied about being able to show him the measures he took in order to keep O'Brien out. He went to check on the replicant when he was working in Ops, making sure he was working on the busy work Sisko gave him to keep him from being directly involved with the peace talks.
