Summary:	Internal Affairs Officer Sloan arrives on the station, announcing that there has been a possible security breach. He believes an officer may be passing information to the Dominion and promptly confines the senior staff to quarters. Later, Sloan summons Bashir for a brief interview, which appears to go well. Back in his room, however, the doctor learns that O'Brien was interrogated for two hours -- about him. Just then, Bashir is taken to a second meeting with Sloan.
