A Romulan delegation arrives to study reports on the Dominion, a privilege granted in exchange for the use of a cloaking device aboard the Defiant. Meanwhile, O'Brien, at Quark's riding out a mild case of radiation poisoning from an accident, is suddenly transported to another part of the bar, where he sees himself having a conversation with Quark. He just as suddenly returns to where he was, then falls over in pain. Bashir blames the radiation and assures O'Brien that hallucinations are a normal side effect. But when O'Brien returns to the bar five hours later, he has the same conversation with Quark that he 'hallucinated'. Dax theorizes that O'Brien's exposure to radiation could have caused him to temporarily shift five hours forward in time. Then, O'Brien experiences another timeshift -- into the middle of a brawl in Quark's between the Romulans and some Klingons.
