• The Romulans are aboard the station to be debriefed on Dominion intelligence, per the agreement to use the cloaking device on the U.S.S. Defiant (see "The Search, Part I").
  
• The Klingons are aboard the station waiting for their ship to be overhauled.
  
• Technobabble explanation for O'Brien's time jumping: A quantum singularity orbiting the station is pulling at the radio-isotopes absorbed by the Chief in the accident. Mm-hmm. The quantum singularity is actually a cloaked Romulan Warbird's engine core (see the TNG episode "Timescape").
  
• The future O'Brien returns to the past when the present O'Brien dies of radiation poisoning.
  
• Jack Shearer went on to play Admiral Hayes in both Star Trek: First Contact and the 4th season Voyager episode "Hope and Fear".
  
• Chief O'Brien has Quark install a dart board in his bar. (Dr. Bashir proceeds to beat O'Brien 10 games in a row.) The dart board will get a lot of use throughout the rest of the series.
