Two episodes earlier in Melora (1993), Julian says that Anti-Gravs don't work with the Cardassian construction, yet here, he calls for and then transports Quark on one.
During the flashback scene where Odo first talks to Kira, she calls Odo "constable", but the term was supposedly not known by Odo (as it's an old Earth term) when Sisko 1st met him in season 1, several years after the flashback.
When Quark is shot, he is thrown back several feet by the blast, but the shooter doesn't have any recoil reaction.
In one of the flashback scenes, Odo says something occurred at "2500 hours." Earth time only goes up to 2400 and nothing in the series up to this point indicated more than a 24-hour day. Correction: One day on Bajor is 26 hours and this is a Bajoran station. There are numerous references to a 26-hour day in this series.
When Quark is attacked at the start, he flies backward and is visibly lifted up slightly by the line pulling him.
When Rom and Odo arrive at the store that Quark and Rom stole the box from, Rom tells Odo that the box had been hidden years ago when the "ship's" store had been the chemists shop.
They are not on a ship they are on a space station.
They are not on a ship they are on a space station.
Quark tells Rom to 'Go get me an imager. Go.' The second time we hear 'Go', Quark's lips say something else.
