When Starbuck's viper appears before Lee at the end of "Crossroads, pt. 2", the name panels on the sides of her ship are missing. At the beginning of this episode, when no time has elapsed between scenes, the panels are seen on her ship.
When Starbuck's ship is being inspected, the tail number changes from 8757NC (when Chief Tyrol is speaking to Admiral Adama) to 4276NC (2nd shot of Apollo standing on ladder).
When Tyrol is explaining the oddities with Starbuck's viper to Roslin, Adama, and Lee, Mary McDonnell is wearing her wedding ring (which is normally removed, since Laura is not married).
When Starbuck is telling the Admiral, the President, Apollo and Tory what happened during and after the event at the maelstrom, she states that she passed out and after coming to she found herself in orbit of a planet, whose "yellow moon and star, matches the description in Pithia", as opposed to the 'yellow star and moon...'.
