Throughout the episode, the door to Captain Tobin's cabin alternates from having a lockset and deadbolt on the left side of the door to having a lockset only on the right side. And this was apparently the only passenger cabin on the ship ever to have a deadbolt.
When Captain Tobin boards the ship in uniform, the name plate on her uniform reads "CAPTAIN TOBIN". But name plates on military uniforms only show the serviceman's last name; the serviceman's rank insignia is found elsewhere on the uniform.
Cpt Tobin is shown wearing the NDSM and Good Conduct medals. Since the Good Conduct is higher than the NDSM - they should be reversed. However, as a Cpt, she would not be authorized the Good Conduct - as that medal is not issued to Officers. (note: NDSM = National Defense Service Medal)
