In the opening pre-titles scene in the torpedo room, Data and the Lieutenant replace the access covers on the converted torpedo and there is an object resting on top of the casing. As they turn away and the camera view changes, the object has disappeared.
When Data and Lieutenant D'Sora are drinking the toast, both their grips on their glasses change between camera angles.
Data seems to break his contraction rule a few times in the episode, when he says "Honey, I'm home!" and "You're not my mother!" It is conceivable, though, that Data has drawn those phrases from his cultural and literary sources and integrated them into his program for romantic relationships. This becomes evident particularly when he explains the line "You are not my mother" (without the contraction!) as the appropriate response in the given situation.
Worf describes Lt. D'Sora as serving under his command. However, D'Sora is never seen performing security duties; all of her on-duty scenes have her performing as an engineer, which would make her part of La Forge's staff, not Worf's.
This is incorrect as at the 36 minute mark, Lt. D'Sora, is seen manning the Tactical Station on the bridge. Security/Tactical are in control of the ships weapons and weapon systems and would be the ones to work on the photon torpedos.
When La Forge and his two engineers set out to investigate the damage between decks, Lt. Van Mayter breaks off from the trio and heads off along an intersecting corridor, where she is immediately swallowed by the deck (off camera). La Forge and Thorne then run back when they hear her scream, and they find her embedded into the deck plate, facing them. Since she had been walking away from that intersection, La Forge and Thorne should have seen her from behind, not the front.
When Data and Lt. D'Sora are touching each other's glass, it makes a ringing sound. However, in that instance (= camera angle), they are both holding their glasses at the bowl rather than at the stem. A glass held that way would not be able to make that typical ringing sound at all, at best, a dulled version of it.
Referring to the mess in Jenna's quarters, Data describes her to apparently "have an *adversion* to orderliness". He obviously meant to say "aversion".
When Jenna asks Data about his reaction to her mess, he replies "I believe I observed that..." Data is capable of memorizing every detail and every spoken word, so he should know exactly what his response had been. The term "I believe" in this context is therefore rather atypical for Data.
