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.
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.
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.
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.
When LaForge 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). LaForge 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, LaForge and Thorne should have seen her from behind, not the front.
