Question: Were people able to "lock" the Holodeck doors so that others couldn't just walk in on them? I don't recall an episode where the doors were locked that wasn't because of some malfunction. It seems like Lieutenant Barclay, for example, would either lock the doors during his "fantasies" or have some "fail-safe" that shuts the program off when being walked in on. Otherwise, it's just a really dumb thing to do (for him or anyone playing out a fantasy) knowing they could easily be caught.
Question: Near the end when they are in the holodeck for the memorial ceremony for Lt. Yar, Dr. Crusher's uniform is green and seconds later it is blue. After watching it several times, it does not appear to be a trick of the light. What happened here? Why would she have on a green uniform in the first place?
Question: When the away team first beams down to the location where the shuttle has crash landed, the serial number on the separated nacelle is visible as 1701-D, as also seems to be inscribed on the shuttle itself. Shouldn't this serial number only appear on shuttles coming from the USS Enterprise?
Question: Posting this as a question, rather than a mistake, as there may be a logical explanation. After Captain Picard, Barklay, and Data become tracked in the simulation of the Enterprise, several times we see them separate to different parts of the ship (Data going to Engineering while Captain Picard remains on the bridge, etc.) Since they are physically in the holodeck, close to each other, they're being tricked by the holodeck. Why, then, when Data throws his comm badge toward the warp core (to prove they're in the holodeck) does the holodeck not continue "tricking" them? If the simulation can cope with two people visibly walking further apart than the actual room, why wouldn't it use similar techniques to make it appear Data's badge just landed where he threw it?
Question: How is Moriarty's simulation able to fool Data? Throughout the show Data is shown to have vastly superior senses to humans. Additionally, spatial tricks and forced perspective would be ineffective on him since he doesn't see the same way humans see. In another episode, Data is able to discern the incredibly slow movement of an object caught in time. It seems unlikely he would be unable to tell his surroundings were computer generated.
Question: The ever-popular gag in this episode is that Worf consumes prune juice for the first time and declares that it is a "warrior's drink," to Guinan's amusement. However, Worf was adopted as a child by human parents, he grew up on Earth, he was highly educated and graduated Star Fleet Academy on Earth. Given the reputation of prune juice as a natural laxative throughout human history, how could Worf not know what prune juice is, having lived most of his life on Earth?
Question: Whenever anyone wants to contact someone else from another part of the ship, they hit their badge and say (for example), "Picard to Engineering." In no episode ever is there an instance where we hear somebody call someone else who is not involved in the current scene. We should assume, therefore, that when communication like this is initiated, it is only heard by the recipient of the page. So the question is, how can the ship's communication system know ahead of time who the person is paging? In other words, if Picard says, "Picard to Engineering," what keeps sickbay from hearing his call? There can't be a time-delay (i.e., the computer does not make the page until it hears the entire page, and then directs it only to the intended recipient) because in many episodes we hear the reply right away. Can anyone explain this? Are we simply "lucky," in that we only hear pages made by or sent to people in the scene we're watching?
Question: I can't tell if this was a mistake or if there's an explanation. When the Borg are on the Enterprise's bridge, the first two are covered in the green light indicating they're being transported back to the Borg ship, but the 3rd one (the one successfully shot by Worf) has no lights, he just fades away. Why?
Question: When Scotty was at the door of the Holodeck, he calls for the bridge of the Enterprise, "no bloody A, B, C, or D." When the doors open, it's the bridge of the original ship. However, he was Chief Engineer on the refit Enterprise (no A). Besides the obvious "it's in the script", why didn't the computer ask for a distinction?
Question: When Riker and his father are doing anbo-jyutsu, what do the Japanese characters on the armor and around the ring say or mean? I read what the spoken Japanese lines meant (or at least why they attempted to say, I understand their pronunciation was bad), but couldn't find the writing.
Question: I get why counselor Troi would wear what may be considered civilian outfit or non-standard uniform, but why does she never wear her rank insignia for the first 5 or 6 seasons? In s5e5, "Disaster", it's revealed she has the rank of Lieutenant Commander and is in charge as the highest ranking officer on the bridge after the accident. Did I miss something, or was this just something the writers decided to add late into the series? In previous episodes, I never got the impression she was a bridge officer, or even had any Starfleet training, only on the bridge on the behest of Picard who wanted an Empath to help when encountering someone, or something, new. I never saw her take command in any situation (for example, Data whose rank was also Lieutenant Commander, was often seen taking command of the bridge for night duty or other reasons). Was there any previous episodes that mention her rank or training or shows her insignia, etc?
