Note that Q and Q are not the same person.

Fun fact - the actress under that makeup also went on to play the Female Changeling.

The Prime Directive shouldn't have even applied with that. They can't stop a foreign government from executing their own citizens for stupid things, but trying to execute another nation's citizens is an international incident and falls under standard international politics. The Federation seems to give Starfleet ship captains ambassadorial powers, so Picard should have started threatening sanctions and making comments about how executing Wes could be considered an act of war.

Ro was basically on probation in her first appearance or two, IIRC. Uniform modifications are allowed at the discretion of the officer's CO, and Ro was already in something of a disciplinary thing, so forbidding modifications makes some sense.

While the earring is typically religious and she may have been able to argue for reasonable accomodation on those grounds, Ro specifically wears it on the left ear, which is considered a secular way to show familial heritage while also indicating you don't follow the Bajoran faith.

They couldn't get Chao or Meaney quite as frequently as everyone else because of their film careers. I know with Meaney they really wanted to show off his acting skills when they had him and determined that he portrayed suffering really well, so O'Brien suffered a lot. I think Keiko's problem was that she was only in a couple episodes per season and the focus was typically on whatever horror was happening to Miles that week. She's not so much a bad wife as a barely present side character.

Unfortunately, the writers often forget this. VOY waffles a lot on whether or not Tuvok is literally emotionless.

I've heard that Data was originally going to be a science officer and the blue uniform didn't work with his makeup, but I don't know whether or not it was true.

I think the police state was their solution to infighting in much the same way that Surak's faction took up a quasi-religious adherence to logic.

I love Gowron's 'is this really happening?' face throughout the episode.

Vader only starts sensing Luke after he gets some training and goes from being merely Force sensitive to a proper Force adept. Trained adepts are consistently shown in the franchise to be easier to sense than untrained sensitives, like Leia.

Vader only knows Luke is his son after being told his name. He only finds out Luke has a sister after ripping the knowledge from his mind, and it's unclear if he got her name.

Interestingly, this is actually a thing on the show. In one TNG episode they figure out how to open a small window in their own shields to beam through. It becomes standard procedure in TNG, DS9, and VOY after that. Presumably, you can exploit an enemy ship attempting that.

As much as I enjoy seeing the asshole Vulcans be taken down a peg, I really want to see more of her husband. He was laid back and expressive, so I thought there was going to be a twist with him. I hope he comes back later. He may be one of those Vulcans that gets the whole, "logic is the beginning of wisdom, not the end," thing.
