So I'm a teeny bit concerned about the Mirror Discovery having almost certainly been transposed with Discovery-Prime. Given how successful Mirror-Kirk and company were at being incognito when the same thing happened (dammit, will happen) to them, there's probably some trouble brewing back in the ol' normal universe.
Production-design wise, the new Terran Empire logos are clever but, you know, too clever. The sword replaced with an upside-down delta. The mirrored Earth is a step too far. Is mirror-Earth actually backwards from our Earth in terms of the continents? That's wacky.
Also, I'm pretty sure this the first time a character on-screen has actually said the word "mirror" in reference to anything from the mirror universe.
I know some folks aren't gung-ho on that particular storyline, but I'm curious to see whether or not Ash is going to fight who he truly is, or accept it and revert back to his old self. Right now, he's horrified, but that could change. Then there's his murder of Culber, which was crazy. I honestly have no idea where it's going to go.
The way he keeps spacing out, combined with the Manchurian Candidate shout-out, makes me think that Tyler qua Tyler probably doesn't even remember killing Culber. Fat lot of difference that makes.
Anyway, now we know how things are going to end for him; Burnham makes a set of Klingon Icons, all of which are Kahless, and tries to override his Klingon programming with new instructions that way.
I’d rather they not, it would stick out.
We saw Shenzhou and Discovery side-by-side in this episode, and they were nearly as different from each other as a faithful TOS ship would be from either of them in terms of coloration and hull styling, and it didn't seem that odd. Never mind all the mismatched Starfleet ships we saw in the TNG-era. Excelsiors, Mirandas, Galaxies, and Akiras hardly seem to go together until you see them next to each other every week.
One of the pilots in the Klingon Raider was an andorian, is there a good shot of it?
Nope, but in the preview, we saw an Andorian from behind in the group shot of people walking towards a building outdoors (white hair and an antenna peaking up), so it seems pretty certain we'll probably see one's face before too long.
