Did You Know?


Captain Lorca's ship in the opening of the episode is the ISS Buran (NCC-1422) The Buran is a Cardenas-class starship in use during the 2250's by the Federation. The USS Yeager participated in Battle of the Binary Stars with the Klingons in 2256. Star Trek: Discovery: Battle at the Binary Stars (2017)

Like the contemporaneous Nimitz-class and the later 23rd century Constellation-class, as well as the 24th century Cheyenne- and Prometheus-classes, this type was noted for being one of the small number of Federation classes that had more than two nacelles. Episodes where these ships are used include; (Star Trek: The Next Generation: The Battle (1987), Star Trek: The Next Generation: The Best of Both Worlds (1990), Star Trek: The Next Generation: The Best of Both Worlds: Part II (1990) and Star Trek: Voyager: Message in a Bottle (1998)).

When Lorca swings the sword at Georgiou after pulling the knife from his shoulder and throwing it, you can see Michael fighting a woman in the background. She throws a punch at the woman that misses her by at least a foot. See more »


Captain Gabriel Lorca: I was just thinking about everyone who's ever said that victory felt empty when it was attained. What a bunch of idiots they were.

Mirror Lorca vs Mirror Kirk
1 February 2018 | by XweAponXSee all my reviews

I'm tired of the comparisons to Oroville, Oroville is not Trek, amusing as it is. It's not even similar to TNG, DS9 and Voyager. It's a parallel universe that's not being discussed in Trek at the moment. When Discovery runs into the Oroville or characters from it, let me know. Meanwhile, let Discovery be about Discovery.

"It's harder for an Uncivilized Man to pretend to be Civilized, than it is for a Civilized man to pretend to be uncivilized." - Mr. Spock, "Mirror Mirror"

But when that uncivilized man is Lorca, we find that what is difficult is not impossible, Mirror Lorca finds himself in the Prime 'Verse, and was able to take command of one of two experimental Discovery class ships, and even manipulate Stametz to find ways back to the Mirror 'Verse. When Admiral Cornwell started seeing through it, she was talked into taking over Sarek's dangerous mission, which put her out of the picture. She was Mirror Lorca's biggest threat.

We can go back and watch the previous episodes, and see that something was off with Lorca from the start. It all seemed so logical, but everything Mirror Lorca did, foreshadowed what was to come.

Georgiou, a merciless Emperor facing deposition, although not like Prime Georgiou, is still a competent commander knows her ship, is integrated into it. As vicious as she is, she still has feelings for Michael, which may or may not make her Manipulate-able.

Mirror Stametz work was a perversion of the Spore drive, and is destroying the whole network. Is there a solution to this, which will open a door back to Prime Verse, that won't blow up discovery?

For this to happen, Michael has to work on Mirror Lorca and Georgiou, a three-way conspiracy. And Michael makes a tacit commitment to keep Mirror Georgiou alive.

The Character who wins Most Improved award is Saru, who has become a more than adequate Captain. And this also pushes actor and stuntee Doug Jones into a starring role. I'm very impressed, from Abe Sapien to Saru. Doug has been a multitude of weirdly designed angels and daemons in several Guillermo del Toro films. My favorite being the Angel who saves Hellboy in "Hellboy 2 The Golden Army." I have to admit, although I like the actor and the character, I had issues when he took command and was trying to "score" his performance by comparing to Captains April, Archer and Pike.

Getting back to the Prime Verse is only half the problem, it all depends on when they get back. With only a couple of episodes left, can we really say that the Mirror 'Verse is done with us yet?

This has been the longest incursion into the Mirror Verse of all Trek, and the elongated storyline was quite a welcome thing.
