It’s worth a word on the title, I think. What it refers to, largely, is obvious. The first part, “The Battle Without”, is easily understood; alluding to the past nine months, it signifies the Klingon war – the battle – without the USS Discovery to turn the tide. The Federation is no longer on the brink of war, but they’ve essentially lost it; arguably, this universe is now just as driven by strife and conflict as the Mirror Universe we just left. More abstractly, though, it denotes a lack – what are they “without”? In turn, then, it’s worth looking at this episode to see what’s absent.
What’s missing is Captain Lorca. Our attention is drawn to this at the beginning, with Sarek’s dramatic reminder of his death; it’s worth interrogating just why this line was delivered as it was, given it’s not a revelation for the Discovery crew or the audience. In essence, it’s a statement of intent, an indicator that this episode takes place in the shadow of Captain Lorca. Despite this, it’s oddly easy to forget, in fact, what’s missing; the crew gel so well in his absence, but then that’s also part of the point. There’s an emphasis on the Federation values, at least amongst the crew and on the ship; the scene shared between Tyler and the rest of the crew is telling in this regard, as is the terraforming to create new spores.
I quite liked this episode! And I quite liked this review, too. I think it’s a decent piece of writing.
