This week, the middle episode of a mid-range arc in the middest of all the shows in the Star Trek franchise. Trip and Malcolm are trapped in various rooms pressing buttons, while the Tellarites and Andorians are on their usual space alien bullshit. Harmless.

Strange New Worlds jumps genres this week to create something hitherto inconceivable in Star Trek: a high-stakes space problem that can only be solved with a massive, heartfelt musical finale.

This week, the crew of the USS Voyager awaken an ancient evil and unleash it upon the Delta Quadrant: the Vaadwaur, a phantom army that appears out of thin air, destroys entire colonies, and vanishes in the blink of an eye — but whose soldiers’ physiognomy is such that few men can find them afterwards.

There’s a get-to-know-you buffet at 1930 this week, as the crew of the Defiant team up with the Jem’Hadar to fight some Jem’Hadar rebels who want to take over the Galaxy. And, surprisingly late in the series, we get the first appearance of Jeffrey Combs as Weyoun.

This week: a party. The crew of La Sirena turn up at a lavish black-tie gala for some top-quality character work, only to be overshadowed by an incredible musical number by Alison Pill and a lovely scene of kindly encouragement from Patrick Stewart. But then they find themselves overshadowed, in turn, by the ineffable hotness of Santiago Cabrera.

Three plots for the price of one this week on Deep Space Nine. In reverse order of importance: (C) we all stand around in Ops talking about the computer; (B) Julian gets some funny lines and a pleasantly unsurprising character arc; and (A) Odo and Lwaxana are trapped in a lift together with nothing to do but some amazing and even quite moving acting. Underrated, but mostly by people who don’t enjoy things that are good.

When Q first turned up on the Enterprise bridge in 1987, he came to teach all of humanity a lesson about its terrible past. But this week his mission is more personal: to teach Picard how much he owes his young, undisciplined self, and to remind us that youth is silly and difficult, and that the people living through it deserve our respect.

(On that topic, if you wish to see the inspiration for Joe’s preferred 1990s hairstyle, you should check out the cover of Star Trek: The Next Generation — Boogeymen (1991) by Mel Gilden.)

Sometimes everything just comes together — a dull script, routine design, a generic score, perfunctory direction, an uncharismatic leading man and a guest star’s strange and flaccid performance. Meanwhile, on Star Trek: Voyager, Tom screams at his long-suffering girlfriend after falling in love with a car or something.

This week, we witness the ascension of Star Trek: Lower Decks, as it finishes its run on television and becomes a show fuelled by interdimensionality itself — decoupling its superpositions and spriralling off into an infinite number of unseen quantum possibilities. It’s funny and heartwarming and visually arresting, of course, and we can’t imagine what life would be like without it. Engage the core!

This week, Tendi and T’Lyn learn the usual Star Trek lesson about co-operation and competition, Boimler and Rutherford learn that Starfleet uniforms are less absorbent than is sometimes necessary, and Mariner learns that the real Inner Light experience comes from the friends (and murderers) we meet along the way. And Data shows up too, is just as delightful and wise as we always expect him to be.
