“Shattered” is episode eleven of season seven of Star Trek: Voyager.
Icheb is in the cargo bay with Naomi, teaching her genetics using a jigsaw puzzle when Chakotay enters. Icheb explains what he’s doing – but don’t tell Seven; he’s supposed to be writing a paper. Chakotay agrees – if Icheb doesn’t tell Neelix about his stash of genuine, not replicated, Antarian cider. Icheb suggests storing it with the Borg items.
Chakotay arrives at the captain’s quarters with the cider; dinner isn’t ready as the replicator is in pieces. Chakotay explains Icheb and says in a few years he may be running the ship. Voyager shakes and the captain contacts Harry on the bridge. Gravimetric surges are overloading the dampers and Gravimetric there are problems with the warp core. Chakotay heads to engineering and the captain arrives on the bridge as Seven is reporting a spatial rift is opening. The ship gets hit with a bolt of energy and some surges from the warp core to Chakotay. B’Elanna has him beamed directly to sickbay, as part of his face has aged.
Chakotay comes around in sickbay; the Doctor says his body was in a state of temporal flux, but the Doctor fixed it. The Doctor doesn’t know about the rest of the crew and the bridge isn’t answering. Chakotay is heading out to treat any injured and tells the Doctor to come with. The Doctor reminds him he’s stuck in sickbay. What about his mobile emitter? What’s a mobile emitter?
Chakotay heads to the bridge, but when he passes through something the med kit he was carrying vanishes. The bridge has far more crew than usual and Chakotay grabs Harry and asks what’s going on. Janeway wants Chakotay taken into custody. They’re just about to head into the Badlands. Yes, this is from the beginning of “Caretaker” and Chakotay says he’s been sent seven years into the past. Check for strange temporal readings. The captain wants Chakotay taken to the brig; the two security officers disappear in the turbolift when it passes through a temporal barrier.
In engineering, Seska and the Kazon are still in control. Chakotay is knocked down and when he comes around, he mentions this being five years in the past. Chakotay is able to get away through another temporal change. He arrives back at sickbay and asks the Doctor for the stardate; a year before the Doctor got his mobile emitter. Chakotay explains that the ship is fractured with different parts in different time periods. Chakotay can cross from one to another; the serum must make him immune. He wants a hypospray also treated with another dose.
Chakotay speaks to the captain again. She’s realised something strange is going on. She’s reluctant to use the hypospray, as it might be poison. So Chakotay takes her hostage, pretending it is, then injects her, allowing her to pass though the times.
They head to the astrometrics lab. What astrometrics lab? Harry will design it. It has temporal sensors that will help map the ship. Harry invented temporal sensors? No; that’s Borg tech. Janeway decides under the Temporal Prime Directive, the less she knows the better. They come across people unconscious in the corridors – Chakotay gives two possible encounters as explanations – and arrive in astrometrics, to find an adult Naomi, now a lieutenant, and an older Icheb. Who looks to be the captain.
In their timelines, Chakotay and the captain died 17 years ago. They’ve mapped the ship temporally as well. The surge interacted with the warp core and shattered the space time continuum on the ship. That section appears to have been obliterated. Seven would be useful, but she hasn’t been found.
They head to the cargo bay. Which is full of Borg. Chakotay says this must be the time they forged a temporary alliance with the Borg. Seven is still a drone and explains how Borg cubes manage the temporal stresses of transwarp. Doing it the same way can’t be done, but Janeway suggests using the gel packs and injecting them with the serum. Seven suggests that if the two are assimilated into a small Borg collective, it would be more efficient. That’s a pass.
There are references to events from a number of different episodes and Chakotay is just casually mentioning things. Space pitcher plants, macroviruses, the Borg. Though also trying not to say too much. Fortunately – thank you, “Shades of Grey”! – it isn’t a clip show.
